Air conditioning not working

[tomazzo]

Discovered my air conditioning is not working...found that the compressor clutch is not engaging because the pulley spins, but the center of the compressor does not. Ive checked the fuses the users manual says controls the ac clutch, all good.

Can someone tell me what voltages I should see at the compressor, or what to check?

Thanks,

It may just be low on freon. Jump the low pressure switch at the accumulator and see if it turns on the compressor. If it does you are low on freon.

How about just converting 134a spec if you've got to work on the a/c system anyhow?

I would try what PRO50SC suggested that will tell you it is either just low on freon which is probably what the problem is or your low pressure switch is bad.
