Does anyone know the button sequence to start the climate control self test that will hopefully tell me the how to run the diagnostics to locate possible issues? The front AC will not turn on at all while the rear AC works fine. So i know it is not the compressor or freon. i am not educated on electronics which limits my ability to self diagnose and fix, but looking for possible fixes before i take it to the dealer. In the user manual, there are about 6 or more potential relays or fuses. Any other ideas to troubleshoot this problem would be greatly appreciated.
