I drove a 1987 190E for several years before I was involved in a wreck (head on collision, left without a scratch). In any case, the electrical system just seemed to go insane for periods, then start behaving itself again. My relationship to the electrical components in that vehicle was a lot more like that between two humans than that between man and machine.
It was like Herby, I swear. One night I drove it home, no problems, shut it off. Then, at 7AM I hear the alarm. The car had definitely gone untouched all evening. When I went outside, the lights were on, the radio was blasting, and the car was half on. I kid you not, I was the sole holder of the keys. The car actually started itself in the middle of the evening with no human operation!
So, in short, I would say that your A/C sounds like it needs a new fuse. Very inexpensive, and they help the perormance of the heating/cooling system immensely.
