2004 expedition ac problem

I have front and rear ac. It does not get cold in the front but
the back seems to be working ok. I had to replace the
compressor at the start of winter cause of a clutch
bearings lock up. Now that it's hot I charged it up and I'm
not getting cold air up front but I do in the back. Replaced
the expansion valve for the front and blew air thru the
evaporator and got alot of oil out of it but still no change. It
dont leak and the pressure seems to be fine. What are
some possible causes of this?
