98 windstar A C problem
Hey guys, my 98 windstar A C blows hot air and the Clutch clicks in and out. I checked the system for Freon and its fully charged. What could be the problem? Is there a inexpensive fix? thanks

How often does the clutch cycle? You say it is fully charged... What are the pressures while the clutch is running?

OK..........Now we know the low side pressures..........Now what are the HIGH side pressures???????..........High side should be reading @200-240 psi depending on ambient temp.
If your high side is hitting those numbers and the low side drops to 20 psi and the low pressure switch does its job and shuts down the compressor, you have a blockage at the orifice tube...........
If the High side does not read those pressures then you are NOT fully charged

So I assume you are unable to check the high side pressure? Generally the low side pressure should be between 30-40psi when the compressor is running. When the compressor is not running the pressure should be somewhere near 100psi. If the pressure is dropping like you say it is then you have problems.
