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........

sounds like you found your leak.

listen, look, .........and duck.

Run Duracool instead of 134. Much better cooling and much less operating pressures.
