The resistor motor may have went out if the heater blower quit working on a 2004 F-250 Truck. The cost to replace the motor is approximately $200.
replace heater relay and or heater blower motor
Blower fan resistor under glove box...by passenger's feet...!
The blower motor resistor pack is bad.
One reason a 2004 Monte Carlo heater motor blower may not work is low coolant. You can check the coolant level after the car has been turned off.
its the blower resistor.
Depends on what you mean by heater will not work. If the blower motor will not work, it can be a blown fuse, bad blower motor, bad blower motor switch, or a defective blower motor resistor pack. If you mean that the blower motor works but there is no heat, then it can be a clogged heater core, thermostat stuck open, or defective heater control valve.
There might be a bad fuse causing the heater to not work. Check the fuses if they are all ok you may have a bad blower motor. when you turn the heater on and no air is blowing then it is your blower motor.
You most likely will have a bad blower resister........
