Is it my imagination, or my 85 300D AC Pressure Switch is leaking? I was using R134 which has a higher pressure and yesterday after I had tested and inspected the entire system, low and behold I installed the R134 and I couldnt believe it, plumes of freon bubbles soming out of the spade connectors on the Drier Pressure Switch.

Was this the real leak? I inspected, flushed and rebuil the entire system after it died mysteriously last September........
