Hi I have not scan the car, yes I did a vacuum for 20 minutes after replace the mentioned. Parts and istar filling with freon but the ac clutch not engaging neither the fans come on

Expert:  -Brad- replied 1 year ago.

What engine do you have so I can get a wiring diagram?

Customer: replied 1 year ago.

2.7liter the old compressor did engage but the car wouldn't take the freon so a just answer exper recommended changin expansion valve after than with no luch he suggested I need drier and new compressor

Expert:  -Brad- replied 1 year ago.

I attached the wiring.. This issue will be hard to diagnose without a scantool because the TIPM which is the fusebox under the hood controls the compressor..

Customer: replied 1 year ago.

I have 14 volt at conector

Expert:  -Brad- replied 1 year ago.

To the compressor? Do you also have a ground?

Customer: replied 1 year ago.

Yes to the compressor, yes there is ground you think I have a defective compressor is a remanufactured not new

Expert:  -Brad- replied 1 year ago.

If you have 12v and ground and the clutch will not engage then the compressor clutch is bad..

Customer: replied 1 year ago.

Cause I have thr old one and just plug the conector to see what happens and engages right away

Expert:  -Brad- replied 1 year ago.

Then you verified you have a bad compressor.. This is one of the main reasons we only use OEM parts to prevent this issue..

Glad I could help and thank you for the positive rating.

Ok but why the old compressor was enraged at all times even with nofreon on system

Expert:  -Brad- replied 1 year ago.

I'm not sure why the original compressor was staying engaged.. You will need a scantool to monitor the pressure transducers and retrieve the codes from the TIPM to determine that..
