Re: AC blowing hot air when off?
I dont suppose you have your hvac system on auto climate control when this happens do you? If so your inside air temp sensor reading may be causing your problem. It will default to -40c if its not working and try to heat up the cab

Re: AC blowing hot air when off?
It's always on auto - interesting! So how would I test if it's the sensor or the actuator?
