I've been working on my dash AC. It has never been working(reliably) since I bought the coach 8 years ago.
I replaced the compressor, the dryer, expansion valve and
flushed out the condenser.

I put ester oil in the compressor (after draining out
whatever was in there). I evacuated the system for
30 minutes and charged it with 2 1/2 cans of Duracool.

I have 110 PSI with the engine off. When idling I
get 20 PSI on the low side and 200 PSI on the high side.

It blows cold air at first when idling. After 5 minutes
of running the belt starts slipping. I tightened the belt
and it ran again for about 5 minutes before the belt started
slipping again.

I replaced the belt with a Goodyear 15615 Gatorback.
The new belt doesn't slip. But now the clutch slips.
The compressor gets very hot when this happens.

Any ideas what could be wrong?
Do you think the compressor is clogged up?

Thanks,
Bill
