2003 Chevrolet Questions and Answers


  • Tire/Wheel Combo to Replace 18.5 x 8.5-8 Tires on Snowmobile Trailer
  • The 18.5x8.5-8 is actually an old tire size that is not used much anymore. The closest metric size to your existing tire would be 215/60-8, which is what I would recommend. Your wheel most likely has a 5-on 4-1/4 inch bolt pattern (see link below), you will want to make sure that the bolt pattern of your existing wheels matches that of the replacement wheel. We offer a 215/60-8 load range C, 935 lb capacity tire on a white painted rim as part # AM3H200. When inflated to its 50 psi maximum...

  • Does 12V Pin on 7-way Trailer Connector Always Have Power
  • It sounds like you're asking about the 12V circuit on the 7-way trailer connector on the rear of your 2003 Chevrolet Trailblazer. Some vehicles will always have power and some others will not. We don't have this specific information for your vehicle, but to determine if your 12V always has power you can test the pin in the 1 O'clock position on your 7-way. The other pins will have power when the corresponding light is used or the brake pedal is pressed.

  • Replacement Mounting Hardware & Brackets for the Westin E-Series Round Nerf Bars # 23-1680
  • Yes, we can help you with replacement installation brackets for your Westin E-Series Round Nerf Bars # 23-1680 on your 2003 Silverado 2500HD. The correct replacement mounting kit for your truck and nerf bars is part # 23-168PK. This kit includes brackets, bolts and washers. Westin suggests an application of automotive wax on their stainless steel bars to help retain their high-polish finish. In case you are interested in other enhancements for your truck I have linked you to our...

  • Removing Cover of Fuse Box on 2003 Chevy Silverado HD to Activate Trailer Charging System
  • The fuse box in your 2003 Chevrolet Silverado HD is located on the driver-side engine compartment. Opening it will require removal of a support bracket in the corner closest to the driver. The fuse box is just forward of this bracket. With the bracket removed the top cover of the Accessory Fuse Block can be snapped off. Next you will remove the lower cover to reveal the auxiliary positive power posts. Please refer to the linked article on brake controller installation which provides detailed...

  • Location of Brake Controller Port on a 2003 Chevrolet Silverado 2500 HD
  • If your 2003 Chevrolet Silverado 2500 HD has the factory installed hitch and a 7-Way connector, then all of the wires for the brake controller have been run. The factory brake controller port is located in the black box underneath the dash on the drivers side, to the left of the brake pedal. Usually a brake control adapter will be included in the junction box. If an adapter is not in the junction box you can use the Draw-Tite Universal Brake Control Wiring Adapter, part # 3015-S, for...

  • Connecting to Generator from 50 Amp Service on RV
  • For the 3 prong 30 amp outlet on your generator, I recommend using the Power Grip Generator 30 Amp to 50 Amp RV Power Cord Adapter # CAM55412. The 3-Prong twist-lock design will connect with the outlet on the generator and the female end will connect with your RV's 50-amp power plug. This adapter is rated for up to 125 volts. For higher voltage items, you can use the Mighty Cord Generator Adaptor # A10-G30450VP. This is rated for up to 240 volts of power and will connect to the 4 prong...

  • Trailer Tire Recommendation for a Boat Trailer with 5.30-12 Tires and Towing at Highway Speeds
  • All of the ST (Special Trailer) tires that we carry are DOT (Department of Transportation) rated for 65 miles per hour unless stated otherwise on the tire. It is not recommended to run a trailer tire at a higher speed than 65 miles per hour due to the heat buildup that will occur inside the tire and cause the tire to break down and cause the tire to fail. All trailer tires are constructed with thicker sidewall dimensions for handling weight and are designed to be used at 65 miles per...

  • Trailer Left Turn Signal Pin has No Power on a 2003 Chevy Silverado or GMC Sierra Diesel
  • It could just be a tow package fuse blown on your truck. There is one for trailer left turn signal and brake light in the fuse box in the cab between the dash and driver's side door. It is labeled LT TRLR ST/TRN. You would not be able to tap into the trucks turn signal because your 2003 Chevy or GMC truck has separate turn signals and brake lights whereas the trailer connector and trailer use combined brake lights and turn signals on the same circuit.

  • Recommendations for Horsepower and Torque Increase On 2003 Chevrolet Silverado 1500 6.0
  • We do have a product that will help increase the torque and horsepower of your 2003 Chevrolet Silverado 1500 6.0, but the Edge Insight CTS # EP84130 is not equipped to do that as it is not a performance-enhancing device. It provides the driver with various vehicle data only. For a product that will provide the gains you are looking for, I recommend the Superchips Flashpaq F5 Performance Tuner # SU4845. This product is pre loaded with performance enhancements such as increased throttle...

