temp control advise

My 95 S420 temp control unit is on the fritz. The lights randomly turn on and off. Move from C to F, and sometimes all lights go on. The end result often defaults to defrost mode and I'm unable to turn it off. I have replaced the regulator underneath the cabin filter, but did not fix. Any suggestions?
Thank you for your time.
