Heater fan problem, HELP IT'S COLD OUT!!!

[Popeye]

On indoor fuse panel check fuse #12 and check the brown wire on back of fan switch for voltage. While you are at it disconnect it and check the terminals as well.

With vehicle on and those wires having voltage turn the blower on different settings. If you have no volts on tan, yellow, lt. blue or orange your switch is toast.

The relay turned out to be fine. Now to the switch.
