My 94' 850 Wagon's A/C cuts out when I idle at a light or park. The car has a slow 134a leak, I tried to refill, but the car kept cutting out and not taking any 134a. Two questions. First, I had this cut out problem before and the dealer fixed it by replacing the a/c high pressure switch. Is this something I can do or will it require emptying and recharging? Second, if I can live with the a/c cutting out how can I refill the system with it cutting out?
Thanks

 

Does the cooling fan work?
