I need help in working out why my air con has recently begun operating only moderately cold. It's not French, or even European but it's what's known in V8 Supercars circles as the 'Blue' cars.
I've checked the fuses (OK), electrical connectors at the TX valve & done a 'spit' test on the High/Low gassing points where the Shrader valves are. No leaks there either. The earth point from the compressor to the block is greasy from a leaking & recently replaced headgasket which I haven't yet cleaned up and checked. Not sure if that would have an effect on it's mediocre performance though.
I don't want to waste $$$ getting it re-gassed until the problem can be identified & rectified.
Any suggestions or advice as to where to check next welcomed.
