Default Air Conditioning only works on MAX - wheezing...

Hi All,

Did some searching over the last day or two -- after having my car in the shop for some routine work (fuel filter, valve cover gaskets, etc) - I picked it up and the AC now only works on MAX. If I put it on normal, I get a very, very small amount of cold air, and a wheezey noise (noise also present when AC is on MAX). If I turn the fan all the way up on NORM, it still does not blow cold - only when I press MAX.

Most of the AC problems I see posted have consistent behavior between NORM and MAX, so I though I'd post and see what everyone thinks.

cheers,

sean

The max button also puts the recirc on. See if normal ac with the recircon gives you more air. If so a GUESS might be a vacuum line off.

You probably have a non-working HVAC servo or two. I would guess the fresh air servo for starters. See here for tips on this: www.porschehvac.bergvill.com
