Hi, my name is Burt. I bought my daughter a 2009 GXP and have experience with leaking sunroofs, key fobs, and failure with window not going up when door is closed. As I am the "fleet" mechanic for the family's cars, hopefully I can help someone out. I'm about to get experience with replacing the HVAC vent door modulator with auto HVAC. Will share experience with anyone who has the same problem.
Regards to all.
