Thanks for the support guys. Wew would be happy to help you out. There is a good chance that it has nothing to do with the roof delaminating. It is more then likely the front guide pins squeeking and popping. There is a TSb out for the exact complaint and we have fixed a ton of them. Here is a copy of the TSB. Let me know if we can help you out.
