So I replaced my ac compressor since I thought my old one was bad. I did the steps of checking the relays and fuses everything is fine. The system has freon when I replaced the new compressor installed freon and gave it a try but no luck get the same thing. The ac button is pressed replays and fuses are good air flows through the vents so the motor blower is good. Compressor clutch doesnt engage nor do the fans turn on when I have the ac option in on.
What am I missing here please need some expert help!!!
Which other steps can I do or check or the ac diagram
Please and thank you.
