I just had the A/C recharged at a shop. The A/C system had been empty since May 2009 when I had my new engine put in. Before then it worked great. Now I have codes 67 (A/C refrigerant pressure sensor circuit (pressure sensor or A/C clutch circuit problem)) and 69 (A/C clutch circuit) and the compressor will not engage. These codes did not exist before I had my A/C recharged. The mechanics already left for the 3 day weekend so I'm on my own until Tuesday. Does anyone know what could be wrong?

Try resetting the PCM and clearing the codes.

Yes, first thing clear codes.

Cleared the codes. When I started the car they were gone. As soon as I turned on the A/C, code 67 came back and the compressor did not engage.

That tells you right where you need to be looking.

I also forgot to mention the fans turn on as they're supposed to when I try and turn on the A/C. So is it just a matter of making sure all the wires and connections are good? I did a quick glance and the pigtail is plugged in on the compressor. Any wires or connections in the interior I should check?

yea im having this issue too only i have not run for error codes yet. my ac is blowing out hot air, replaced compressor, new one still wont engage but fan kicks on. so me and him might be having same problem

I took a closer look at the pigtail on the compressor. There are two wires going to the compressor: a black one and a green one. The green one is cut flush with the pigtail. I'm guessing that's my issue? Not sure how that could've happened.

For closure purposes: after ordering a new pig tail and soldering it on, the A/C works like a charm.
