I'm not sure I understand what you just said. If you said that the rear is not blowing cold, check your heater control valve. Mine was stuck open, allowing hot water to the rear heater core and overcoming the evaporator.

It could be your evaporator, I'll agree. The heater core and evaporator are in the passenger side dash board above the foot well. My last experience with one of these was a 1981 model, so I may be wrong aobut yours. The 81 had access from the interior of the van, I believe.

It sounds more like a blend door, or heater core shut off. There is also a possibility of a bad vaccum control. The lever for the blend door may be broken inside the box. I had the reverse problem in a 1982 E350, no heat... The door was just jammed from when I put the new heater core in. Dad reached in and pulled the door shut, and voila! Problem solved... Instant heat, and that thing would roast you out.

I finally found crud keeping the door from closing all the way in either direction.

If the system is low on freon, it may do this too.
I get this on our E450's eldorado buses. The rear will be cold and the front will be air temp.. On these they use one compresor with the condeser on the side, with one added benifit. We have the sight glass to check for bubbles. I remember have the sight glass on some 84 e350's.
