I have a '99 ls and the sunroof is stuck closed. The motor is working and lifts the the sunroof about quarter of an inch but then stops. I can close it all the way down again with with the motor as well. I tried opening it manually but it got stuck at the same part. I've even tried pushing on it while trying to open it and no luck. I just got this car about 3 months ago and cleaned out the track and regreased and it worked great until the last month or month and a half. Please, if anyone has any suggests i am totally open. Thanks!
