I think I need to test the switch on the blower speed wheel. Does anyone know how to get access to it? Should I hear a click when the speed wheel is turned from zero to on? Thanks.


If your defrost won't come on, even with the fan switch at the OFF position, the the fan switch is not the problem. I'd suggest you start with the fusebox or relays for the system, as it sounds like you have no power to the controls.
