Lucky13 Posted March 9, 2009 Posted March 9, 2009 Today in a 92 LS400 the AC suddenly ceased to blow cold and the light above the AC button started blinking. What could the problem be?
TexasLexus94 Posted March 10, 2009 Posted March 10, 2009 Sounds like you have a leak in the A/C system. Happened to me last fall. I live in Vegas, so A/C is imperative. I charged up the system with a leak sealer last fall-I use R134A in my 94LS, and I can buy a can at Wally World for 5 bucks. It has held through the winter-although I'm waiting for 2 months or so to see if it is going to last a while in our astounding heat. Your 1992 car might use freon, however, and that could be more of a problem. I'm afraid your wallet will be severely dented, especially since you live in Hotlanta, and need A/C. I used to charge up my old POS 1982 Camaro with freon in Houston every 2 months or so-don't think you can do that now, so you may have to break out the money. And don't go the the Dealer-Stealer-you will lose your kids inheritance...
SKperformance Posted March 10, 2009 Posted March 10, 2009 flashing ac light means compressor lock up , take it to someoe to have it checked.
stroker Posted March 10, 2009 Posted March 10, 2009 My 91 LS has been doing the same thing for about 2 years, not all the time but periodically. Still blows cold. All I do is press the A/C button a few times and it stops blinking.. Whats up with that? Today in a 92 LS400 the AC suddenly ceased to blow cold and the light above the AC button started blinking. What could the problem be?
