Okay, I have a problem with my sunroof-it' not leaking, but it sticks and when I try to open it, it opens a little, then I have to push it pretty hard with my hand, and then it opens a little more, and then I have to push it again. It seems as if it gets stuck on something in there. I have done numerous searches. Some said to regrease the tracks, which I have done 10 times and it still doesnt' work. And all the other searches pointed out that most likely it's the motor-although the motor sounds strong-it just seems as if it gets stuck on certain opening intervals. So my question is, is how do I get to the motor in my sunroof?I want to replace it, but really have no idea how to get to it. I hope I don't have to cut into my headliner. Oh well, any help is much appreciated. Thanks.
