Default 2000 V6 Mustang AC Problem

I have replaced the following:
1) Low Pressure Switch
2) Accumulator
3) Compressor
4) freon

I have also checked the AC clutch wire for power which tested ok. My clutch is still not engaging.

When changing all these parts, did you have a shop pull vacuum on the system to recharge it with refrigerant or did you just use cans of r134a that you purchased?

Assuming that the controls work, there is sufficient pressure in the system, and your getting a 12v signal to the compressor, it should engage. Possibly your ccrm has a bad circuit on the A/C relay.

I used a vacuum on the A/C system before charging with A/C Pro 134A. Yesterday I jumped the compressor clutch so I could add the sufficient amount of freon. I am getting a new CCRM this afternoon. I am very convinced it's the CCRM because I had a diagnostic ran on the car last month which pulled a code for a faulty PCM. I ignored it at the time, but I suppose I will kill two birds with one stone by replacing the CCRM.
