Question about 1996 Pontiac Sunfire
Ahhh it's winter and I'm having a heater problem!!! The heater has been losing intensity over the last week or two, and just stopped all together now! I ahve checked the fuses, no concerns there. None of the settings are giving out anything, and I can hear the hissing sound still when I switch between the settings. Any suggestions for this somewhat handy single mom!!! Thanks a million
I had this same problem 3 weeks ago.... i know someone who works for GM and this is a common problem with these cars. under your glove compartment where yout passanger feet will stretch to there is a dash plate, when you remove that look for a plug sticking down with 4 or 5 wires in it. Unplug the connector and there are two 5.5 mm (I think) screws. Not positive on the size. The one towards the front of firewall is tough to get, but that is your blowermoter resister, replace that an you should be fine...

Mine is doing the same, but for a different reason. if the first solution dosnt work, you may have to flush your system and replace the coolent. the prev owner of my car accidentaly put a different typ of coolent in with the coolent that was already in her. he mixed the green anti freeze with a red anti freeze... the two arnt the same and now my heat takes for ever on a cold start.
so if the problem keeps up try flushing the coolent, and rplacing it... if you dont know how then the garag should do it for like 50 $

Thermostat stuck open .the water cant heat up to full temp. may need to replace . easy way to check is to take the radiator cap off when its cold then with the car running wacth the flow it will be **** untill the water temp get hot in the motor then it should start flowing untill the cooler water will cause it to close again. and so forth it'll keep repeating this . but if the water flow is going as soon as u start the car then replace the stat.
