[AT] OT: sleeper air

[Cecil R Bearden]

Ron:
Does it have a solenoid valve that opens to allow freon to the sleeper 
evaporator?  If so, it might just be a bad connection or wiring 
problem.   I have not had that much problems with expansion valves...   
However, I may be having one on my big van...
If there is no temp change on your lines, then there is probably no 
freon circulating.  I would look for a valve on the lines going to the 
back or where they tee off the main line.
