The clutch wont engage on compressor unless I squeeze the relay magnet
2002 nissan xterra, new compressor, new thermal control amplifier. The compressor works but the clutch wont engage unless hard wired to battery or i squeeze the magnet in the relay. I tryed switching the horn relay to see if it was out and it didnt work. Any help please i have a 10 month old baby to drive around in this texas heat!
