Here's the situation. Just recently my heater stopped working in my '86 RX-7. Before it worked just fine and all of the logicon switches worked. Now, the temp control switch doesn't do anything, it just blows outside temp air in. I can hear the air mix motor move when I switch it on the controls, though. Another thing is that when my heat went out, the temp gauge started reading really low, like barely above the C.

Could it be the air mix motor not working, or possibly my thermostat opening up too much?


Thanks for any help.

 

Sounds like a thermostat issue. It may be stuck open.
