Ford a/c pressure too high on low side

[junkyardjeff]

I tried to put a a/c system from a 95 f150 on my 88 bronco but some of the parts would not fit since i did not get the housing that mounts to the firewall so I used the compressor and receiver drier on the 88. It was converted to 134 before I got it and since some parts came off a 95 that had it I put some in and tried to get it to work,well it wants to get cold and has about 50 psi on the low side so something else is wrong. The original compressor was shot and the orfrice tube was clogged so could the evaporator and condenser be plugged too.

Did you replace the drier too? In that era there was a problem with desiccant breakdown that can plug the orifice in short order.
