Steve & Mike,

Thanks for responding.

I agree that the system needs to be properly diagnosed and I won't be taking any action until it's been done by the book.

I did read in the ACC manual that high presure on the low side and low presure on the high side was indicative of expansion valve failure while equal presure was a compressor failure.

I am curious about the over charge, because the problem began after he charged it. I was thinking my AC needed checking because the compressor would cut out when the engine got hot. Now that the fan clutch is fixed that problem is gone. I wish I had left the AC alone.

As you all said it seems that the only way to know is to check the system properly on both sides. Am I correct in assuming that if both sides are above the correct presure that the system is over charged and the expansion valve may be OK?
