So the '82 MB appears to have been converted to R134a, given the appearance of those retrofit nozzles.

Weather got warm today, and the A/C has not been cooling at all, so I went down and picked up one of those "all in one" recharge canisters with the built-in meter.

As directed, ran engine, max A/C, plugged into low-pressure valve, squeezed the trigger. Looked as if it was taking a charge. Then... did I hear something (?). Not sure, removed recharge hose and found that gas was leaking straight out of the low-pressure valve.

Assuming failure of this valve is what is the issue here -- is that a common problem?

Bad idea to take a road trip if there is no gas in the system? Compressor might seize from lack of lubricant?

Thanks,

Chuck
