Hello,

There are three fuses that run the system that we need to check for power. Here is a guide to help us get started with the air conditioner wiring diagrams so you can see how the system works along with the fuse locations below. Checks interior fuses, ECU ACC, HTR and engine compartment fuse ECU-B

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken
