Opel Corsa C compressor C

Hello ...... I have a problem with the air conditioning of my Opel Corsa C ...... The compressor does not work, loading is fine ..... I think what does not work is the electroman .... Someone with a similar problem who knows solution without having to go through the workshop .....? Thank you .......... a greeting !!!!!!!!!!

To know if it is the Electro Iman: When putting the air conditioning to the engine a new load is added when turning, the air compressor. When everything goes well, when putting it it shows how the revolutiones change or if you pay attention while driving, the car stops a little. If you do not notice any of this, the Electro Ima is not hitting. I have not disarmed it, but I imagine that it will be an electrical coil that can be measured with an ohometer. If it has a small resistance between the connectors that feed it, it should be fine. Greetings.
