Blower motor runs right on low m1, m2, but only runs on Low, when switch setting is on high... I have replaced switch, resistor, relay, and motor. Test shows 3 volts on low switch setting, 6 volts on M1, 8 volts on M2, and 12 volts on high at the motor. Have cleaned the ground on motor.... not sure what way to go next?
Thanks
