a/c problems

Bought another truck. 2001 kenworth w900l. A/c was not working. Discovered a hole in suction line and compressor locked up. Replaced all hoses except 3, both expansion valves, clutch, compressor, and dryer. Well no noticeable leaks. Problem is air got cool but not cold. Also when adding refrigerant it would only take a little, stop, take a little more. And the suction pressure was around 80psi(to high), and the head pressure would only build to 100 psi max(to low). I am no ac man, but know those readings are not good, also do not know what would cause this. Any ideas or suggestions would be greatly appreciated.

 

we are thinking compressor to. Yes we did pull a vacuum. No blockage, blew out condensor .

 

Compressor solved the problem but now it won't hold a vacuum and we can't find a leak. Even with the uv die. Gonna check the evaporator tomorrow.

 

Found a loose line. New oring, tightened up. Good to go.
