Air Conditioning Compressor Signal

Air Conditioning Compressor Signal - 09/23/14 11:23 AM

My air con compressor is not kicking in, specifically the a/c cut relay isn't receiving the signal to ground it's coil which then activates the compressor clutch.
Relays and fuses are all fine, a/c clutch activates when fed direct power, condensor fan runs, have also jumpered the a/c pressure switch. Still no luck as yet.
Apparently the ECM plays a part in a/c activation too.
Anyone got any tips/ideas?
Cheers
Dave
