Re: Air Conditioning Issue.
Welcome to the garage.
Can it be that the air comes out of the windshield air outlets? You probably have the manual AC system, which uses engine vacuum for the mode door control. When vacuum is lost or not high enough, the air will go default to the windshield. If this is the problem, then you have to look for a leak in the vacuum hose coming from the engine inlet.
