Window Rolls down when I close the door/ AUTO up/down don't work
Cleaned my window motor because it was getting stuck down. Everything went pretty straight forward and put it all back together correctly. I go to do the window reset procedure and I complete it. I open the door to get out and the window cracks open like its supposed to, so I think all is well.
Then I close the door and the window rolls down almost all the way....WTF???
I test the Auto up/down function and auto down will roll it down about 5 inches and then stop. Auto up sounds like the motor engages for a moment and then changes its mind.
I've probably done the reset procedure 50 times the correct way last night to no avail. I thought maybe something is inhibiting it, so just to test it I did the reset procedure with a C-clamp on the door closed switch. Even though the door is open and nothing is blocking the window, as soon as I push the door closed switch, the window rolls down.
I've probably done the reset procedure 50 times in different ways (holding the reset switch down AND up....etc) that I could think of and nothing has worked.
I've researched that it might be the BCM but that doesnt make any sense because both windows would be acting up. The window motor works like a champ now so I know its not the motor...
It might be the regulator but I'm not sure what/where that is...
Anyone found a solution to this or have any ideas?
Edit: This is the drivers side window, the passenger side works fine. I also have the KP technologies window module but I've tried the reset with the module both plugged in and unplugged and its no different.
I just realized something...
Does anyone know if the window wire/cable has a coil spring or something that helps it roll the window up?
When I uninstalled the motor, the window was in the up position but then slid down....after I cleaned it I installed it while it was still in the down position, not to mention a couple turns of the motor without it connected to the window while i was testing it.
If there is a spring, could it be possible that the tension on the spring is fighting the motor causing it to think that theres something blocking the window and therefore rolling it down?
Nope...to answer my own question for anyone that cares, there's no spring on the cable coil....
went back into the door and took the entire motor apart....behind the round silver casing on the motor is a planetary gear set whose sole purpose is to translate the distance required to roll the window up into circular rotational distance about the circumference of the outer gear which presses an up limit switch when the window reaches the top of travel...
The window reset switch isn't even a switch, its just a little rubber piece that holds the outer planetary gear from spinning as the window travels down...
So the motor works fine, the gear set works fine, the uplimit switch works fine...so it can't be the motor....
I had the same problem like six months ago I took it to the dealership and they said a wire had simply come loose and they reconnected it and not problems since. Not sure if that is helpful hope that it is somehow. They only charged me the diagnostic fee since it was such a simple fix.
I checked what your problem was but none of my prongs were bent. I even put my switches into another friend's Z and his window worked perfectly. I switched my motor into his car though and his window started doing the same thing so I knew then it was the motor.
I proceeded to take the motor apart and as soon as I took the shaft out there were a bunch of broken magnet pieces stuck to it. Apparently there is a magnetic ring on the motor and a sensor on the outside of the case that I'm guessing counts how many turns it makes to know what position it's in.
I doubt I can find a new magnet the right size anywhere around so I guess I'm shelling out the money for a new motor. For anyone doing the window cleaning, be very careful, that magnetic ring is very fragile.
Well for what its worth the same thing is happening to me. I did the DIY clean thing on the drivers side and it worked perfectly for 4 months now back to the same thing. Slam the door to get it to go up.
UGH so for the passenger side did the DIY thing and the motor just wouldnt work so I replaced the motor with a new (reman) one from AutoZone or one of those. worked well for a while then the auto-up quit working. started doing the same thing it will bump down when it gets to the top! the motors eve re-manufactured are like 115 bucks or something. What to do?!?!?!
