Air conditioner compressor seems to quit after 1 to 2 hours driving-blower stll runs, but cold air stops green compressor lite is still on, but no cold air-turn off ac for 20 to 30 minutus, comes back on cold as ice, but seems to quit again in a shorter amount of time-worse in hot weather-the hotter it is, the quicker it cuts out -toyota checked and could find no apparent reason about 3 years ago- please help

Look to see that the A/C condensate drains are working. You should see water dripping out from the front & the back whilst the A/C is running. If no water; clean the drain tubes. Also, you need to be running the A/C on the RECIRC mode (the little car with an arrow doing a u-turn inside the car); if not, you are air conditioning outside air, and the unit is icing up from too much humidity. Sort of like running your fridge with the door open...
If neither of those items correct your issue, you may need to replace the A/C thermister; but, that is a very rare failure.

Please take the car for diagnosis and the revealed codes will definately lead u ahead.

See that your AC condenser is not dirt blocked too.

Cheers.

I would bet that your fan is not coming on. When an airconditioner is on it uses alot of power and that makes heat. The engine will warm past the safe point. Most vehicles should have a switch that turns the fan on and off to cool the motor. You can start the vehicle and pop the hood. once it gets warm if you don't see the fan come on that's most likely your problem. Be very careful around the blade because they come on and off suddenly. I go to Auto Zone for free diagnostics. They only sell parts but can walk you thru possibly fixing it yourself.

are the cooling fans running when ac is on ?if not this is ur problem,,,if they are on then u have a temp door in the ac duct system that is closing if it is an actuator motor u will have to replace it ,if it is vacuum,check for a bad vacuum check valve or bad vacuum hose near fire wall(near windsheild)
