AC failure


Recommended Posts

My ac is out on my 92 STS. Got the low warning for awhile then the ac off message recently. I also have a 1990 Eldo whose ac failed in the same way. Whats the common cause of ac failures on these caddys? Compressor seal or hose leak?

On a car that old it might not be a "failure". My understanding is that refrigerant molicules are very very small and can seep out of the tiniest if spaces. Over 10 yrs or more it is not uncommon to need to top it off. Just add a can and it will probably be fine for another 10 years. If it leaks out in a season, then you have a problem.
