Well it spins (free wheels) all the time but the clutch will engage and disengage, did you add oil to it when you added freion?

check your fuse or relay...could be a low/high pressure switch.

yea prob a low presure switch or something. check for power going to the ac compressor clutch when you try to engage the a/c. If not, then start checking the a/c pressure switches. You can even bypass a switch with a jumper wire to see if that switch is the cause.
