Check to see if the switch is getting power. this can be done with a simple 12V light tester. If not, check fuses. There are fuse locators on the cover for each of the fuse panels. There is one under the hood, and one under the passenger rear seat. But since only one window is not working, Start at the master switch at the drivers door. This can be removed by carefully prying up by pushing in from each end of the cover. If power is getting to the switch, Then activate the switch up, and check to see if the switch is sending voltage to the drivers window motor. If not, replace switch. If power is coming out of the switch, check to see if it is reaching the Motor. Do this by removing the door panel by removing the bolt cover inside the handle and removing the 10mm bolt. Then remove the other 10 mm bolt angled towards the rear edge of the handle. Then pry out at the edges of the bottem. There are white fasteners that are pressure only clips. lift out at the bottem and raise up to remove. You will see a plastic layer between the door panel and the door itself. Carefully remove this from one edge to the other. You will need to replace this so don't damage it too much. This will give you access to the window motor. Check to see if the power is getting to the motor. If no trace wire back to switch looking for breaks or disconnects. Also check to see if the ground is getting good connection. If power is getting to motor, remove lever that attaches motor to window slide. Activate up switch to see if motor moves without being attached to window. If yes, Move window manually to see what is binding. If not, motor up actuator is not making contact. Clean connectors, if that doesn't work replace motor. reverse door panel removal procedures to install. Hope this helps. I bought a Haynes repair manual from Autozone $20. It has everything you will need for the DIYer. If you need more guidance than the book offers. I found a site called trailvoy.com. These guys help with anything for free.

First check fuse #10 in the rear fuse panel, if fuse is OK, the Driver's Door Module (DDM) is probably bad due to water intrusion. You could try swapping in the module form the passenger side to verify.

Tailgate on a 2002 trailblazer will not open. unlock button wont let it open. what fuse do I need to check or do I open from inside?


  • There was a Technical Service Bulletin concerning this.

  • Bulletin No.: 03-08-52-002
  • Date: March 27, 2003

  • Technical - Subject:
  • Remote Keyless Entry Inoperative (Reprogram Liftgate Module)
  • Models:
  • 2002-2003 Chevrolet TrailBlazer, TrailBlazer EXT
  • 2002-2003 GMC Envoy, Envoy XL
  • 2002-2003 Oldsmobile Bravada
  • Condition
  • Some customers may comment that the Remote Keyless Entry (RKE) is inoperative at times.

  • Cause
  • An anomaly has been identified with the software in the Liftgate Module (RKE functions). The Liftgate Module software is affected when the temperature is approximately 40°C (104°F).

  • Correction
  • Using normal SPS reprogramming procedures, reprogram the LGM Liftgate module. The information was released on TIS version 2.75 or newer broadcast in March 2003.

  • There is a fuse block under the rear seat on the drivers side. Fuse # 3 and # ^ are the ones you will check for the Lift Gate.
  • Often the problem can be in the harness going to the module.
  • Sometimes the module needs replaced and then reprogrammed.

2002 trailblazer making loud humming noise when driving


When you turn right - you're taking weight off the right wheel.
If the noise dissipates - the passenger side wheel bearing is most likely to blame.
