AC system, no cooled air in CAB, newly charged system

2006 Volvo excavator EC140Blc.

Things done: step 1
New control panel Fan controls work, blower motor works but no cold air. Ran dye and found blown low pressure hose.
Installed new compressor, dryer, new low pressure hose to condenser. While apart ran some lacquer thinner through condenser and blew out with air.
Hooked gauges up and pulled vacuum, let sit for one hour, no drop in pressure. Opened low pressure knob and pulled vacuum for an hour.
Purged yellow line, then reopened LP line and added correct amount of 134A. Note: cans took a while to go in, high pressure climbed to 415 PSI. Low pressure about 80 PSI. Compressor cycling on off about every thirty seconds. No cold air in cab. Fan blowing fine.

Take 2:
(I figured maybe there was a problem with my expansion valve)
Took R134A out. Pulled cab apart and replaced expansion valve. Pulled vacuum and let it sit for forty five minutes, no drop. Opened both sides of valves and pulled vacuum for an hour. Let sit over night, no loss of vacuum. Pulled vacuum for three hours or so. Then tried to add coolant. Added about an ounce of oil to line then started adding 134. By the time I added half the amount, high pressure started to clime, eventually hit over 400 PSI. Low pressure about 40 PSI with compressor running. Compressor no longer cycling on and off, but running steady. Still no cold inside. Pipes going in and out of condenser are hot. On compressor, one line hot and one cold. Still no cool in cab.
What is going on? At this point I cleared the system again, and then figured I would pull a vacuum for a long time (over night) and see if maybe that helps. But at a bit of a loss as to what is going on.
