w201 2.5-16V a/c problem

[gisek]

Hello all of 16V owners.
I`am proud 2.5-16V user and I am looking for any info about a/c system. I have this type (http://img66.exs.cx/img66/8997/w201_euro_klima.gif on the right). Problem is that, it doesn`t work. I would like to check what causes problem, but i did not find a proper diagram (etc.) that shows position of a/c parts in engine compartment. Especially I `am interested in posistion of these parts:
- a/c compressor pressure switch
- refrigerant pressure switch.

Recently I had to fix a/c compressor socket because it was almost smashed. Socket is just fine know, but still a/c does not work. Maybe You can help me?

Hello Gisek,
I think I've got what your're looking for.
I've sent you a PM, look in your Box.
It' s in german, I hope this works for you, if you have problem in translating something, just ask.
If you need anything else, just ask.
And please set a short answer here, when you got it, so I can take it off again.

Regards
Ilp

Thank You for file. I really do not understand german so good so I will be pleased if You can help me with it. I would like to understand they way this klima works. It depends on few things, switches also, pressure in klima system etc. As I wrote I fixed socket of klima copressor, KLIMA Relay i think is alright also, know I` am looking for is switch that checks pressure in klima system and magneticswitch of klima compressor. Maybe You will be able explain it?:)

you have two pressure switches on the "Trocknerpatrone", it´s the thing behind the left front light. one is for the fan switch, and the other for the main pressure.

And where can I find magnetic switch for klima compressor? It should be somewhere in engine compartment, I`ve looked it in front of engine head (there are four switches there). I will look for these two switches You`ve mentioned and then I`ll think what next. These pressure swithes should have some precise resistance? I will check them with multimeter.

I`ve checked pressure switch for main pressure (switch turn on the a/c compressor), but i think there`s no voltage in it`s cables. Does anyone know what gives poweer to this switch?
