Having problems with your 2003 Pontiac Grand Prix ?
2003 grand prix gt heater is not blowing out any heat. When the heater does start the lights go out. This car only has 50,000 miles on it. The heater has off, 1,2, 3, 4, and a 5 to put the blower on. The blower was working on speed 5 but now has quit also. My nephew who is a mechanic for the county seems to think the wires need cleaned. Is this correct?
