Hi, new problem appeared, once I put reverse, the rear A/C fuse blew. I changed fuse #S10 many times, the problem still. Disconnected the reverse light wires and the switch above the camshaft, no change.

I am not sure the reverse lights can affect the rear A/C, but you never know. here are the rear A/C wiring diagrams so you can see how the system works. Plus, there is no #s10 fuse, can you look at the diagram to see if you recognize the fuse? Let me know and I can look up the fuse in question to see if it shares another circuit. Check out the images (below). Please let us know what you find.
