#1118 of 1159 2003 Pontiac Grand Prix GT Can anyone help me with the following problems?
May 24, 2012 (8:29 am)
Approximately six months ago, I noticed that once my car started and the running lights were on, when I turned on the heater or defroster inside the car the running lights would go off. If I shut off the heater the lights came back on. This went on for the past 4 months until finally the defroster, heater, fan,the front seat heater, and air-conditioner don't work, the interior clock does not display the time and I have been reading the forum posted here on the Grand Prix problems. Has anyone reached a reason for these issues? I need to get it fixed, but I don't want to spend a fortune for a local mechanic to try this and that. The car runs well otherwise, can anyone help me and let me know what the best fix for this problem is?
