i just replaced the thermostat in 2004 Chevy truck heater works fine now
How do you replace a defrost blower motor in a 2003 Toyota Corolla
No, the rear defrost is just an electric grid on the rear window. No air movement involved.
The year, make and model info would help. Also need to know if the blower motor is working, just not getting any heat, or not changing function between defrost, dash or floor vents.
Check to see if you are getting power to the blower motor - if so motor is defective if not problem in circuitry to blower motor
Defective blower motor resistor module. this is true except if the control module is malfunctioning at which point the defrost goes to emergency mode in which the defrost will stay on permanently. My module will not power up and I need help with wiring schematics to find a bad ground or power wire
you need a new blower motor resistor with auto temp control
Blown fuse, bad heater blower motor control switch, bad blower motor, or a bad blower motor resistor pack.
blower motor resistor is burned out
my infinity g-20 blower not working
Chack the speed control switch and the resistor that controls the speed of the motor
You will need to replace the blower motor control unit located inside the blower motor housing, this part is not the same as the part on standard explorers, it is not the same blower motor resistor.
Control switch on the dash needs to b replaced perhaps?
