Temp sensor?
Faulty fan connector?
for that matter, if you remove the beauty panels near the hood latch, unbolt the top of the radiator and tip it toward the windshield (gently.) how filthy is it in there? My green car was rough after 140,000 miles.. cleaning the radiator made a huge difference..
I haven't hd a chance to check the fan connector but you guys may be right, when the heat pins I turn on MAX AC and it immediatly drops. By the way, where is the fan connector?
How would I clean mine out?
