#19 of 22 A/C turning off and on in '93 Corolla by denver5357 Aug 07, 2008 (9:20 am)
The AC has been turning off now and then while running. What I mean by that is that the blowing air completely stops. I can the turn the A/C off for a bit and turn it on again and it works, at least for a while. But it will eventually stop blowing, period, even while on. Is this a compressor issue? Should I bother having it fixed? I think cars changed to a different refrigerant since '93 and I don't want to pay $500+ for this, but if it is a small thing I'd look at it. Advice is welcome. Thanks.
#20 of 22 2007 Corolla AC issues? by m12wonder Sep 03, 2008 (1:18 pm)
Hi. I bought my first new car last year. I'm not sure if it's because I expected more or if it's a real issue, but my AC doesn't seem to have much power. I've noticed a slight smell (not bad) coming thru the vents sometimes and when I have the AC on, it seems to fluctuate between cool (never cold) and lukewarm. I also feel like I have to have it on the 2nd setting to feel air moving. Anyone else experience similar AC issues?
#21 of 22 a/c problem by bgvss Apr 30, 2009 (6:32 pm)
i have 2004 corolla s with a/c problem.After driving for 20-30 min my a/c will intermittently stop blowing cold,it's still blows at same volume,but gradually get warmer.I went to toyota dealer to check the a/c.Everything check out fine except a a/c relay and they changed.This didn't fix my problem.Today I went back for second check and now they told me that my a/c expansion valve need to be replaced.  Do somebody know where is location of this a/c expansion valve and why is so expensive to replace it ?Also do you think I have to take a second opinion? Thank you! Replies to this message: Mr_Shiftright (May 01, 2009 8:21 am)

Replying to: bgvss (Apr 30, 2009 6:32 pm) Could be the expansion valve. This makes sense given your symptoms. Why is it expensive to fix? Well it isn't on all cars, but it could be in an inaccessible spot (often behind the glove box or buried under the dash) and you have to evacuate the entire AC system, dry it, replace the valve and refill. So the expense is mostly labor and refrigerant. The valve itself is probably well under $100 bucks. (just looked it up---it's $78 from the dealer but a whopping 6.4 hours of labor to replace it!!)   So what are they quoting you---something like $700--$800?
