TTRider Posted February 25, 2021 Share Posted February 25, 2021 Sorry if this is a previously-answered question, had a look with the search feature but whilst could find threads about resetting the stop positions or replacing the regulator, couldn't find the answer to this. My driver's side window is ignoring the top & bottom stop positions, if I let it the motor runs until the window is fully hard up or hard down, when it makes a godawful clattering noise as the motor is still running but the window can't move because it's fully up or down, so the teeth on the motor are jumping across the teeth on the regulator (and I've had it apart, the motor tooth plastic is obviously softer than the regulator, so the motor teeth are wearing-off, yeuch) Full history - 2010 Cayman 987.2 - last year, had to replace the regulator : window wouldn't raise or lower, clattering noise so had a look in the door and found the cable had frayed and snapped - so fitted new regulator which was easy enough following youtube videos, getting the door card off was the worst bit - all worked fine, window went up and down; obviously window memory had cleared so I used the reset feature of winding window fully up and fully down to its limits so it 'remembered' where the up & down stop positions are : great ! - all worked fine for 8 or 10 months : window dropped on opening door handle and raised on closing door just as it should, window went up and down using one-touch just as it should, it stopped at the bottom and at the top - but a few weeks ago, went out in car and then when getting back in and driving home was aware of 'window is open' wind noise so pushed button to one-touch raise it and sure enough wind noise stopped as window closed but then got the godawful clattering noise until I pushed button again to cancel the one-touch closing - now, when I open the door the window drops fully 1 1/2" but doesn't lift back up when I close the door - if I use the one-touch on the window in either up or down, the window moves but the motor doesn't stop running when the window hits its physical limits of open or closed, motor keeps running. godawful noise as teeth jump on motor vs regulator, until I hit switch again to cancel the one-touch - so I can open and close the window by manually nudging it up & down on the switch, not using one-touch; so car is useable but obviously this is a pain as I've forgotten to close the window that 1 1/2" a couple of times after parking, or have forgotten about it and allowed window to go down fully using one-touch. - and obviously every time the teeth jump, it's wearing them out - I've had it all apart again, taken glass and regulator fully out and refitted it all back again, couldn't see anything awry, but it's no different still does it - I can see that the teeth on the motor are being worn-off, as the plastic must be softer than the teeth on the regulator - and I even disconnected battery for half an hour to see if a reset would make any difference : it 'forgot' the positions on the passenger window and I had to reset them, but driver's door still doing this Any ideas ? Where are the sensors for the window stop positions, which should cut the motor when it hits the full-up and full-down positions : are they on the motor assembly itself ? thanks Link to comment Share on other sites More sharing options...
