Car: 1987 300SDL (W126.125) w/auto climate control.

Here's one you've heard before: My AC compressor keeps kicking in on "EC" cycle. It's a new compressor (10K) and the car's third one.

If it was just that simple, I'd replace the module. However, I can get it to turn off by firmly pushing in on the EC or Off buttons. After a while, it will come back on again, along with the blower. Do I need a new module, or new buttons? Please advise.
