1995 Newmar Dutchstar A/C issues

[Fastfunco]

Hello to all of you-. Does anyone have a drawing of the dash A/C for a 95 spartan chassis !

I have replaced controls- pressure sensor- fan switch and fan resistor clustor -

Fire up the bus- air comes on compressor is running - then condenser fan comes on as it should - pumping really cold air for about 5 min-

Then 1 by 1 compressor shuts off- fan shuts off - them blower trips it's relay and I have nothing -----??????

Shut down rig- restart -. And same thing duplicates again !

I'm stumped !!!!!

Yes I added freon - it was sitting for 12 years - however I did not change dryer - purge - hook up vacume and install the correct amount of freon- I'm thinking new compressor and freon is next
