I'm not quite sure where to post this one as I don't find a specific category for AC problems. My dual ACs have been acting funny, on and off, but now they are persistent. I first had the problem of the compressor cutting out when driving in city traffic on a hot, humid day. Then it progressed to not cutting in after I stopped the engine for a few minutes on hot humid days. These would occur very infrequently over the past three summers. This summer, however, it has gotten to the point where it does it every time I shut the engine off to run into a store. The AC always comes back after I get the vehicle out of city speeds for a few minutes (say 45 mph for about 5miles). I took it to the dealer and they said it was probably just low on freon but later told me the compressor had a leak and for $1000 minimum they would replace it. They also said I should only expect to get 4-5 years out of a compressor. My 99 only has 71,000 miles on it so it's got far less wear than "normal". It will freeze you out like it always did but running around town in August in Alabama with intermittendt AC gets a little tough. I'm not totally convinced that this is not another electrical problem brought on by heating in the engine compartment and not simply the compressor because of the conditions under which it happens. Drop the humidity and temperature (like in May or September) and it doesn't do it. Every time it has failed always been in July and August! I have changed all the AC relays that I can find with no change. Any insight?
