Was the Evap Core leaking or the connections/Evap valve ?

There is a little fitting inside the aftermarket expansion valve and it was not seated correctly

Did you dump the mineral oil out of the new compressor and replace with the equivalent PAG 46?
(Assuming you're converting to R134A)

I added PAG 46 to everything yes

Aight. We good. System held vacuum. Radiator shop said the condenser is clean as a green bean. I added a touch of PAG to it and it’s ready for charging on Tuesday at @wct49’s shop.

Once the AC is cold it’s going home.

Good news.

49tire got the AC charged and there are no leaks!

Bad news.

The AC amplifier is toast. Rob seems to think this may have been the reason I cooked the compressors. It never let them cycle.

AC is super cold when you jump the compressor off though.

Anyone have a spare AC amplifier?

This truck is smooth as glass at 80

Those Amplifiers are hard to find in good condition. I believe @Engineer8000 can repair them ? Also, there's a thread where a member was able to substitute a modern digital version for the Compressor cycling function, if you're interested in that kind of fix.

Another plug for Engineer8000, I had a great experience with his services.

Dropped the AC amp in the mail to Engineer8000 today and I’m taking Woodrow home tomorrow.

First Rate! Beautiful rig. Have to keep an eye on the highways for it.

Same here. Great experience with @Engineer8000 repairing AC circuit board

@wickwest has some great vehicles

Had the exact same problem on a four seasons expansion valve on my 87 mini truck - ended up replacing it with a Denso.

Figure the condenser and the lines were full of crap and it locked the compressor up once it started cycling through. Great job on the A/C install, always good to clean everything with brake cleaner and an air compressor.
