driver's side window in my 2006 R500 will not go up. there's no tension on the button when it's pulled, no motor noise, no grinding, nothing. All other windows work fine. Anyone know what this might be?
I suspect the switch is broken since you have no tension. You'll have to replace or see if you can remove and repair. If everything checks out, then the motor is faulty.
