I just cleaned up the rails, i got a bunch of "crap" off of them. and i had my friend sit in the car and close the sunroof and open (it only makes the noise when i'm opening it,sliding it back and you don't let go of the button right away when the sunroof itself acutally stops, or when you go to tilt the sunroof up while opening it, thats when it does it the most. But then while closing it it doesn't make the noise at all.) it while i sat in the trunk to see if it was the motor making the noise and it was. Does that mean i have to spend the $450 on a new one or does it need to be tightened or something? I'm praying i won't have to buy a new one. Please help.
