Hi,

My MK2 2006 Focus, aircon not engage, but cooling fan is working when push ac button.

i checked fuses under glove box and bonnet , all off them were fine,

i checked gas pressure is ok.

i checked pressure sensors, low and high pressure were fine.

when i push ac button, lamp will on, and cooling fan is starting to turn under bonnet, but ac compressor not turninig !!! and there is no electric is comming ac compressor cable plug !!!

IS THERE ANY CONNECTION PLUG ON THE CABLE WHICH IS BETWEEN AC COMPRESSOR AND PCM ECU ???

The PCM drives the ac relay coil. This then goes via C90 (the big connector in the Engine Fuse Box or FJB) to the solenoid.

The pressure sensors / switches are connected to the PCM.

The wiring diagram is on this site (Mk2 & Mk2a are very similar except for PJB fuse numbers!):
