Ok, two points:
I have seen bad ignition switches give some really wierd climate control results. One car I had , the fan would sometimes not work. Then I would turn the key back, just a touch and the fan would run fine. I replaced the switch and all was well with the car.
On my '83 300D, it has the R4 compressor. The connections on it are not always great. Just a pair of 1/4 in female connectors in a common plastic housing. If that is what you have, try cleaning the connectors and maybe pinching the metal part a bit to get a solid electrical connection.
