Airco problems, help needed

Hi all, i bought a 97'er 155, it's an 1.8 TS 16V with AC, but it doesn't work.
So what's the problem, I found out that the compressor doesn't get any power. There's a brown cable adjusted to it and a black one that comes from the pump itself.
So when I turn the airco on nothing happens.
So I thought it had to do with the system needed to refill but when i got to an airco service center they told me that they couldn't do anything because the compressor didn't get in because of the power problem.
I did check all the relais and fuses and they all seem ok.
Does anyone of you have an electrical diagram of the airconditioning system?
Or any other tips??? Any help would be very great!
Thanks in advance.

Hi Maurice,

Its possibly one of many different things and its hard to say from your description. Maybe someone else with more knowledge will be able to help you, but in the meantime you should check your private mail or (sorry) put yourself in the hands of a garage

I don't thinks it's the panel because i can hear the relay clicking when i turn the aircon on.
So where is that pressure gaurd you say and how does it look like?
I've heard that does things give a lot of problems so it's worth a try because they're not that expensive.

Problem solved guys! Thanks to the help from a friend who's an electrician. The problem was the relay infront of the battery. After cleaning it the aircon worked again. So now i'm happy!!!
