It’s a bad climate, so don’t come any further.

Hello together, I tried the search, but found nothing suitable. I bought my wife yesterday a lupo 1,4l bj 2001 with manual climate. Unfortunately the compressor does not start. Safety box on battery is already cleaned and it also gets voltage through! Fans also does not work. Vcds says climate requirement is there. Normally I have always discovered the pressure switch. At lupo unfortunately not. I wanted to have bridges now to see if compressor starts. Where does it sit exactly? I only found a 3 popligen. Mhh. If it is that, which bridges should be? Seat in the mudguard behind the wheelhouse shell on the right. Before I have coolant filled up, I wanted to see if everything works and only too little coolant is on it. Still what: if there is no pressure there, and the clutch does not pull, then the fan would have to turn on anyway? I hope you can help me.
