1987 porsche 944s a/c compressor turns off and on. When at idle does not cut out. when accelerating and under load will cut out. sometimes will come by on after around ten seconds and then cuts out again. pressures are fine and blows 39 degree air at idle. Replace pressure switch but not much difference.

i had the same problem. I sent the car to be checked out and turns out a hose under the engine had fallen out.

SOURCE: car stalls like there's no gas.but i have gas.

hi, fuse box is in engine bay, take off cover and relay has dme written on top, pump is at rear, underneath car, just below fuel tank, there maybe a large cover to take off first.

SOURCE: Air Conditioner blows very hot air

ASE mechanic here:
sounds like a mode door is stuck causing the air flow to go across the heater core only and not the evaporator. try activating the hot to cold functions to may be un stick the doors. if no changes then try a computer scanner, these new cars can have HVAC control codes and be accessed with a scanner, telling you the problem. if no access to that a good European shop is the next best thing. They might be cheaper than a Porsche dealer.

A small plastic retainer near the door handle often breaks. Can be accessed from inside the door panel. Cheap part, but pain in the a#% to replace.
