Hi, A/C compressor is not activated when l turn on A/C button. A/C button has three pins and only has power. Relay and all fuses are okay.

Hello,

First make sure the system has a good charge which you can do by following this link.

Next here is a wiring diagram (BELOW) and a guide so you can do some testing. As you can see by the diagram there are many fuses that run the system.
