You will get a better response posting this question in the General Help section.

It may be that the system simply needs re-charged. There is a switch on the high pressure line that will not allow the compressor to run if the system pressure is too low. I usually jump the switch connector momentarily -- if the compressor clutch engages then that is your problem. If not, the problem lies elsewhere in the system. If after re-charging the system leaks down again, you will need to have it dye tested.

Most likely the refrigerant has leaked out. If so, have recharged with fluorescent tracer dye at the same time. If its a slow leak, then take it back to the shop when in 200 to 500 miles to have it recheck the system for leaks with a black light.
