Confused about wiring / Window
2005 Evo 8
Okay.. Thanks for the look.
I have searched many forums and threads but no luck.
So my D/S Rear window stopped working. Tested the switch, with a multimeter and put it on a known working window and it was solid. The fuses were/are fine and the wiring looks to be fine. So I ordered a new motor/regulator assembly. Received the new part and I plugged it in to test it before installing.. It moved up for a second and then nothing. So I thought maybe the part was bad. I hooked it up to the P/S rear window plug and boom... it worked just fine. I then again plugged it into the D/S rear window plug and it did nothing again. I can feel it clicking and trying to work, but it wont turn. I then tried to make it go up or down with the Driver main switch and nothing. I could still feel and hear it trying to move... but it wont. I then unplugged the window motor, cussed a bit and then had a smoke. After smoking, I Came back to the car and tried it again for the hell of it and it went down but wont work anymore yet again. The motor is getting hot as hell.... bad ground? I have traced everything and looked for corrosion on all pins and connectors... Notta.. any ideas?

There appears to be a problem with load in that door. Either there is not enough current getting to the motor causing it to not move/stop or there is an obstruction that is making the job of moving the motor too hard.
I would check the wire harness from the B pillar to the door and see if there is any corrosion or damage since the ground is good and the parts work elsewhere.
I would also look at the tracks, pivot point and rollers in the mechanism to see if there is gunk or broken missing parts that would make the window harder to move. .

Yah your symptoms seem to point to a mechanical issue. If the motor is getting really hot and not moving it's probably stuck

The motor works but is the window regulator binding?

so basically it has to be a wiring issue.. maybe a bad ground? Could a bad switch in the master swith (driver switch) case an issue?
I am assuming this is why the original motor went bad, it was prolly fried.

These should help

So as you can see in the picture, there was a piece that was broken off one of the electrical connectors and was moving around inside the D/S passenger switch on the master switch. This would explain the random movement of the window and why the motor was getting hot. It would keep sending power to the up circuit and overhead it. This would also explain why I didn't catch it when I tested the switch and motor plug, I had rattled out and so I couldn't detect it. Without it completing the up circuit, the window would not work period. So a new switch and it will be fixed. Thank you all for your help! I have a thorough knowledge of the window system now lol.
