Hope this is a fresh question, but if someone has seen this problem before have your say, hassle me but please point me in the right direction.
Took V8 Limited to get re-gassed. EMV not working but under the impression that aircond will work without it. Prior to re-gas, could hear the compressor coming on and off when switching aircond on and off, so assumed it was functional. System is full of refrigerant gas. Compressor engages and disengages. Electrician had to bridge out aircond solenoid because switch signal from car "flickers" and doesn't stay on, thus compressor comes on and off sporatically, is this because the EMV is not working?
Also the compressor switches on but doesnot pump the refrigerant gas, is this also because of the fault in the EMV, or is it because the compressor could be cacktus?
Just wanted to know if anyone can help, before I try locate a second hand aircond compressor.

Not sure about the EMV but with the compressor, does it have refrigerant in it?
How do you think it's not moving the gas? Do the pressures not change when the compressor is running?
The output signal to trip the compressor will be dependent on a bunch of things including feedback from the compressor, pressure switches and ambient temp sensors so the fact that the signal is flickering doesn't mean anything.

Hi Luke, pump has not seized, when switched on it engages the pulley.
Hi Matt, yes there is refrigerant, the gas isn't moving the electrician that had the car today said the system was full, but shows no pressure movement when compressor is on on his gauges.
Maybe a blockage but the compressor doesnt make any noises like its struggling, maybe seals or vanes are gone in it. No idea!
So if theres no pressure would that send a signal back to the EMV which in turn returns a signal to compressor to switch off, kind of a dog chasing its own tail!
