2003 Chevy Malibu 6 cyl Two Wheel Drive Automatic 90000 miles
The sunroof on this vehicle operates in the tilt and close position but only sporadically in the auto open position. When opening the sunroof stops several times as it reverses on the track. Each time having to push the open switch to inch it back. The track was cleaned and greased with a lithium grease and the problem still persists. Would root cause most likely be a controller or motor with these symptoms? And how easy is it to replace? Does the entire headliner have to be removed? Any tips on doing this?
