If the compressor is not cycling on and off it is probably out of 134a and there is a leak somewhere in the system.

Go to a shop that specializes in AC, they can flush the system, draw vacuum and put a leak dye in to isolate the problem.

The diverter valve may not be working or the cable that moves it is loose.
