Re: Location of AC Fuse on 2000 Camry? [pktrrm] by wwest

There are two possibilities. The OAT, Outside Air Temperature, sensor is usually mounted on/near the front bumper just in front of the condensor/radiator "stack".
 
Open that connection and the OAT would seemingly go below freezing. The A/C is totally disabled if the OAT is near or below freezing.
 
The second possibilty is the refrigerant pressure switch. On my car it is mounted just below the passenger side front headlight. A poor or open connection there would most definitely cause your symptoms.

Camry A/C Problem by rtemple

I have an 06 Camry w/o climate control. A/C is blowing only warm air. The compressor is engaged and does not cycle on and off. A/C control knobs light up but when you turn the temperature knob counterclock wise ( colder) at about 10:00 position the knob light goes out?

Check the blower resistor, which is by the blower motor squirrel cage, passenger compartment.

Camry 05 -LE not cooling much by in_buddy

Hello Techs,
 
I recently bought used 05 Camry LE with 44k miles on it. I have little to none about car knowledge. I have noticed even if I run my AC on max for an hour it only makes temperature ok not cool. Does that sounds fine? I guess something is wrong. Can any of you please suggest what to troubleshoot and what could be wrong?
 
Thanks in advance.

No, that doesn't sound fine.
 
Take it to a shop to have them check your freon levels and pressures. They'll also check that your pressure switches are working correctly, turning your compressor on and off correctly.
 
Toyota dealership can do that, or a repair shop that handles air conditioners.
 
You may have a leak, which let your freon leak out and is now too low. They can also check for leaks.

Thanks a lot.
 
Couldn't that a AC filter issue? Just another thought by someone.
 
Thanks again for your technical advice.

The filter is not a credible cause of the problem. The instructions to replace it are in the owners manual, it's behind the glove compartment, takes about 5 minutes to put a new one in. Do it if you want.
 
You run it an hour on max recirculate and the vehicle isn't cold, you have some freon flow related problem. Get it to a shop who can diagnose and repair AC issues.
 
You need a set of gauges to get even a basic understanding of pressures, an understanding of the principles of freon gas to liquid to gas conversion, the effect of pressures and pressure differentials which effects flow through and orifice, and leak kits to do it right. Some make the mistake of just throwing a can of freon in, which can cause problems. You can actually overcharge the system, preventing the compressor from pulling down the lowside pressure low enough, which then prevents enough flow to provide enough cooling. There is a set of proper pressures (on both the low side and the high side), that need to be in the system for it to work correctly. It's not really a DYI'er.
