2003 GMC Questions and Answers


  • Comparison of Gooseneck and 5th Wheel Hitch For 2003 GMC Sierra 2500 HD Diesel Truck
  • Yes, there are fifth-wheel to gooseneck adapters and we do carry them. Gooseneck hitches are typically used to haul construction or agricultural trailers and fifth-wheel hitches are mainly used to haul campers. Gooseneck hitches are usually rated to haul 25,000 to 30,000 pounds, some fifth-wheel hitches are capable of doing the same, but other fifth-wheel hitches are rated lower. When towing, your towing setup is only as strong as the weakest towing component, whether it is your hitch,...

  • Towing Mirror with Maximum Extension for 2003 GMC Sierra 2500
  • The Longview Towing Mirror, part # CTM1500 would extend just a bit more farther than the CIPA # 10801 and 10802 you are currently using. If you look at the provided photo I provided, you can see that the CIPA product extends 5-1/2 inches beyond the edge of the factory mirror while the Longview # CTM1500 extends by 5-1/8 inches. I do not believe the 3/8 inch larger extension offered by the Longview mirror would make much difference to you. Even a Custom Extendable Towing Mirror like part...

  • Replacement 7-Way Trailer Connector Mounting Bracket for a 2003 GMC Sierra 2500HD
  • We do have a bracket that may work for you, # PK12711U, but it is designed to hold a 7-Way that mounts to a bracket using 4 screws. The other option is to replace the 7-Way using # 30955 which includes a 7-Way and a 4-Way and has a bracket.

  • How to Correct Surging or Bucking When Towing 5th Wheel Trailer Using Gooseneck Adapter
  • Any type of adapter will introduce some degree of additional motion, noise and/or vibration in a towing system. The Convert-A-Ball Cushioned 5th-Wheel-to-Gooseneck Adapter # CAB-C5G that you referenced and the offset version # CAB-C5GX1216 are no exceptions, and although these do include polyurethane cushions that act as shock absorbers, they will not deliver the same performance as a system without adapters. There is no quick-fix to the ride quality issues you're experiencing, but we can...

  • Can Gooseneck and Fifth Wheel Hitch Be Installed in Truck Bed At Same Time
  • There is not a bracket kit that would allow both a fifth wheel and a gooseneck hitch to be installed together, however there are solutions that might allow you to swap back and forth, depending on what you currently have installed. If you have nothing installed in your truck bed at this time, you can use the # RP30035 kit you mentioned to install 5th wheel rails. Install the 5th wheel into the rails when needed, and when you need to tow a gooseneck, remove the fifth wheel and install...

  • Can You Back Up a Trailer when Using Weight Distribution
  • Some weight distribution system prohibit reversing because doing so could damage the system. If you are backing up in a straight line though it would be fine. But to make turns while backing up you would need to disengage the spring bars and/or the friction sway control unit, like on # PS49903, and then maneuver the trailer. Some systems do not have this restriction including the Reese Strait-Line systems and Blue Ox Sway Pro systems. If using a weight distribution system that does not...

  • Trailer Brake Controller Recommendation for a 2003 GMC Yukon XL and 2012 Crossroads Sunset Trailer
  • For your 2003 GMC Yukon XL, I recommend the Tekonsha P2, # 90885. It is one of our most popular controllers because it is easy to set up and use and it offers diagnostics. The P3, # 90195, is a great controller but is geared more towards individual with brake controller experience. It has a lot of diagnostics and features, though and would work well. Both controllers are compatible with electric trailer brake systems as well as electric over hydraulic systems. For your Yukon XL, you...

  • E1 Error Code On Hopkins Trailer Brake Controller on 2003 GMC Sierra
  • If you press the manual button on the Hopkins Agility brake controller, # HM47295, and the trailer brakes work, then the problem is in the position of the red wire on the wiring harness under the dash. You might have a wrong brake controller wiring harness. The correct harness is the Universal Brake Control Wiring Adapter 2003 - 06 Chevrolet, GMC, Cadillac, # 3015-S. If you unplug the harness and check the wire locations on the connector, with the blue locking clip in the down position...

