Scion Tc Ac Condenser
Troubleshooting Common Scion TC A/C Condenser Problems
The Scion TC A/C condenser receives high pressure, hot refrigerant from the compressor, which is then cooled by the condenser. But if the A/C condenser is damaged, the entire A/C system will not work properly. Below are common A/C condenser problems and solutions that you need to know:
Frozen A/C condenser
The condenser isn't supposed to be cold, much more, frozen. So if it is covered with frost, suspect a problem. A good sign that the condenser may be frozen is when the A/C doesn't blow cool air in the car cabin. When this happens, step out of the vehicle and check the condenser. If there's ice around the condenser, suspect an internal blockage. The blockage is caused by dirt, oil, and other contaminants that have accumulated over time. What you need to do is to hose down the condenser to flush the debris or replace it with a new A/C condenser. Once the condenser is cleaned or replaced, the A/C should work normally.
Leaking or damaged A/C condenser
If the A/C condenser is punctured or damaged, the liquid inside the evaporator coil may leak and cause the A/C not to blow cool air. There are two ways to diagnose the problem. First is to use an electronic leak detector. Check the low-pressure service port by connecting the blue hose of the A/C gauge set and the high-pressure service port by connecting the red hose of the A/C gauge set. Refer to the service manual of your vehicle to check if there pressure reading is correct. Make sure that you understand and follow all the safety instructions when repairing the vehicle to prevent injury. The second way is to use a refrigerant leak detector dye. Pour one can of refrigerant with lead detector dye on the low-pressure side while the engine is running and the A/C at the highest setting. Drive the vehicle for 15 minutes, keeping the A/C at the "MAX." The leak should be visible as the traces of the dye flows out of the condenser. You may plug the leak if permanent fix is not yet possible, but make sure that you replace the damaged A/C condenser right away to prevent future problems.
