2004 GMC Questions and Answers

• No Tail Light Function on 16 ft Car Hauler Towed by a 2004 GMC Sierra 2500
  
• Based on your description, it sounds like your truck has a 7-way trailer connector. Anytime your trailer lights are not functioning properly, it is best to isolate the issue to either the truck or trailer. It sounds like you have already started some of the troubleshooting, but I will list the steps from the beginning just in case. The first and easiest step to take is to check the vehicle side and trailer side connectors for any corrosion. You said your wiring looks new, so this may not be

• No Power to Trailer Brake Controller on a 2004 GMC Sierra 1500 with OEM Tow Package
  
• Just to make extra sure, the red wire should be directly next to the blue wire on the harness. The black wire should be above (or below depending on how you are holding the connector) the blue wire. And the white wire should be in the opposite corner from the blue wire like in the picture I have included. When plugged in, the black wire should have 12 volt power. If it does not then you will check the under hood connections and make sure the corresponding fuses are in the right places and no

• Is the 2,500 Pound Capacity MaxxTow Electric A-Frame Trailer Jack Enough for 690 lbs Tongue Weight
  
• The 2,500 pound capacity of the MaxxTow jack # MT70146 will be more than enough for your 2007 Coachmen trailer with its 690 pounds of tongue weight. I have included a link to a video review of this jack for you.

• Platform Style Trailer hitch Mount Bike Rack for a 1-1/4 Inch Receiver on a 5th Wheel Trailer
  
• There are only certain bike racks approved for use at the back of an RV or trailer. I have included a link to the options for you. If you like the platform style racks then I would go with the Swagman XC, # S64650. It will fit the 1-1/4 inch receiver and is rated for use behind an RV or trailer. I have included a link to a video review and a link to the installation instructions for you.

• Will the Edge Evolution CTS Programmer Work on a 2004 GMC 2500 HD with Cold Air Intake System
  
• Yes, you can install the Edge Evolution CTS Programmer, # EP85250, on your 2004 GMC 2500HD with 225,000 miles and a cold air intake. When installing a programmer on a vehicle with high mileage, you will want to make sure the truck is in good running condition. Pre-existing, minor problems can turn into major problems once a programmer or tuner is installed. I would recommend having a tune-up done before installing the programmer and ensure you are not having any problems. Edge states that the

• Procedure for Installing Curt Class V Hitch on 2004 GMC Yukon with OEM Hitch
  
• I spoke with my contact in the Tech Services department at Curt Manufacturing. I was told that installing the # C15324 on your 2004 Yukon would be a simple matter of unbolting the existing hardware holding the factory hitch into place, removing the hitch and installing the # C15324 according to the instructions. Keep in mind that although this hitch has a 16,000 lb towing/ 2,400 lb tongue weight capacity, your actual capacity might be limited by the actual towing capacity of your Yukon, if

• Weight Distribution System for Chaparral Horse Trailer Towed By 2004 GMC Envoy
  
• The first step in choosing a weight distribution system is to definitively identify the fully-loaded and ready to tow tongue weight of the trailer. There are a few methods of doing this, as you can see by clicking on the link I provided. Knowing the exact tongue weight is a crucial step in choosing the correct system for your application. If you choose a system that does not have a high enough capacity, the system will not be effective and could be damaged. Choosing a system whose capacity is

• Replacement Pop and Lock Tailgate Lock for a 2004 GMC Sierra
  
• All the Pop and Lock assemblies we sell for your 2004 GMC Sierra utilize the factory tail gate handle, that may be why the ones you see do not look like what you have. Since the latch handle and everything appears factory like the # PAL1700 I am going to assume you need the power model available for your vehicle. For that you would want the part # PAL8110. You will still need a factory handle since yours is damaged and this does not come with one. You might try a junk yard or an online aucti

• Will Reese Universal Mounting Brackets # RP58314 Fit on 2004 GMC 2500HD
  
• Yes, the Reese Universal Mounting Brackets, part # RP58314, you have referenced will work on your 2004 GMC 2500HD. These are just the mounting brackets. They are designed to be used with the Reese Universal Base Rails, part # RP58058. If you need just the brackets (# RP58314) and mounting hardware minus the base rails you would want part # RP30439. If you need the installation hardware plus the base rails you would want Reese Universal Base Rails and Installation Kit, part # RP30035. If

