A/C Clutch Engagement
Pulling code PO640 Quad Driver1 or Quad Driver4. Just replaced entire A/C System. Compressor,
Dryer, New Pigtail to Compressor, Compressor Pressure Switch. Checked all switches high/low psi, a/c relay switch. Sounds like PCM or wiring harness. I NEED WIRING SCHEMATIC OF A/C system 95 SE ID K. FACTORY MANUAL JUST SHOWS BLOCK DIAGRAMS. Mr. Bill Buttermore any help would be appreciated.

Each quad driver in your year drives three soleniods. If you have the FSM, then you will have the most data possible.
Take a look at the three things on that driver and let us know what it has on it. Most likely it'* one of them. If not.. you do have the flakey pcm.
