Today have noticed another strange thingh about my hvac unit. I put the car out of the garage ant let it at idle just not to turn the engine on and off just a while after. The engine ran for about 20 min and the for all the time the car ran ac was working great. Then I decided to go for a small ride and, surprisingly, the ac got off after few meters driving.
Is this still relating to the head unit malfunction or have I to point in another direction?