• Installing Brake Controller On 2004 GMC Van
  
• The 2004 GMC van will not have the connector under the dash like those found in GM trucks. If the van has the OE 7-way connector at the rear bumper, the blue brake output wire will be ran from the 7-way to the area near the emergency brake pedal and would connect to the blue wire on the brake controller. We do not offer a plug for the controller, so you would need to remove it. The remaining wires would need to be hardwired. The white wire would run to the negative battery terminal, the black

• Metal to Metal Noise While Towing a 5th Wheel Trailer Coming from the Jaws of the 5th Wheel Hitch
  
• If this noise occurs during starts and stops or any time there may be back and forth movement of the trailer then it is normal to get some metal to metal contact as the trailer king pin bumps around in the jaws of the hitch. The double jaw design of the Reese 5th wheel hitch, # RP30051, is secure but it is not so tight that it will eliminate all movement. You also want to make sure the trailer is not high hitched. This means that the king pin is not fully seated in the hitch. When hooking up,

• Weight Distribution and Sway Control Recommendation for a 2004 GMC Yukon XL and 7,000 lb Trailer
  
• First, you would benefit from using weight distribution and sway control. Weight distribution should be used any time the trailer weighs at least 50 percent of the vehicle. Sway control will be very useful since the trailer is so heavy. If that trailer starts to sway it would make it difficult to keep the Yukon and trailer straight. Regarding a different trailer hitch, the hitch on your 2004 GMC Yukon XL has the capacity to tow your trailer when loaded and ready to tow if you are at the 6,500

• Transmission Cooler Recommendation for a 2004 GMC Canyon
  
• I did some checking and you should have a factory transmission cooler in your 2004 GMC Canyon. It will be near the bottom of the radiator. If you plan on doing any towing I would strongly recommend you install an aftermarket transmission cooler in conjunction with your factory transmission cooler as factory coolers are usually adequate at best for vehicles that are not towing. You will need to measure the distance in front of your radiator to see how much room you have for a supplemental cool

• Does the MagnaFlow Catalytic Converter # MF45036 Require Welding to Install on a 2004 GMC Canyon
  
• The MagnaFlow Stainless Steel Catalytic Converter, # MF45036, does require welding for installation. All universal fit converters will require welding for installation. If you can tell me the size of the engine in your 2004 GMC Canyon, if it is a 2WD or a 4WD and if it is registered in California or not, then I can see if there is a direct fit converter that does not require welding for you.

• Ball Mount and Ball Recommendation for the Swagman Towing Bike Rack # S64600
  
• First, there are 3 ball mounts that we recommend for use with the Swagman towing bike rack, # S64600. We have # 2736, # 80233, and # D-28. Any of these ball mounts offer enough length for the rack to fit. There may be other ball mounts that you can use if you need a different rise or drop to tow the trailer level. Just make sure that there is at least 10 inches from the center of the hitch pin hole to the center of the ball hole on the ball mount. A GMC Yukon XL has a fairly high receiver

• Replacing an Old Draw-Tite/Hidden Hitch Weight Distribution and Sway Control System
  
• If the weight distribution system that is on the trailer is more than 3-1/2 to 4 years old, then you will need to basically replace everything and not just the spring bars. The problem is the newer parts are not compatible with the older parts. The new bars will not fit in the old head, so you would have to replace that as well. And since you will be adding dual-cam sway control, you might as well replace the whole system because the cost is about the same. My recommendation is a new system.

• Weight Distribution for 5000 lb Travel Trailer Towed by 2004 GMC Sierra
  
• When choosing a weight distribution system, ideally the tongue weight of the trailer will fall right in the middle of the effective range of the system. Make sure that the tongue weight figure you use includes the fully loaded and ready to tow tongue weight of the trailer. The weight of anything stowed behind the rear axle of the tow vehicle also needs to be included in the tongue weight figure. If the 405 lb TW figure you mentioned represents the dry tongue weight that does not include the w

• Can Firestone Ride-Rite Air Springs be Installed on a 2004 GMC Sierra 2500HD with 3 Inch Lift
  
• You can use the Firestone Ride-Rite system, # F2250 on your 2004 GMC Sierra with the 3 inch lift. You will need to use Lift Spacers, # F2368. The spacer height must be the same as the lift height and these are 3 inch spacers. Since the Firestone system fits on the axles, see instructions link, this is the correct kit for systems that fit on axles. I have included a link to the installation details for the spacers as well. And, I have included a link showing typical installation of the Firest

