    I have a 2013 Pete 389 glider my cab blower motor quit working. Have power to blower motor but no power at plug on fan speed switch or at plug on resistor. Checked all fuses and they are good. Relay clicks when I turn on switch. Ant help would be appreciated.

    How can you have power to the motor but not the switch? The power goes through the switch.

    I thought the same thing but that is what I have and was hopeful that someone would be able to tell how it supposed to work.

    If there is power and ground at the motor, it should turn. What are you using to measure?
    Could be a fried motor
