Air con no longer working!

[jev]

Took my air con to be re-gassed. What was a working system works no longer!

There seem to be 2 High Pressure valves. One is obviously the air con system, but the other is on a pipe the other side of the engine (same side as the compressor). This is what they tried to charge 1st time around.

2nd time around they charged the right valve - 775g. Result now virtually no cooling.

3rd time around machine reports a leak and won't charge.

Any ideas? Might the attempted charge on the wrong valve have damaged the system? Or worse damaged something else?

Off to South of France tomorrow so aircon would be nice!

Thanks in advance.

Sorted! I hope.

BTW, the low pressure valve is below / hidden by the expansion tank.