  • Recommended Trailer Locks for Rented U-Haul Trailers to Secure When Connected and Disconnected
  • Since you are looking to lock your trailer when connected as well as when disconnected, I recommend the Master Lock Trailer Hitch Receiver Lock and Coupler Lock Set - 1-1/4" and 2" Hitches # 3794DAT. This kit will give you a hitch pin lock for your ball mount, the trigger lock for the trailer when connected or disconnected from you vehicle, and the coupler lock to secure it when disconnected. These locks are all keyed alike for your convenience. I've attached a video to assist.

  • Why do the K-Source Custom Towing Mirrors Reset the Adjustment when the Truck is Turned Off
  • It sounds like your truck has the Curb Assist feature which allows for your OEM mirrors to keep memory settings and automatically adjust. Unfortunately, the K-Source Custom Towing Mirrors are not designed to work with the Curb Assist feature on GM trucks because that is a patented feature that aftermarket manufacturers are not allowed to duplicate. If the Curb Assist feature was not deactivated, then the power settings on your mirrors reset every time you turn off the truck. K-Source...

  • Do the Trailer Tire and Wheel Combos Come Balanced
  • The tire and wheel combos we carry are not machined balanced. You can have the tire and wheel combos balanced at a local tire shop if you wanted to. What some manufacturers will do is line up the light spot on the tire with the heavy spot on the wheel. This is a type of balancing but not like how car tires are balanced (with weights on a balancing machine).

  • Replacement 7-Way Trailer Connector for a 2003 Chevy Silverado
  • The 7-Way trailer connector on the back of your 2003 Chevy Silverado should have a round plug behind it that plugs into another harness that continues up to the front of the truck. What you can do is use # C55774 which comes with a new mounting bracket and has both a 7-Way blade style connector and a 4-Way flat. Or you could use # PK11916 that you referenced if you just want the 7-Way. Both options are assuming none of the wiring was damaged. You can use a circuit tester like # ALL640595...

  • Replacement Brakes Needed for AxleTek Trailer Axle B12E-02 12-GG
  • We do carry the exact brakes that you need for your B12E-02 AxleTek 12-GG Axle. For the Left Assembly you will want part # AKEBRK-7L-SA and for the Right Hand assembly you will want part # AKEBRK-7R-SA. These brake assemblies are made by AxleTek and measure 12 x 2 inches. These assemblies come in a quantity of 1 so you will want to order 2 of each. I have attached a video of these brake assemblies being installed that you can use as a reference.

  • No 12 Volt Power Reaching Trailer Connector on 2003 Chevrolet Silverado 2500HD
  • In later model years (2007-2011) Chevrolet did not complete all the trailer wiring connections, but this should not be the case in your 2003 Silverado. If your 7-way has worked previously then there is a chance the connector is corroded or damaged, or that the factory wiring has failed. Check for signs of whitish or greenish discoloration on the contacts and apply an electrical contact cleaner as needed. Inspect the connector for damage and to ensure all wiring to the connector pins...

  • Wiring Codes AUX and CHMSL During Brake Controller Install on 2003 Chevrolet Trailblazer
  • The code AUX refers to auxiliary which is auxiliary power, which should be the Dark Blue wire on your 2003 Chevrolet Trailblazer. This wire will connect to the Dark Blue wire on the brake controller and should be connected to the 7-way as the brake output wire. The code CHMSL refers to Center High Mounted Stop Light, which is your third brake light circuit. This is the brake signal wire and will be connected to the red wire on the brake controller. This wire should only get signal when...

  • How to Monitor Exhaust Gas Temperature EGT on a 2003 Chevy Silverado with 6.6L V8 Duramax Engine
  • The California approved model of the Edge Diesel Evolution CTS2 Performance Tuner is part # EP85401, not part # EP85400. The tuner will allow you to view the exhaust gas temperature (EGT) of your 2003 Chevrolet Silverado on the display but you will need a probe to send the data from the exhaust system to the tuner. For this I recommend the EGT Sensor for Evolution CS and CTS Programmers part # EP98620. The EGT kit is designed specifically for the above tuner and will allow for full access...

  • Replacement 7-Way Trailer Connector for a 2003 Chevy Silverado 2500HD
  • I actually recommend that you use the Hopkins connector, # HM40975, because it comes with a 7-Way and a 4-Way and also comes with a bracket. The connection at the back is made to fit the factory harness on a 2003 Chevy Silverado that came with a factory 7-Way. I have included a link to a video that shows a typical installation for you. If you want to go with a regular 7-Way use # PK11893 and bracket # PK12711U.

