A/C compressor runs on heat and a/c

On my '87 260e, the A/C has plenty of freon and the compressor works, but the air will not get cold. Or hot. No matter what temperature I set the "temperature wheel" to, the A/C compressor will stay on. The air blowing out of the vents is not HOT like on heat, but its not being cooled either. So I switched out the pushbutton unit, figuring it was bad, and it's still doing the same thing.

Any ideas? Bad Klima relay perhaps?
