u need to reset it or bypass it

Found this wiring info.

Not on something that old.

Take your car to your local parts store, and have the computer codes read. Check what the codes say is wrong, and you will have a start towards knowing what to fix. There are so many different things that could be wrong, that's why there are codes...

The temperature display on the rear view mirror my 2002 Trailblazer LT is either way incorrect - like obviously too high or too low - but mostly just shows "OC" all the time. Is this an expensive fix? Is this an easy fix that I could do myself? What do I need to replace and how

There is a clip on the side of the cable near the transmission shifter

It's been a while since I did one. First check the fuse. The n remove the knee bolster, Couple of screws at the bottom and pops of at the top. Remove the bezel screws under it. Look at the cluster, Could be 2 or 3 screws holding it the bezel there. Te bezel pretty much pops off from there. If it seems tight around the ash tray, pull the ash tray. There are 2 screws there. You have to have the key in the on position and pull down the column shifter to get the bezel out. There are 4 screws to remove the cluster. Unplug it and plug it back in, see if it starts working. If not, then you need to do some wire chasing. You'll need wiring schematics and pinouts for plugs. You could just replace the cluster. But I have never had to. Usually wiring/plugs. Once I replace a PCM.

What exactly is the problem? If a fuse keeps blowing, there is a short to ground somewhere in that circuit. It protects the wiring from burning up. If you need further help, I’m available over the phone at https://www.6ya.com/expert/michael_2496c4f07ad24453

Which window switch ? RT DOOR CB-circuit breaker , do you know what a circuit breaker is ? 25A (System power for right rear window) LT DOOR CB 25A (System power for left rear window The power window system will operate anytime the retained accessory power (RAP) system is active or when the ignition switch is in the ACCY or ON position. The DDM contains 4 power window switches which are integral components. Closing any of the normally open, rocker type switches provides the DDM with a request for power window operation. The switches for the 2 front windows have 3 positions Up, Down and Express Down, while the switches for the rear windows have only 2 positions, Up and Down. Each of these switches and their positions is a direct input into the DDM. Upon receiving a request for power window operation, the DDM, transmits a class 2 message indicating the switch and it's changed position. The PDM contains a single power window switch that is an integral component. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation. The switch for the front passenger window has 2 positions Up and Down. Each of these switch positions is a direct input to the PDM. The 2 rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows. However the BCM, upon receiving a class 2 message from the DDM, can control the set of relays which will activate the rear window motors. The power window system consists of the following components: ?€¢ Driver door module (DDM)

?€¢ Passenger door module (PDM)

?€¢ Body control module (BCM)

?€¢ LR power window switch

?€¢ RR power window switch

?€¢ Window up and window down relays in each of the rear passenger window switches

?€¢ Window lockout switch

?€¢ Reversible power window motors in each of the doors (circuit breaker protected)

?€¢ LT DOOR CB 25A (System power for left rear window)

?€¢ RT DOOR CB 25A (System power for right rear window)

If you not sure about any of this I suggest you take your vehicle to a ASE certified repair shop .

To what? Trailer? Girlfriend? (Sorry, couldn't resist) But really, what type of harness are you trying to hook up? What are you hooking it to?

Are the bulbs any good? Is the fuse good? Is the display getting power? Switch working? Roll up your sleeves and start checking.

Is the SERVICE 4WD indicator lit ? The SERVICE 4WD indicator is an integral part of the cluster and cannot be serviced separately. This lamp is used to inform the driver of the vehicle that a transfer case system malfunction. The SERVICE 4WD indicator is controlled by the transfer case shift control module via Class 2.
