Here is the wiring info for your radio. I have some other wiring diagrams but did not see anything related to your ac. Hope it helps and let me know if you want the other wiring diagrams. Also once you know what these wires are then you will be able to tell what wires are not related to your radio and might be able to figure out which wires are causing your other problems?
