Having similar problem along with the #5 position fan long time know about ignition switch.Part time air conditioning caused in my '98GTP by slamming door,hitting a bump,turning you name it. Most likely a bad ground or two under and forward. Bought this new for my wife and she loved it until the 20,000 mile dealership visit when the battery made contact with the radiator and fried the positive side bundle, transmission coolant line,radiator, battery etc. etc. I wanted it gone but she didn't so now with almost 100K I have assumed the pilot's seat along with the head mechanic's plot. Have had two water pumps, intake manifold, all brake fluid and gas lines replaced, front cv joints and axels, the coolant is brown again along with the trans fluid oh! I forgot to mention the first full detail had to be post poned till the dealership added more black paint to the right quarter pannel. ALL in all it is still a trip when you kick the floor like my very long'63 GP back in the south of Cal. Life goes on. blakprix
