Electrical Wiring Diagram- Airconditioning circuit

Hi Everyone,

The clutch on the air con compressor is not engaging. The air con switch was on and the blower fan was running. A relay behind the battery was checked and according to the electrician, there was no power going to the relay. The fuse was fine as well. The electrician felt that there was power going to the air con switch but not being transferred to the relay.

With my limited electrical knowledge, it stands to reason that the fault lies between the switch and the relay. I suspect its an open circuit.

Can anyone advise me where the problem might lie? I also noticed that the air con switch light only comes on at certain times.

A circuit diagram showing me all the components/wiring would help me.

Looking forward to hearing from the forum
