I'm stumped. I have a 96 Mystique with a 2.oL engine. Within the last couple of weeks, I've noticed my heat isn't working. There's a bit of warm air coming out of the heater, but not like it did last year. I also noticed that the temp gauge doesn't seem to move. When I punch it(accelerate), sometimes it starts working for a while and the heat comes on good. Can this problem be my thermostat? If anyone has any ideas, please let me know, Thanks.
