Blower / fan speed control switch seems to be malfunctioning. On another Suburban I owned the blower fan resistor went out but the fan would run on highest setting. I get no fan at all currently. I had fan off and on for a bit. Now, nothing.
I’m wondering if it is switch itself, a loose or broken wiring connection, or perhaps the blower motor itself. Where should I start with my diagnostic journey?
