Cadillac Repair: 1996 caddy sedan deville, defrosters, ac compressor


Question
my a/c was working just fine and then it started blowing hot air out it gets cold under the hood i was told it had something to do with the electical part of my vents any advise?

Answer
Is the accumulator (receiver/drier) COLD to the touch ?.

Is the AC compressor cycling as it should ?.

Does the blower motor work  to blow air thru the interior vents   ?.

If there IS air, Does it always come out of the defrosters ?.