  • How To Install Safety Chain Attachment U-Bolts With Ranch Hitch Gooseneck to 5th Wheel Adapter
  • Which U bolts you will need, depends on the manufacturer of your gooseneck hitch. If you have Curt Quick Goose 2 Gooseneck Hitch, you will need Safety-Chain U-Bolt Kit for Curt Quick Goose 2 Gooseneck Hitch, part # C113. If you have a Reese or Draw-Tite Remov-A-Ball Goosneck Hitch, you will need Replacement U-Bolt Safety Chain Kit for Remov-A-Ball Gooseneck Hitch, part # 6308. You could also install part # 6308 in your truck bed to use with other brand gooseneck hitches. You would...

  • Can Transmitter on Peak Wireless Back-Up Camera # PKC0RB Be Mounted Behind Tail Light Assembly
  • The closer you can get the transmitter to the monitor, the better your reception will be and the less interference you will get. Wireless back up cameras operate at 2.4 GHz, which is a pretty common frequency. The closer the transmitter is to the monitor the more stable the picture. You might be able to mount it behind the tail light assembly, but I would try to get it in the cab. It is recommended to keep the transmitter out of the elements. The wire from the camera to the transmitter...

  • Troubleshooting a Sticking Handle On a Reese 16k 5th Wheel Hitch
  • The 16K Fifth Wheel Hitch by Reese, item # 30047, has a groove in the handle that a latch rotates into. If the latch is not rotated toward the rear of the truck then the handle will not move and hitching should not be possible. If the latch was not rotated and hitching was attempted then some of the handle parts could have been bent. During normal hitching you should not move the handle out. You should back the truck slowly into the trailer and allow the hitch to move the handle out. Once...

  • Under-Bed 5th Wheel Hitch Puck Placement on Ford and GM Trucks
  • Under-bed 5th wheel hitch puck placement is different between Ford and GM vehicles. Hitches that fit one do not fit the other. On a Ford truck the pucks are spaced 13-inches apart front-to-back and 30-inches apart side-to-side. On a GM truck the pucks are spaced 22-inches apart front-to-back and 27-inches side-to-side.

  • Fifth Wheel Hitch Positioning in 2003 GMC Sierra Short Bed
  • The installation instructions for the standard 5th wheels hitches (by Hidden Hitch, Draw Tite and Reese) indicate that the front rail needs to be placed 47 1/2 inches from the lip or end of the truck bed (before the tailgate). These instructions for the 2003 GMC 2500HD short bed truck are available for your review on on line and are guidelines only. Actual installation is the responsibility of the installer and the owner. Always measure the truck and trailer before installing the hitch...

  • Location to Install Brake Controller Power Fuse on 2003 GMC Sierra
  • I am assuming you are speaking of the fuse that activates the power feed to the brake controller. The 30 amp fuse is installed in the power distribution box as shown in the photo I have edited. The power distribution box is located under the hood, on the drivers side on the fender well. I have linked you to an FAQ article that describes how to install a brake controller on a 2003 GMC Sierra.

  • Tongue Weight Capacity when Using Titan Trailer Hitch Extension RP45292 with Weight Distribution
  • A weight distribution system is used to more evenly distribute the weight of the trailer to all axles of the trailer and tow vehicle. When using the extension, # RP45292, the tongue weight capacity is going to depend on the length the extension is cut to. If it is cut down to 24 inches, the tongue weight capacity 600 pounds. At the 34 inch length the capacity is 450 pounds. It does not sound like you have a weight distribution if you are using the extension and a ball mount and are connected...

  • Left Brake Light and Turn Signal not Working on Trailer Towed by 2003 GMC Sierra
  • I suspect that you have a blown fuse. The fuses that manage your towing circuits are located in the power distribution box located under the hood of your truck. The box sits on the inside fender on the drivers side. Your owners manual should be able to tell you which particular fuse to look for. Once you replace the fuse, you will need to determine why the fuse blew. Carefully examine your trailer connector for corrosion or damage. Check your left turn/ brake light wiring on the...

  • Hitch Recommendation for a Rockwood Roo Trailer
  • If your Rockwood Roo has a frame width between 24 and 46 inches you would want the Draw-Tite Multi-Fit Hitch, part # 5350. This hitch has a 500 lb tongue weight capacity and a 5,000 lb total trailer weight capacity. Another hitch to consider is the Curt Hitch part # C13701 that will fit 18 to 51 inch frame widths and has a 500 lb tongue weight capacity and 6,000 lb total trailer weight capacity.

