AC only blows cold when driving. The moment I stop at light or stop sign it blows warm. System has been check by professional and has correct amount of freon with no leaks.

Are you really sure the fan comes on at all.....anytime? Normally, in the Camry and Avalon the fan does not run at highway speeds. The air-flow above 45-50 mph make it redundant anyway, and that air-flow alone that even makes the fan blades turn. There is no need to electrically power the fan at highway speeds. I have a feeling that it's the rpm of your engine, thus the rpm of the compressor, that is causing the A/C to not work so well at a stop. Yes, the fan should come on when car is stopped. No doubt, I am not disputing that. But even with the right amount of R134a if the compressor is not engaging or beginning to fail, just what you describe will happen,.It may be the thermostat in front of the evaporator also, the copper line. That must be clean. Check the fuse to make sure the fan works at all

The fan was never on the air passing thru the radiator while you were driving was turning the fan, its the sensor that turns on and off the fan or the fan motor is no good...

Cavity #38 in under hood PDC -- fuse box. See page 360 in your owners manual. If you don't have manual: http://www.toyota.com/t3Portal/document/om/OM33751U/pdf/sec_04-03.pdf -- Now Brandon, if you hear a fan at idle that cycles on and off that may be the regular engine/radiator fan. The Camry and Avalon have the dual fans...Corolla does not. The fan on left, drivers side, is for the engine/radiator. The one on right, passenger side is Aux, or A/C fan for condenser. Do neither of them run? The way it is set up, you may want to opt to just get a single..bigger fan.It will bolt right in and use same sender. Why Toyota did this dual fan get-up in the first place is over my pea-brain. Do you have the I4 2.5L or V6 3.5L?

I would suggest the following. Start this vehicle up COLD. AC off. Turn the AC on max. Go out and open hood. Is the AC Compressor running? How many fans are running? Let the engine run till it is fully warmed up. How many fans are running? Is the AC compressor running. Find the sight glass in this system. Usually located on the Receiver/Dryer. Look...what do you see? Clear? Foggy? Bubbles? The next step in the Diagnosis is to plug in a Scan Tool. Most good scan tools are able to turn these fans on and off. This check determines whether or not the computer is able to do so. Now that I have made this situation more complicated....then it may be.....well...this is how the diagnosis would likely proceed via an AC specialist.

I had my son elevate RPMS while I looked at fans. When pressing gas pedal in park the fan turns on and AC blows cold as soon it goes back to normal idle the fan turns off.

Ok....without equipment attached e.g. etc. sounds like you are low on refrigerant. Key question. When the engine is idling and the AC blows warm...is the compressor engaged? If NOT..my guess the computer is shutting the AC off because it sees low pressure. You rev the engine up which raises the presser enough to kick the compressor on, If the compressor is engaged at idle, the fan should be running and if the system has been properly evacuated and refilled...it should function as designed.

Well I had the same problem with my 95 Corolla, the problem was that when I went to the a/c place, the stupid guy probably didn't gas it up correctly, a lot of air was in the line instead of gas (it might be from too much gas instead of enough also) so I let someone else let all the air and little gas out, then I got 2 small cans of gas and put it in, then it worked, hope it works for you guys.

Brandon, were you ever able to get this issue resolved? I'm having the identical problem with my 2007 Camry LE. I'd be inclined to just go add some freon, but my problem started immediately after I replaced the fusible link, which was made necessary by a stupid mistake I made while replacing my alternator.

Swan song, did you ever figure this out? I had the alternator in my 2007 Camry LE replaced yesterday, and same problem. Mechanic is saying that one has nothing to do with the other. Kind of feel like I'm getting the runaround

Have a 2006-07 Camry access blowing warm air when idling/ went to Walmart bought a recharge hwith attached hose to check refigeent/ everything ok than read somewhere to replace air filter/ $10 at Walmart put it in works like a charm/ cold air all the time rims back where they should be

There is a great possibility there is too much refrigerant in the system. My 2008 RAV4 had this same issue where, while standing still, the radiator fans would turn off, and then the A/C would get warm, and once the radiator fans turned back on, the A/Cwould get cold again. I had a gauge on the system, and it showed the pressure was within the correct range, albeit toward the top. When I let refrigerant out (by putting a rag over the Hi Pressure valve and pressing it with a screw driver) the fans came on and stayed on. I added refrigerant and the problem came back, and I was able to get rid of it again by letting some out till the pressure was near the bottom of the "good" range. So far, the fans have been on now for fifteen mins, and it's freezing cold inside of the car.

System is low on R-134a. When the compressor is pumping quicker it will cool better but still not to spec, You likely have a slow leak somewhere in the system. Have the system tpped off and add a UV dye into the refrigerant. This way you'll spot the leak when you see dye along a system line or condenser.

Why does it frost up on the outside of a Toyota Camry Le uh lil at bottom of windshield when a/c is blowing in park

After replacing my alternator (for a different reason) I found revs were running too low in idle, below 500 RPM when they should be around 750RPM. This was impacting the performance of my AC when idling. After disconnecting or replacing battery the computer needs to relearn the idle RPMs. This is done simply by turning key to ACC, turn off, turn to ACC, turn on, ensure park break is engaged and place vehicle in drive, allow it to run for around 5mins.
