air conditioning problem on camry

How do i check for that? Is it the same as a service bulletin that i found on this page?

Cloughed expansion valve! Check ALLDATA to see if there was a SSC (special service campaign) on that year's A/C. If so and it was never done they will replace the valve and refill with R12. I had a 90 4Rnr and a 93 Camry and both were covered FREE - $400 worth of work.

Yes thats it --- looks like it doesn't apply to 91 --- ha but does tp 92 & 93!

TSB Number Issue Date TSB Title 1.. SSCP01 JUN 93 Campaign - A/C Expansion Valve

I don't think the expansion valve was a problem on 91s...that started with the 92s.

However, old "O" rings in your A/C lines may be the problem. They eventually split with age and allow the freon to escape. I had to have new ones put in and the A/C recharged after about 6 years in my car, and just recently had to have it done again (now it's been twelve years). R-12 is expensive, tho'...a system recharge and installation of new O rings cost me about $120 at my local shop. But my A/C is now so cold I could freeze ice in my car.

I think you are right on the "O" ring problem. My 92 camry used to hold the freon for a summer; but now only a couple of weeks. My mechanic tried to fix the problem by changing the O rings (I don't think he used the correct O rings); but AC seemed getting worse since then. I will appreciate very much if you can let me know where you got your "O" rings. Thanks.
