Default 2002 Boxster S air conditioner not working:(

I just bought a 2002 Boxster S and I LOVE IT, but the air conditioner is not working. I took it for a free AC check and it was found to have plenty of freon. Has anyone had experience with this kind of problem before i take it in to a mechanic? Im trying to research and find out about relays etc.. that would make it go bad. Any help would be appreciated. It has the auto climate control and everything blows as it should, it simply doesnt blow cold. thanks in advance and i look forward to making a lot of friends here. jonathan

Sorry to state the obvious, but did you check the fuse box?

I think it is in location E-7. Bottom row (E), 7th in. 7.5amp.

There is also an AC Compressor relay in the rear truck panel.

Congrats and welcome to Rennlist!

i have the same issue in my 1999 and i've yet to resolve it. the compressor is good & freon level is fine. the coil is COLD, but for some reason, the cold air never gets to the vents.

If some air coming out of the vents, in your car's case I suspect the air flap that controls the air flow through the A/C evaporator is not working and incoming air is not being directed to flow the A/C evaporator and thus is not cooled.

If you have an auto climate system the Porsche diagnostics computer can query the autoclimate control for diagnostics info that can help a tech trouble-shoot the problem. (I wouldn't be surprised that they have encountered this already and know just from the symptoms what's wrong.)

If you have a manual system you might be able to fool with the controls and by listening hear, or fail to hear, the various flaps being moved. They are usually quiet, but the mechanism that moves them can make some noise.

I've only had autoclimate control systems in my Porsches and have no direct experience with the manual systems, but if the manual system uses direct mechanical linkage to the flaps (and I think it does) -- then rapid movement of the temperature control **** may help identify the problem by not making any noise cause the control is not moving the flap as it should or perhaps by making some odd noise cause the linkage is broken/loose and all you hear is the linkage flopping about as you move the ****.

Sincerely,

Macster.

As macster said, it could be a flap not moving doe to a faulty cable or clip. Seen it happen in many other cars.

i figured mine was a flap malfunction (i do have the autoclimate). my next step will be to swap out the climatronic unit for a known good one to see if that solves the problem.

Had a problem with my 01 turbo not blowing cold also. Dealer replaced the ignition switch and the problem was solved.

I've replaced compressor, dryer, expansion valve and HP switch, have plenty of freon but won't come on unless I jump the relay. Oh, new relay and fuse checks good. If it's the LP switch, where is that? Looked at ign switch pricing, hate to spend that much and it still not work, how can I test it? Thanks! James
