My R57 convertible top is getting stuck right befor the top finishes going down all the way. I checked and the rear window is jamming against the rear trunk and the rear roll bar it seems like. It u]is sticking so hard it feels like the window will break when it stops moving and I go check the window by hand. Anyone else havecthis one before? I checked the two switches and I do not get any errors.

Did you ever figure out what it was? I am afraid mine is going to do that it gets so tight when closing all the way. It has actually closed if I hold the swtch and let it force the top down.
