The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.
1999 GMC Jimmy QuestionsHow do I know if my fuel pump is affected? (1 answer)
Anytime I drive, it does not seem to hold gas in the tank. It always seems I have to keep going to the gas station. I'm not sure if my fuel pump is causing the problem
When I turn the wheel to the left, I hear a knocking sound that seems to come from the front wheel.
I also hear a thumping noise when driving like a broken belt in one of the tires, but was told that it might be the wheel bearings.
