Its been happening a while but its been getting worse. Doesn't matter if my heat is on full blast but it decides when to turn on and when to turn off. My defrost and/or heater will go days at a time without working then will suddenly turn on while I'm driving. I thought it was the heater control head, but I plugged a different one in and it did the same thing.
have the same problem?
