Usually by 150,000 miles the AC system will need some attention, especially in climates where it is used often. Our technicians tell us that it is best to service the AC system every 2-3 years. This keeps the moisture in the system at a minimum which extends the life of the components.Google+

Toyota Celica Problem
Visitor, 1994 Toyota Celica, 125,500 mi
I bought my 1994 Celica GT used. I got it with 123,000 miles on it and the AC seemed to work ok when I bought it. But then I started that when I turned the AC on that the car would idle too low and sometimes stall at stoplights. Then when I turned it on I smelled the compressor burning up. I had the compressor replaced. No more burning ,but the car still idle way too low with the AC on. I think I have narrowed it down to an AC-idle up valve,VSV, or maybe the EGR. Also, when the AC is on, the coolant overflows . I am assuming that I need to flush or replace the radiator or get a new condenser fan. I am in South Florida so the AC is pretty important.

My fan is not working for air or heat and the indicator lights went out also at the same time.
