The old compressor was bad put in. New one put vacuum o it and confirmed no leaks. Went to charge and it would only take a little bit cause new compressor clutch wouldn't engage what do I do jump relay to get compressor going to finish filling. Filling by 12 ounce can it would only take maybe 4 or 6 ounces Should I jump relay and get compressor going to finish filling.

Just more on first post i disconnected the ac compressor and just hooked up a light. The only way I could get the light to come on was to jump the relay. I Dont know alot about elec. Diagnosis so im not sure if this would work because of the pressure sensor if anyone knows please let me know ow.

Hi im nate new to forum. I have an 05 colorado 4cyl standard and the ac compressor clutch won't engage. Fuse is good, relay is good. If I take the relay out and jump across relay clutch engages. Does any one know why im not getting power there. I checked the pressure sensor switch 5v on 1 wire Good ground and when I check the last twire it beeps ground fast like beep beep. Etc if u have a power probe u can understand what im talking about. I tried to jump pressure switch but dont know if im doing it right Please help I cant afford to pay someone to chase wires and track it done.
