My 2000 camry air conditioning air sometimes gets hot

My 2000 camry air conditioning sometimes stops putting out cold air. Blower just puts out hot air. I need to let it rest, like overnight, before it works again. What's happening?

    Thanks Bad_Dog1,



    Just to let others know. I did added freon when the problem first showed itself. I used one of those bottles that has a pressure guage. My guess is that I did it right. Air runs perfect except when it suddenly quits. After it failed again, I switched relay switches with the clutch relay. I am now waiting to see if that does it. Next I am going to do what Bad_Dog1 says. Check for line freezing which I have not not a thorough job of, and then find where the "pressure switch" on a 2000 Camry is. Thanks, Bad_Dog1.

There are a couple of things things that could cause this. The first thing i would check is your refrigerant level. Low refrigerant would cause your compressor to turn off. The next thing i would check is a restriction in your A/C lines. A restriction would cause a pressure difference allowing ice to build up in side your A/C lines and not allowing your refrigerant to cycle normally, and of course once the ice melted your a/c will work again.

    another thing you might want to look into is your pressure switch. If that is not working your compressor will go into a fail safe mode and stop working.

    Hello Bill,

    I was doing some research and found out that you pressure switch is located just before your condenser behind your front bumper. Hope this helps.

How do I clean air vents in 2000 Toyota Camry


If your talking about the a/c and heater vents basically put a vacuum cleaner in front of them. The same holds for blower motor intake ports. First clean debris from under wipers by hand then vacuum.
Lastly the a/c evaporator hose should be drain and cleaned. basically get under vehicle with eye protection and use a tongue depressor to clear the hose of debris. Be careful cold water will pour out and be gentle with deopressor no need to go deep into hose you can puncture evaporator. Thats big money$$$$$$.

How to troubleshoot the electrical air conditioning system 2000 GMC Yukon Denali. I put in new resistor, relay and dealer blower motor and it still doesn't do anything. Air conditioning control switch...


The compressor on the air conditioner in my 2000 GMC Yukon XL went out last summer. Had it and the whole line replaced at a local air conditioning shop last fall. Used it little before cold weather. Warm weather this spring and no cold air. We could hear the compressor trying to kick in. The shop told us that the control console was bad and had to be replaced. They told us the part was on back order and did not know if they would be abel to get one any time soon. We took the Yukon into the local GM dealership. They told us that the high side fitting was bad and that the freon was very low and that they would have to deal with that first to check the system. Called back to the air conditioning shop and they said they had a console come in and they would put it in and check the high side fitting. I now have cold air and questions. Bought Yukon in 2005 used, had always had problem of not switching to cold air once the heater has been used. We were told changing the console should fix that. It has not changed. I feel like the console angle was a scam, that the system was just low on freon. Each shop was blaming the other for trying to scam me. And what can fix the heat to cold issue? If anyone has answers I would sure appreciate the knowledge.

Heater stopped putting out heat, blower works fine air conditioning works fine


What you are saying is when you turn knob to hot you don't get any heat.? Let's start with the basics. Make sure your cooling system is filled up with coolant. Then with the engine warmedup and the temp gauge on the dash indicating between H and C. Find your heater hoses under the hood and feel them. Are they BOTH very warm or hot? os is only 1 warm and the other cool? If both are warm/hot, and still not getting heat from your vents. You have a problem with either the temp controller or the blends doors under the dash. usually the blend doors and it requires removal of the dashboard to get to it. If the heater hoses are wrm and cold then you may have a plugged heater core or water pump not circulating properly.

Ford ka heater blows hot air all the time


Your problem is a faulty heater control valve. The design used on these vehicles allows for hot water to flow constantly and compete with the evaporator as there is no blender door. You have to replace the valve and possibly the control head. Meanwhile, you can bypass the valve to have cold air

1993 Jeep Cherokee blower/Heater Issue


Your blower motor could be "clogged" but I never saw one with enough debris in there to actually make one stop/ The cure for both is to remove the blower motor from the air box. if you find tons of leaves in there, clean them out. If the shaft on the motor has lots of side play, or will not run when connected hot to battery, replace it.

I have a 2000 dodge caravan, no heat


Sounds like the air "blend" door might be inoperable. This door opens and closes a specified amount to regulate the amount of either cooled or heated air, as requested by the climate control unit. If the door is continually in the position which is bypassing the heater core (cold setting), the air will not get warm regardless of the condition/operation of the heater core. I'd suggest having this component checked.
