Two problems related to defogger heater have been reported for the 2003 GMC Yukon. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2003 GMC Yukon based on all problems reported for the 2003 Yukon.
The contact owns a 2003 GMC Yukon xl 1500. The contact started the vehicle, activated the heater, and closed the door. He stepped away from the vehicle and, upon returning, he noticed a five inch hole in the driver's side window and door and the glass shattered in his wife's face. The failure has only occurred once, but the contact believes it is a safety issue because a severe injury could have resulted. The current and failure mileages were 97,000.
The heater did not work. I did not realize that until in the highway. The outside temperature was 29 degrees (f). I would not have been able to defrost the windshield if it were needed (which could impair driving). I called on-star to diagnose the problem while I was driving and they determined there were problems in the system and suggest me to see the dealer. Later on in the same day, the heater worked (only on the driverã‚s side) after the car parked twice.
