Car Air Conditioning Repair : Compressor Problems with a Car Air Conditioner

Hi, my name is Mark Delgado with American
Auto Service for Expert Village. The compressors can have problems with the
electrical devices that turn the clutch on. A lot of times you’ll hear the clutch kick
on when the air conditioning clicks on and off. There are pressure switches throughout
the system. There is a low pressure cutoff and a high pressure cutoff and on most late
model vehicles, they are controlled by the computer that controls everything in the car.
It will look at those sensors and the computer will determine whether to turn the air conditioner
clutch on and off. Another problem is there is a sealed unit in the front that you cannot
see that can leak. There is a big O ring around it that can leak and there is a seal there
and then there are two seals on top where the line assembly that goes on. There are
a lot of different points where leaks can occur that would require removing and repairing
or replacing.
