Welcome to the forum Darrell. At the pressure switch see if you have 12V on pin 1 (PK/LB) and 3 (R/Y) wires and 0V on pins 2 ((BK) and 4 (T/LG) with the engine running. If these check out then the two other components that determine if the compressor clutch is engaged are the PCM and Constant Control Relay Module (CCRM). The CCRM is located between the air box and the radiator support and has a 24 contact pin connector. One side has contacts 1 - 12 and the other side has 13 - 24. The PK/LB wire from the pressure switch goes to pin 21 on the CCRM so see if you have 12V at this point also. Pin 23 (BK/Y) is the output of the CCRM to the AC clutch and should have 12V. If it does then you have a bad connection between the CCRM and the AC clutch. Let me know what voltage you get on pin 22 (PK/Y) of the CCRM. With the engine OFF and using an ohmmeter, see if there is very close (< 0.3) ohms from the AC clutch wire (GY/W) and a good ground connection. This is the return path for the AC clutch. If the answer is no then there is a bad connection between the AC clutch and the CCRM pin 16 (GR/W). When you jumpered the AC clutch did you just connect 12V to it or 12V and a return wire? Was it still connected or did you have the connectors unplugged?
