Question about 2002 Chevrolet TrailBlazer

2 Answers

Electrical My grandmother has an 02 Chevy Trailblazer, which the entire front passenger door doesn't work, ie. the door locks, window, mirror. We have taken it in and they said its not the connector inside the door and they would chase the problem but since she's on a fixed income it would be to much for her to afford. I told her I would see if maybe I could find the problem for her to save her the money. If you have any possible suggestions it would be greatly appreciated.

    I have the same issue but there is also a problem with controlling the door from the drivers side aswell. I also noticed when the door malfunctions the system that keeps the radio, lights etc...running when you cut the car off and take the key out does not work. These accessories shut off as soon as the key comes out but they are suppose to stay on until you open the door.

Passenger side windows, door locks, power mirror. on 2003 trailblazer dont work

The electrical functions on this car that you have mentioned are controlled by a module called the Body Control Module or BCM for short. Whenever a malfunction like this occurs you need to have the dealer or a well equipped shop hook up an electronic system scan tool, it will actively test the systems of the car and return fault codes indicating where to start the diagnosis of the electrical problem, in your case that can be the wiring to the door or the BCM is malfunctioning. I would be inclined to think the wiring is at fault here..

02 Trailblazer, 94,000 mile, Electrical problem. No power to passenger side door. Now no power at all: door locks,windows,mirror, instrumentation panel. All fuses appear good.

Whether it's a 52 or an 02, GM's have a problem - the wiring harness to the doors. Check the wiring in that funky vacuum cleaner hose-looking tube in the door jam, see if there's anything bare, broken, or otherwise screwed up. Best place to check for faults in this situation! Good luck!

This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.
