1981 Cadillac Coupe DeVille

Does anyone know where to get rebuilt programmers? I need specifically for the 81 as it has MD. I've tried replacing it with a unit from an 85 and the heating system just goes haywire.

The A/C periodically blows to the floor. It will fix itself randomly. It's not a vacuum leak, I think the switches that switch the vacuum are getting worn out - I had this problem 5 years ago and luckily found one in a wrecker but now it's starting to show symptoms of failing yet again...
