Hello,

I would start by checking the system fuses and relays. Here are some guides and a wiring diagram (below) of the system so you can do some testing to fix the problem.

Check the pink wiring going to the compressor to see if it has power.

This will determine if the compressor is bad or not.

Please run some tests and get back to us so we can continue helping you.

Cheers, Ken
