I replaced accumulator dryer, compressor,constant control relay module on 1997 Ford Taurus

The compressor will not cycle, will not turn on. Any suggestions?

Call Dublin Auto Repair and have them check the relay, fuse, pressure switches and to see if the system has R134a in it. (925)828-0243
Thanks, Hal. The system was discharged into an approved container, and then charged with R134a.
I'll be calling Dublin Auto Repair to have the relay, fuse and pressure switches checked. Thanks again.
