Hi. The AC in my Xsara Picasso blows hot air. The AC was checked and works fine, the specialist said it's an electrical problem. It happened twice before in 18 months, the first time it was fixed working underneeth the dash and the second was "accidentally" fixed while the electrician was working on the fuse box underneeth the hood.

I would like to solve it for good, and don't seem to find an expert not from the official service, which would cost a fortune.

Many thanks.
