My 1994 S-500 rear pass. window operates ok in normal or first detent mode. But in auto up the window stops around 2/3 up and then goes down slightly. I have tried resetting it according to the manual which says, push the up button and after the window closes hold the button for 2 seconds. This has not worked. I read a few other threads on similar problems and held the button for five seconds, both in the up direction and down direction. I also tried holding the button full down with same results. Does the fact that the window moves fine with the button held down to first pos. mean there is a calibration issue? Or could there be a component failure? The window move smoothly without binding or excessive noise when you put your ear to the door when raising it. The window also goes down in auto dn. fine. Car has only 11k miles.

Thanks to all

SINCE YOUR CAR IS A 140 CH. IT'S SAFE TO ASSUME THE REGULATOR IN QUESTION HAS BEEN REPLACED AT LEAST ONCE.
THE MOTOR/FEEDBACK POT. WERE PROBABLY INSTALLED OUT OF SYNC. WITH THE WINDOW POSITION.
REMOVE THE INNER PANEL,REMOVE THE MOTOR ASSY. AND OPERATE THE WIND. SWITCH BRIEFLY,REINSTALL THE MOTOR AND SEE IF IT WILL PROGRAM FOR ONE TOUCH OPERATION.
YOU MAY HAVE TO TRY THIS MORE THAN ONCE.
ALSO FORGOT TO MENTION WINDOW SWITCH HAS TO BE PLUGGED IN WHEN YOU DO THIS.