  • Will the SumoSprings Custom Helper Springs Fit on a 2003 GMC Yukon XL With Coil Springs
  • I spoke with my contact at Super Springs and the SumoSprings Custom Helper Springs, # SSR-204-40, will fit on your 2003 GMC Yukon XL with coil springs as long as it is a 1500 model. These springs are designed to replace your factory bump stops. Once you remove your factory bump stops these springs will slide into the bump stop mounting location. The installation instructions are included in the box. I have attached a photo showing how the SumoSprings will look once installed.

  • Why Can't Blue Ox Hitch Extenders be Used to Tow a Trailer
  • The Blue Ox extender # BX88264 is not rated for or tested for use with a trailer by the manufacturer so that is why it can't be used for towing a trailer. We have an extender, # ST18, that is rated for 7,000 pounds gross trailer weight and 700 pounds tongue weight when used with weight distribution. But it is 18 inches long. There isn't a 12 inch long model available.

  • Can Power Folding Towing Mirrors be Installed on a 2003 GMC Sierra 1500HD
  • In order to install power folding mirrors on your 2003 GMC Sierra 1500 the truck would have to have had those features originally. If it did not then whatever extra features that the new mirrors have would not work. For example, if you installed K-Source mirrors # KS62075-76G on your truck but the factory side mirrors did not have heat, electric operation, or turn signals those features would not work even though the new mirrors have those features. If your stock side mirrors have...

  • Can Both 7-Way and 4-Way Be Used at Same Time on Pollak 7- and 4-Pole Trailer Connector
  • There is power running to both sides at the same time on the Pollak 7- and 4-Pole Trailer Connector # HM40975. However, using both at the same time could result in over drawing power which could lead to blown fuses, electrical fire, accessories not working and so on. It is not recommended so use caution.

  • Is Wedge Required When Using Reese Revolution Pin Box With Husky Fifth Wheel Hitch
  • You will definitely want to use a wedge when towing because the wedge locks the king pin in place and moves the pivot point back 22 inches allowing you to make turns with the fifth wheel. If your Husky 15K hitch in the truck has dual jaws, the universal wedge that came with the Revolution should work for you. If you cannot lock the jaw on your fifth wheel hitch with the universal wedge that came with your Revolution, my contact at Reese said the wedge that will work is part # SWW-04....

  • Will the Topline 2 Bike Truck Bed Rack Work with a Clamp on Tonneau Cover Without Damaging Rails
  • The Topline 2 Bike Carrier, # UG2500-4, is designed to clamp around the bed side rail and would most likely not work with a clamp on style tonneau cover, like the LiteRider Roll-Up Tonneau Cover by Access, # 834532001088. It will depend on the style of clamp on rail that your tonneau uses. I attached a photo showing the style of clamp on rail that the LiteRider Roll-Up tonneau uses, see link. Another option for carrying bikes in the bed of your truck would be the Softride Tailgate Pad...

  • Why Would Trailer Brakes Lock Up in Rhythm with Blinker Circuit
  • The problem is that someone either ran your brake light/blinker circuit to the brake output circuit of your vehicle 7-way, or the two circuits have shorted out together. I attached a diagram that shows how a 7-way should be wired up so that you can clean up the wiring of your vehicle.

  • Replacing Bearings, Races, And Seals On 2000 Coleman Pop-Up Camper
  • The best way to make sure you get the correct replacement bearings, races, and seals on your 2000 coleman Pop-up is to find the numbers stamped onto the metal of the inner and outer bearings that are currently on the trailer. With those you will be able to find the correct replacement bearings, races, and seals from the attached product page. If you are unable to find the numbers you will need to measure the spindle of your trailer with a digital or dial caliper to get the diameter...

  • How to Wire in a Brake Controller on a 2008 Monaco Windsor Motorhome
  • You are correct, the blue wire goes to the brake output circuit of the 7-way on your motorhome, the white wire goes to the ground of your battery, the black wire will run to the positive post of your MH battery through a 20 amp circuit breaker like part # PK54220, and the red wire goes to the cold side of your stop light switch on the brake pedal, in your case it should be the wire number 102 in your fuse control center. This circuit will see 12 volts when the brakes are applied and none...

  • How to Wire a Brake Controller to a 2003 Monaco Windsor Motorhome
  • To install a brake controller in your 2003 Monaco Windsor built on a Roadmaster chassis you will need to hardwire it. I attached an FAQ on how this would be done. Basically you will need to run the blue wire from the controller back to your 6-way. The black wire will run to the positive post of your MH battery through a 20 amp circuit breaker like part # PK54220. The ground wire will run to the negative side of your battery. The red wire will need to be run to the fuse control center,...