• Air Lift LoadLifter 5000 Recommendation for a 2004 GMC Sierra Ex Cab 4X4 1500
  
• While it is not required that you install an air-suspension system on your 2004 GMC Sierra extended cab 4x4 1500, it will most certainly help with the ride quality, handling and braking of your vehicle once installed and properly setup. I would recommend one for you as they do make a difference. With that being said, the Air Lift LoadLifter 5000 # AL57286 that you referenced is designed for 3500, 2-wheel drive cab and chassis model trucks. You would want an Air Lift LoadLifter 5000 # AL57250

• 5th Wheel Installation Brackets Needed for a 2004 GMC Sierra With Existing Rails and 5th Wheel Hitch
  
• For your 2004 GMC Sierra 2500 HD, you can use the Reese Quick-Install Custom Bracket Kit, # RP50064, which includes all of the under bed hardware for installing a set of Reese, # RP58058, rails. You will also need above bed hardware, # RP58430, to mount your above bed rails to the below bed brackets. If you have CURT Rails, # C16204, then you could use the CURT Custom Fifth Wheel Bracket Kit, # C16418, along with your existing rails. No other hardware would be needed. We do not recommend m

• Is Chrome Trim Raised or Flat on Putco Chrome Tailgate Accent # P403413 For 2004 GMC Sierra Truck
  
• I contacted our representative at Putco about the Putco Chrome Tailgate Accent # P403413. The representative at Putco informed me that this chrome trim piece does have a raised curve to the center. The # P403413 installs with double sided tape and will fit your 2004 GMC Sierra. To go along with the Chrome Tailgate Accent, you may also be interested in the Putco Chrome Tailgate Handle, part # P400017. The # P40017 covers the entire handle and trim of the tailgate handle.

• Will Thule Flat Top Ski and Snowboard Carrier # TH92725 Fit Factory Cross Bars on 2004 GMC Yukon
  
• If your 2004 GMC Yukon has factory crossbars that run from side to side, then the Thule Flat Top Ski and Snowboard Carrier, part # TH92725, will fit your vehicle. If you just have the factory installed side rails that run from front to back on your Yukon, then you will need to use the Thule Snowcat - Rooftop Ski and Snowboard Rack, part # TH5401. I am including a link to the installation instructions on the Thule Snowcat rack. You can use the Thule Flat Top Ski and Snowboard Carrier, part

For a 4-Way to 4-Way Round Kit, use # RM-164. If your are towing the 2003 GMC Sonoma behind another vehicle, I would need to know what connector the truck has at the front and what type of connector the towing vehicle has at the back. If you are using the Sonoma to tow another vehicle, I would need to know what it has on

• Correct CURT Fifth Wheel Trailer Hitch Placement in a 2004 GMC Sierra 3500 Long Bed
  
• I looked over the installation instructions for the CURT E5 5th Wheel and Installation Kit, # C16116, and for a 2004 GMC Sierra long box, 30 inches from the edge of the bed to the back edge of the rear rail is correct. This should put the center of the hitch jaws centered over the rear axle. You have installed the hitch correctly if you have followed the included instructions. Following an alternate installation method will void the warranty. Having the center of the hitch centered overall th

• Troubleshooting Trailer Lights When Trailer is Connected to 2004 GMC Sierra 1500 4X4
  
• It sounds like a problem with the ground or wiring on the trailer, but it would be wise to check all of the components in your wiring system. You can test the trailer connectors on the 2004 GMC Sierra and the trailer with a circuit tester like the Quickee Tester, part # 3808. I am including a link to a FAQ page on trailer wiring that will show you the functions of each pin on your connector, depending on if it is either a 4-Way, 5-Way, 6-Way, or 7-Way. This will help you determine if there is

• Trailer Connector Brake Output Pin on 2004 GMC Sierra Shows Constant 12-Volts
  
• Are you by chance using a 7-way to 6-way adapter on the vehicle? There are two generally accepted methods of wiring the 6-way connector. One uses the center pin as the 12-volt accessory power feed, the other uses the center pin for the brake output voltage. If the adapter is wired one way and the trailer is wired the other way, the brakes are going to get 12-volts immediately upon plugging the trailer in. If you are not using the adapter, your trailer connector is most likely wired incorrectl

The closest thing to the # F2190 that you referenced that is available for your truck is the Firestone Vehicle Suspension # F2320. I attached installation instructions for you to check out. The # F2190 is not a confirmed fit for your vehicle and I would not recommend it.
