Expert Answers about Chevrolet TrailBlazer


  • How to Install a Switch for Spot Roamer LED Bumper Lights on a 2004 Chevrolet TrailBlazer
  • To install a toggle switch for your Spot Roamer, you will first need a switch. I recommend the LED Micro Bug Push Button Toggle Switch, part # PL-SW28B. For the wiring, you will need to take the ground wire of the lights and attach it to bare metal. Then, take the power wire of the lights and connect it to the white wire of the switch. From there, you will need to ground the switch's black wire. Finally, the red wire of the switch will need to be ran to the battery with a 5 amp inline...

  • How to Power Dutton-Lainson Winch # DL25200 with 2008 Chevy TrailBlazer
  • Would you be able to send me some pictures of your setup? Typically winches like the Dutton-Lainson TW4000 StrongArm Electric Winch # DL25200 are installed on the boat trailer and they draw power from either the tow vehicle battery via the 12V Power pin on the 7-Way connector, or from a separate battery. If you can give me some more details about how your winch is configured and what you have on your pickup and your Trailblazer I would be happy to help you get it switched over!

  • Bypassing Factory Transmission Cooler on a 2003 Chevy Trailblazer LT 4.2 I-6
  • It is possible to bypass the factory transmission cooler on your 2003 Chevrolet TrailBlazer, but I would not recommend doing this with the Derale Series 8000 Plate-Fin Transmission Cooler # D13503. The cooler is a Class III cooler and as such, it's not quite big or efficient enough to function as a primary cooler. I contacted Derale and they recommend the Derale 9000 Series # D33604. This is a Class V transmission cooler which provides more effective cooling and measures 10-1/8" wide...

  • How Does Prodigy RF Electronic Brake Controller Know When To Send Power To Trailer Brake
  • If you have a newer Trailblazer with the tow package there should be a total of 2 wires that you will need to connect; both wires should be red/black with eyelets on the end.

On the driver side, remove the fuse box cover, there will be 2 threaded studs that are different sizes, the wires which have different sized eyelets will connect to the corresponding studs using...

  • Is Brake Light Relay Required when Installing Even Brake on a 2002 Chevy Trailblazer
  • From what I was able to find out, you will not have to install the brake light relay, # RM-88400, when using the Even Brake, # RM-9400, and tow bar wiring on your 2002 Chevy Trailblazer. But the one way to verify this for sure is to get in the Trailblazer without the key in and step on the brake pedal. If the brake lights light up then you will need a brake light relay.

  • Brake Controller Installation on 2008 Chevy Trailblazer
  • The orange wire found under the dash that would provide power to the brake controller is already circuit protected, so you would not need an additional circuit breaker like the # 9506P you referred to. The wiring connections would be made as follows: Orange tow pkg wire connects to black wire on controller Dark blue tow pkg wire connects to blue wire on controller Light blue tow pkg wire connects to the red controller wire Black tow pkg wire connects to the white brake controller wire The...

  • Does the Blue Ox Base Plate Kit for a 2022 Chevy TrailBlazer Require Fascia Trimming
  • In regards to the Blue Ox Base Plate Kit part # BLU49FR which is a fit for a 2022 Chevrolet TrailBlazer, you do have to trim the fascia to allow the tabs to protrude through but this is standard practice for the vast majority of base plate kits and everyone for this vehicle. That said, you're only trimming a small portion. The instructions indicate to hold the fascia up to the vehicle with the base plate installed and make your marks that way to ensure as little material as possible is removed.

  • Does the Tekonsha Prodigy P3 Turn Off
  • The Tekonsha Prodigy P3 Brake Controller, # 90195 will go into sleep mode after several minutes of inactivity, but there isn't an "off" switch for this controller. The power draw when it is in the sleep mode is so negligible that it will not discharge the battery, so there's nothing to worry about in that respect. If you want the brake controller totally off, then you would have to unplug the connector from the back of the controller so that it's no longer getting power.

  • Are Additional Parts Needed for Separate Wiring When Installing Roadmaster Light Kit RM-15267
  • For a vehicle with separate lighting, it is not necessary to use additional parts when installing the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. The kit will work, but it will cause your brake lights to function as both the brake and turn signal lights. If that's okay with you, no other parts are needed, but if you want to keep your brake lights and turn signals separate you will just need to add a converter, the Vehicle to Vehicle Tail Light Converter # 118158...

You will need to free those wires so the P3 # 90195 can be installed. The wires on the vehicle will not match color to color so you will need to attach them in the following manner. The black wire from the brake controller attaches to the orange wire on the vehicle. The blue...

  • Running Light Function of 2004 Chevy Trailblazer When Flat Towed Using Roadmaster # RM-154
  • The Roadmaster Universal Hy-Power Diode Wiring Kit # RM-154 is designed to allow your 2002 Dutch Star Motorhome to power all the lighting of your 2004 Chevy Trailblazer when being flat towed. You should not have the running lights of your Trailblazer turned on independently of the running lights of your motorhome when connected. That could cause the diode to fail but the kit is rated for a max voltage of 24V and max amperage of 85 amps, so it may function even under those conditions.

  • What is the Correct Distance Between the Spring Hangers When Using a e66SR Leaf Spring
  • The distance of 25-3/4 inches would be the correct distance to have between the spring hangers. You have to consider that as the the leaf spring compresses from the weight of the trailer it will flatten out and the overall length of the spring will increase so that the shackle will face the right direction.

  • Troubleshooting a Tekonsha Primus Brake Controller Displaying 0.0 and Not Braking
  • It sounds like there might be some other fuses that could have blown, or there are some shorts on your brake controller/7-way circuits. It is hard to know exactly where the problem lies, but the first thing I would check would be to test the manual override lever when the trailer is connected and see if it will apply the trailer brakes. If it does have voltage then I would check to make sure brake switch circuit (red wire) sees voltage when the brakes are applied. If not, then you have...

  • Trailer Brake Controller Installation on a 2008 Chevy Trailblazer with Factory Tow Package Wiring
  • We actually have a video of the Tekonsha P2, # 90885, being installed on a 2006 Chevy TrailBlazer that has the same wire colors as your 2008. They have found that the dark blue wire will connect to the brake controller blue wire for output to the 7-Way trailer connector. The orange wire should be the 12 volt power from the battery. You can use a circuit tester like # 40376 to be sure. It connects to the brake controller black wire. It provides power for the controller. The light blue...

  • 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.
