my problem start with the following, when i press the fuel and increase the speed of the car, the AC air comes off, then when the speed become stable, the Air return to come again.
i had replaced the back air valve in the air tube, then that problem had been solved but, the increase of the engine heat problem comes up, when i turn the AC on, then i changed the white relay in the relay box which is responsible for the control, of the fans speed, the small and the big one.
but i'm still have the heat problem.
