A malfunctioning blower motor resistor will cause the blower motor not to work. When the resistor is bad the blower motors will not turn on.
Bad resistor at the blower motor? Bad blower motor switch?
blower motor won't work
Check to see if you have 12 volts at the blower motor. If yes then the blower motor is bad. If no, then the resistor, relay, or fuse is bad.
either the control head is bad or there is a blower motor resistor that is bad.
Blown fuse? Bad blower motor? Bad blower motor resistor? Bad blower motor switch?
Blower motor bad. Blower resistor bad. Switch bad. Fuse blown.
Could be, Blown fuse, Bad blower motor, Bad blower motor speed resistor, Bad blower switch,
A bad blower resistor will not make a vibrating noise by itself. Carefully remove the blower resistor (under the dash at the passenger side right foot area.) check to see that it is not hitting the fan. PS a bad blower resistor usually means that the blower will only operate at high speed. Usually a small fusible link on the resistor ceramic opens. Can be replaced with a small link of unmelted solder.
Blower motor fuse is blown. Blower motor resistor burned out. Blower motor switch bad. Blower motor bad.
Blown fuse. Burned out blower speed resistor. Faulty blower switch. Bad blower motor.
