The air con seemd fine until I took the car in to get cam belt changed - at the same time changed all the other belts. When I tried the air con, it whined like hell and eventually broke. Mechanic said it was likely that compressor was finished and I would need a new one. I thought that it can't have just gone like that, so for the sake of £4 and half hour of my time, ordered an air con belt and fitted it this morning. Switched air con on, cold air blowing nicely, a little bit of a rattle so checked the tension, seemed fine. So put everything back on and went for a spin - by the time I'd gone 100 yds down our drive, whole lot was whining and belt broke. I am still convinced that the compressor can't just have died. I am wondering if the pulley spindles may need replacing. I don't want to ask the mechanic because he will only give me the same answer again. So what do you guys think?

Cheers
