Cadillac Repair: 96 Cadillac Deville Heat Only, cadillac dealer, cadillac deville

Question
I have a 96 DeVille which only blows extremely hot air.  The AC/Heater motor was replaced by Cadillac dealer about 18 months ago.  No other repairs since then except adding a charge of freon.

Now only hot air blows from all vents.  The AC compressor runs and the lines in the engine compartment are freezing.  I believe it is the AC/Heater programmer.  Is there an easy check?

Thanks is advance for this great service.
