    . Check the blower motor relay in the under hood fuse/relay box.

    . Check all under hood and under dash fuses with a test light or multimeter.

    . Check if the fan motor will run on High. If it does, the problem may be with the blower motor resistor.

    . Check continuity in the blower motor switch.
