Hi - as above, I think the a/c on our Xsara Picasso has gone beely-up. Not only is it not cold, the engine does not 'rev up' when the a/c is turned on. We have not been putting it on every week to 'maintain the seals'. Anyone out there any sugestions as to what it could be and how expensive to fix?
Could just be the safety feature that does not let the compressor switch on due to low pressure in the system if your seals have gone with not using it properly.
