The rear left window does not operate. I checked out the motor and regulator and both are in working order. Can the next course of action be the module or is there a separate fuse. All the other window work correctly.

well i have 3 windows that are currently not working... and the motor or regulators are still working......

you very possibly broke the 1 and only PLASTIC piece that CADILLAC uses on the window assembly...

which is the LITTLE plastic piece that is on the regulator that SUPPORST the weight of the window on the SCISSOR... thats what broke in mine but you can still hear the clicking and the motor working....


ONLY FIX = ether removing the broken plastic piece and building your own braket and riviting it back to the old regulator... OR.... buy a whole new regulator with another plastic piece... and ether (A) install your self which can be VERY time consuming and you can mess alot of things up if you dont know what your doing or..... (B).... pay the dealership the 500 they want for each window... ITS BS.... but its there way of making more money

Thanks origanalitykills but the regular is working as it should. The problem seems to be electrical. I had the regulator out and tested it both mechanically and the motor.

The reason I asked if the window was up or down is because I thought that if the plastic part that origanalitykills talks about was broken, I thought the window would fall and not raise. If that is the case, there is a tutorial in the Tech Tips section to repair that. If that is not the case, then I would ask if the window is inoperative from both the window switch AND the master drivers switch or just the rear switch, in which case the problem would be in the rear switch.

There is a better alternative: fix the flimsy plastic part with cotter pins. Easy, quick, and almost zero cost. See Eli Ice's detailed photos at this link post #10:

A number of us have used this clever cotter pin fix & it works & it lasts.

Ranger, The window will not operate with either the driver control or the rear door switch. Door locks work from both locations. The motor clicks but will not rotate while it is installed in the door. I can operate the motor and the regulator on the test bench

70cougar, I know about the clever cotter pin fix but this is not the problem. I believe it to be electrical. Thanks for your suggestion

Sounds like it's getting power. Have you checked to see if something is binding? That's all I can think of.

Remove the motor from the regulator and see if the door switches will drive the motor.

One of the wires leading to the motor might be pinched somewhere in the door. I had this same problem with my '01. Try opening the door all the way and rolling the window down. If it works that way, chances are one or more of your wires are pinched. I want to say it cost a little over $100 to have it fixed.

Have you found a solution to your problem, I have the same exact symptoms, and when I checked the voltage it only read 7 volts coming to the motor. The other side gets 12 volts.

I found the problem. It is a broken wire in the rear door connector where all the wires come from the front almost at the swing point. They used a large guage wire that is not very flexible, with the door opening and closing apparently it breaks. Hope this can help someone.
