Celica Forums General Discussion Interior Heating fault

Got a question for u guys- having heater probs. Keep having to turn auto climate control up high to feel heat. When it starts blowing warm it then goes cold again so I turn up a degree and it gets warm again then starts to blow cold again and so on. Every time I turn it up it gets warm then cools again! Seems to stay hot if set at 25 deg. Any ideas?

Hey, welcome.

Hopefully someone who knows more than I do can help you out better. But I'll take a shot in the dark and say perhaps the thermometer or whatever measures cabin temperature is faulty? Like it reads that the heat blowing has met xx temperature so it goes cold?

Good luck though.
