Well my windshield creaked today. Truck sets outside in the cold, about 14 degrees, had to scrape off ice and used some ice melt spray on it. Then cranked up the defroster and drove down the road. The creak starts from underneath the wiper in the black area on the drivers side and goes up the window about 9 inches. Asked the glass company installer on the phone what would of caused this? He said that he bets I had a chip in the black area and when I turned on the defroster it creaked the window (never used the defroster on this truck before, and won't again). He will check it out when I take it in to be replaced Thursday. I don't remember anything hitting the window. Going with Mopar OEM glass and this company has been doing this since 1947 and the dealer recommended them. Never had this happen before in 35 years of driving. Is this common with our trucks or am I just lucky and get to shellout $250. 00?
