#2 of 4 Pontiac Sunfire Heater issues
Mar 24, 2010 (3:17 pm)
My 2000 Sunfire heater has only worked on #4 & #5 settings for the past 2 years. Rear defrost all of sudden stopped and now my heater is not working. I found a blown fuse and replaced it but it still blows. Disconnected blower fan and union and fuse still blows. Went to bone yard and replaced the heater switch and the fuse still blows (without being connected to the blower yet). What can I do? I dont know where to start tracing this short. We found melted wires for the rear defrost and replaced the wiring but this did not fix the heater issues.
#3 of 4 2002 Sunfire A/C electrical problem
Jun 26, 2010 (5:33 pm)
My granddaughter bought my 2002 Sunfire 6 months ago. Yesterday her A/C stopped cooling. The compressor does not kick in. The shop says it is an electrical problem, but they could not isolate it today in the hour my granddaughter had to wait.
Has anyone else had this type of problem?
#4 of 4 Poniac Sunfire Overheating Problems
Sep 03, 2013 (5:29 pm)
I have a 2000 Ponicac Sunfire. It just hit 75,000 miles and has begun having issues. It overheats if I run the A/C at all and if I drive for too long. Also, when the A/C is running the engine revs itself when it is idling. I was thinking it could possibly be the radiator or the water pump, but nothing is leaking and I can't seem to find the issue. And I won't even get started on the brake problems! Any tips or thoughts would be greatly appreciated.
