The following questions I want to ask and really thanks in advanced to all of you : ))..

At the same order for each picture:

1. How this switch suppose to function? In my on both cases up or down the AC compressor works. Only in the middle it doesn't work. Is that how it suppose to work?

2. What is the purpose of the similar switches? And how the down buttons work?

3. What is the purpose of it? It works but it's in german that I don't understand.

4. When I turn the car key switch before I start the engine it goes to number 3 directly. I owned Mercedes W126 cars before and I know that it should remain on 0 until I switch on the engine then it indecates the oil pressure. It's electrical problem. How can I solve it?

5. The 'E' and 'S' switch, how it function?

I know that I'm asking too much but I hope that this information to be helpful to everyone : ))..
