Hi All
The aircon all of a sudden stopped working on my 107.
I found a leak on one of the valves. There was no gas in the system at all.

Valve fixed and refilled with gas.

When the aircon button is pressed the compressor doesn’t click in. I checked the feed to the compressor and nothing there. To eliminate the compressor I manually put a voltage to the clutch and it clicks, connects and starts turning. As it’s turning the pipes get cold and the aircon is working like normal.

When the original wiring is connected back to the compressor, clutch not working.

I know the pressure sensor is working as when the aircon button is pressed the radiator/ condenser fan comes on..

What I would like to have help with, is, the wire to the aircon compressor should be live when the aircon button is pressed. Where does this wire go too. I can’t find any wiring diagrams for the compressor side.. All fuses ok. The wire goes up over the engine and into the main engine loom.

The wire must go to some kind of module, but haven’t got any diagrams for this.

I hope someone can help.

Thank you

I’ve just checked the fusebox and there is a relay (grey one) in there. Checked it and it wasn’t fully fitted.
I pushed it back in and hey presto aircon working..
I took a photo of the fusebox and put an arrow in the relay but can’t seem to attach it..

Anyway, thanks for your help and I hope this can help someone else..

Just added attachment ..

I've looked for many years for a wiring diagram of the air con on the bugs, but never managed to find one :?:
