Over the weekend I discovered that the rarely used front passenger's window makes a consistent, continuous, low-pitch grunting noise while being raised up. You know like the motor is about to give up. It hasn't slowed down compared to the driver's window. Any ideas? As always, thanks a lot for your time.
Perhaps the window track is binding where the window attachment slides along, some good lubricating spray may help, not sure exactly which one. It hasn't slowed down compared to the driver's window. It would make more sense it was slower than the drivers side.
