#20 of 27 2007 Corolla AC issues? by m12wonder

Sep 03, 2008 (2:18 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 27 a/c problem by bgvss

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!

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?

I also have a 2005 Corolla (with 120,000 miles) and am having the exact same problem. I would appreciate it if you could let me know what you found was wrong with yours, and what the solution was. Thanks

And your refrigerant is up to specs. too? That would be the first place to start.

#25 of 27 04' Corrolla diverter problem? by t_kollman

Nov 09, 2012 (11:30 am)

2004 Toyota Corolla can't fully divert hot air to floor vents, some air still comes through the dash vents. As a result, my face roasts and my feet freeze in the winter. Any ideas on where to start? Thanks.

#26 of 27 2004 corolla vent changing select troubles by mike1956

Mar 10, 2013 (5:02 pm)

when I change the selector switch on dash from defrost to vent no matter which one it will not change at all, it always stays on the defrost vents, A/C works fine, nice and cold but I can't seem to be able to get the vents to change in order to get the air in my face or on my feet to cool the car, I'm not sure if the selector switch has a fuse or if one of my vent changing actuators went bad, anyone know the easiest way to check this out, thanks for all your help, have a great day.

You might have the car scanned to see if any HVAC trouble codes come up.
 
The actuator motor for the blend door is located (I'm just squinting at a diagram here) way up under the glove box area--up toward the windshield.
