My A/C does not work
The relay is ok.
The system has Refrigerant.
I did notice the clutch does not kick in to turn over the compresor
does this indicate the clutch is bad.
Any help is appresiated!
Thank you!

ANy break in the clutch circuit/control can cause this: out of details about the car year, this www.avigex.ca/xport/accompressorcontrol.jpg
is a typical Pontiac schematic : you see it includes pressure switches , a relay, and authority from the ECM....
Since you say the relay is good, may be you could make a direct bypass from that point to see if corrent flows through compressor clutch coil...or simply test it with an ohmmeter.

Check to make sure the low pressure sensor isn't damaged/disconnected. This will prevent the compressor from kicking on.
