Im having trouble with my sunroof. It wolnt open and close. It just vents for a second and then closes. Ive tried resync with no luck. I was wondering if you have heard of this problem and if so is their a cost effiecient solution. Ive been tossing up the idea of manual winding it open and tyring to resync with it open. But im very tenative to do this because thing are so expensive to replace. I have a 01 c240. thanks
