No, you have to adjust the temp before turning off the fan or you wont be able to adjust it. I guess in hindsight it's always been that way. The vent temps have always been reliant on the temp setting regardless.

Well I just tried my fog light relay. That didn't work. I looked at my sight glass today...no bubbles. I'm beginning to think my AC is just jacked. I think I'm just going to have to buy those refrigerant gauges. Will the one that comes on top off of the h-134a cans be enough? Or do I need to buy both HI and Lo gauges? WHats the difference?

Thanks!

Update! I know many of you haven't been sleeping good since I've left you with a cliffhanger on my AC situation... so I'd figure I'd put your minds at ease...with some bad news.


I bought instant-temp thermometer, and a pencil-gauge for my ac LOW side AC. The refrigerent level looks to be right in the middle of where it should be...so that is good. WIth my AC at full blast after a few minuted my air coming out of the right driver vent is at 30degress F. WHen I put it on auto lets say at '67', my thermometer is almost exactly at that point. Auto regulates the temp very well...however when I switch to manual, the air quickly turns to about 100 degrees still at '67'. That is Effin ridiculous. WHen I set it at HI, my air was blowing 120 degrees F. It was getting a bit too warm so I put auto back on.

So...my question is what now? Toyota didn't want to help me out.

I spent WAY TOO much of my hard earned money to be forced to leave my car on auto for life.

When its on Auto, the air sometimes blows at my feet, but I want it at my face. ANd more often than not my winshield will fog on Auto.

Leaving it on auto to stay cool is fine for now, but when the summer comes...its not going to cut it. I want my AC to work on manual!

Any ideas...cause I'm freakin stumped? I almost feel like shelling out the 50 bucks for the new relay even though I tried my fog relay and nothing changed.

Mine did the same thing. I got my replacement m/t clutch relay from Advanced Auto for $13 bucks, factory air I believe. Replaced it and works great! PM me if you want the part number.

I hear you on that.., the heater is way too warm/hot, like you said it is all or nothing.... does running on auto help this rather than just trying to set the temp and the fan speed? Seems like the heater is too hot, and the AC is not cold enough, again, does auto help this?

I have an 03 V-8 with 77K miles. The AC light does not flash yet, but thinking of replacing that relay to see if that will help with the AC.
