Air Conditioning

Asked by Aug 29, 2007 at 03:05 PM about the 1994 Toyota 4Runner

Question type: Maintenance & Repair

My wife was driving 4runner home from school and car started to overheat.  The A/C system stopped blowing cold air at the same time.  She stopped and added water.  Restarted car and engine temp returned to normal however A/C is sporadic in operation.  Sometimes it blows cold air and sometimes it doesn't.  Any ideas? Help! We live in Hell, I mean Houston. Oh well temperature are about the same in both places.

Thanks in advance,

Hi BrianKF, I would suggest you have the compressor checked out. The overheating could've been caused by the ac clutch locking up and not allowing the waterpump to cool the engine block. When it starts going bad it will blow warm or hot air occassionally. Good luck!

There is most likely something wrong with the radiator. An A/C system in a car uses the radiator to cool the refrigerant lines of the condenser coil. I would think to check the fan. Are the fans on the radiator working? If thats not the problem, the condenser which is located just behind the grill of the vehicle in front of the radiator. You should be able to see clearly through the fins of the condenser coil. If it has a bunch of debris stuck in it or is caked with dirt and grease then that will block airflow causing the condenser and radiator to overheat. When the radiator can no longer hold coolant or gets overheated it will not be able to help cool the condenser at all. Which makes it blow hot air in the car.
