I could trip the relay by using the trigger power and chassis ground but not the ground through the PCM. I have some kind of wiring issue between the trigger and PCM or the PCM itself. That I haven't resolved yet but I temporarily wired the AC to be engaged when the ignition is on.
With respect to your pressures, you can't really tell much from the static pressure other than being undercharged or overcharged. you're static pressure seems awfully high. I think it's supposed to be like 60-70 psi. but that doesn't really have anything to do with your clutch not engaging.
In your video, did you jump the power on the relay? Is that what it looks like when it's "engaged"?
I did check my voltage at the coil on the compressor...there is 13.3v.
Agreed on the static pressures...really tells us nothing other than that the system does have pressure.
When I jump the relay, the video shows the clutch pulling in, but not fully engaging the compressor.
Upon further inspection of the compressor, I noticed that the pulley only rotates freely about 270 degrees before it stops moving. This tells me that the compressor is seized internally. I have a new one on the way.
I'll report any finding I have when I pull orifice tube out and pull the system apart.
