A/C compressor going???
Whenever the a/c compressor cycles on it makes a fairly loud ratcheting sound. When the ac/defrost is off the compressor is silent. The noise is only there when the ac/defrost is on and when the compressor cycles. In other words, the noise is there for 5 seconds, when the compressor cycles on. Then its silent until it cycles on again. Usually every ten seconds or so.
Is this a sign that the compressor is going?

Id vote for the compressor clutch (the outer part held in with a 8mm headed bolt) as well.. If the pressure drops to low the system will not turn the ac on. But the low presure switch could be bad as well. I believe rock auto has them around $45.

I ran an evac and charge cycle. It only had .06kg in the system! To say it was low is an understatement. It is suppose to have .96kg!
Anyway, I charged it to .96kg and all is well. No more noise and the compressor is now staying on instead of cycling every few seconds. I have to assume there is a leak somewhere in the system. I added some dye to find out.
Thanks guys, again, for your help. I love this site!!!