  • What is the Difference in Load Ranges for 12 Inch Trailer Tires
  • Any given tire size can have more than one load range. The load range represents the ply rating for a tire size and the higher the ply rating the higher the capacity of the tire. Plies are the structural components inside a tire. A tire can have fewer physical plies than its ply rating. This is due to the strength of the materials used to make the plies. Trailer tire # AM10130 that you mentioned is indeed a load range D. It has an 8 ply rating. It is rated for 1,220 pounds at 65 psi....

  • Wiring a 2003 Chevrolet Kodiak C-5500 for a Brake Controller with Factory Style Wiring Harness
  • When wiring the red brake switch wire on the brake controller you should use a circuit tester to determine the wire that goes hot only when the brake pedal is pressed. If you find a wire that has voltage on it before the brake pedal is pressed and then gets brighter when the brake pedal is pressed that is the wrong circuit and should not be used. If your Kodiak has the prewired connector under the dash for the Tekonsha Wire Replacement for GM Vehicles, 2003 - 2006, then this should be...

  • Troubleshooting A Tekonsha P3 Brake Controller that Says Power on the Display
  • The Tekonsha P3 Brake Controller, item # 90195, has built in troubleshooting diagnostics that you can access by pressing the menu button then selecting help and pressing ok. You will then be able to monitor the battery voltage supplied to the unit, black wire, the voltage supplied when the brake pedal is pressed, red wire, and the output voltage and amps sent to the trailers brakes, blue wire. If one of these connections is wrong you should get a warning screen. If you have the caution...

  • Location to Mount 7-Way Connector In Truck Bed for 5th Wheel
  • Some model year trucks have a greater distance between the outer fender and the inside of the truck bed in the area directly behind the rear wheel well, which is typically why you see the trailer connector for the fifth wheel installed there. You could install the connector forward of the wheel well if you wish, but if you do, I would recommend using a 90-degree plug like the Bargman # 50-97-410. A 90-degree plug needs less space behind the bed wall. Keep in mind that you will need...

  • Recommendation for Reducing Side to Side Body Roll on a 2003 Chevy Tahoe 4 Wheel Drive
  • What I recommend to reduce roll is add some Timbren suspension enhancement. Part of what this system was designed for was the reduction of side to side roll. For a 4-wheel drive 2003 Chevy Tahoe, for the rear we have # TGMRG25C and for the front # TGMFK15A. What this system will do is reduce the space between the axles and the factory bump stops so it will not travel as far side to side. The spring will compress and the more tension put on it the more resistant it will be. I have included...

  • Troubleshooting Trailer Brake Lights Not Working on a 2003 Chevy Silverado 1500
  • Since the lights on the truck are working but the lights on the trailer are not, I am inclined to believe that the problem is on the trailer side but I do not want to rule out the truck just yet. First, I recommend testing the trailer connector on the truck side. You will need 2 things. First, you will need a circuit tester like # 40376 if you do not already have one. Second, you will need someone to sit in the truck to run the lights while you test the trailer connector. The brake lights...

  • Recommendation For Correct Weight Distribution System With Sway Control For Jayco Jay Flight Trailer
  • I would recommend the Strait-Line Weight Distribution System w Sway Control - Trunnion Bar - 12,000 lbs GTW, 1,200 lbs TW, part # RP66084. This weight distribution is suitable for trailers with a tongue weight between 600 and 1,200 lbs. Part # RP66084 also features dual-cam sway control which acts to prevent trailer sway before it starts. Part # RP66084 comes with all necessary hardware and includes the proper shank. You will need to purchase a 1-1/4 inch diameter hitch ball, with a...

For the Shur-Bond Velcro Brand Fastener you should need # TX1115174 which is 80 inches long by 1-5/16 inches wide. The header seals we can get. I am having the part added to our site, 1704787, and we will likely put a TX in front of that number. The seals are ordered by the foot so for one you would need 5.41 feet and for...

  • Transmission Cooler Recommendation for a 2003 Chevy Silverado 2500HD
  • You mentioned wanting the best cooler for your 2003 Chevy Silverado. The best, as in the most amount of cooling, is going to be a remote cooler with its own fan like # D13960. It does not matter where this cooler gets mounted because its fan offers the optimum amount of cooling all the time. Otherwise for a standard cooler that would require air flow I recommend # D13105. Its large surface area will provide plenty of cooling for your trucks transmission. To avoid cutting and flaring...
