Yeah there's no jumping that sensor already looked into it. Ive heard the 3pin sensor on the line be called several different things.. A/C pressure switch, cycling switch, etc. I couldn't find anywhere on Mitchell to tell me what the correct voltage is for a good sensor. GM lists for $55 and my cost is only $22 so I'm just going to replace it first. I know the pcm turns the ac compressor relay on and off and I can see the relay command with the tech2 go from on to off but a/c shows no DTCs.
Seems like the compressor stays on for long duration in the morning for first startup but gets worse through out the day. Already tested the clutch.
