So just purchased a 2002 ss with 120k. Car looks really nice for age and miles. I really liked the interior and there is little wear on anything. I made sure i checked everything over before purchasing the car and the sunroof was the only problem. It starts to go up on the right side and tries to go back. even the back left side tries to lift and go back but the front right corner sticks in and makes a weird clicking noise. The p/o kind of pushed it up and it opened but now i cant seem to open it. He gave me like 200 off for this reason but i would really like it fixed right. So any help. Does it just need to be greased or is that clicking the sound of a failing motor or striped gears?

 

My guess is its sticking at some point, creating it to hangup. It could be the gears in the motor stripped, or simply a slider getting hungup. Try to get it opened and grease the tracks and moving parts (white lithium works well). Make sure it closes right though, or water will leak in (going through that now with mine).
