@tiny1117 you of course checked the fuses (should be a 20 Amp fuse in #6). If the fuse is okay then you need to check the resistors pack. If unsure if it is the motor connect a 12V source right on the orange wire on your heater motor. If it spins up you know your motor is okay. That would mean it is either the blower switch or the blower resistor
