1989 Chrysler TC by Maserati. Just before I took the hardtop off, I lowered all four windows. After putting up the soft top, the rear windows didn't close. No clicking or humming sounds at all. [The rear (quarter) windows always take longer to close, and one side was slightly better (passenger) than the other, but they do fully close.] I wouldn't think it to be a motor problem, though I am not that knowledgeable on the subject. They opened as fast as always. Thank you in advance for any suggestions. Rick
