The a/c heater blower motor resister is located in the vehicle on the passengers side inside the housing next to the blower motor...............Remove the blower motor resistor wire harness connector.Remove the blower motor resistor screws.Remove the blower motor resistor.
The blower motor speed resistor is burned out. You can replace only the resistor but the resistor probably burned out because the blower motor is going bad. If you want to fix it for good, replace both the blower motor and blower motor speed resistor.
Check to see if you are getting power to blower motor - if so replace blower motor If not check fuse, switch, resistor pack.
Probably a bad blower motor resistor
To change the blower motor resistor on a 2005 Malibu, first disconnect the negative battery cable to ensure safety. Locate the blower motor resistor, which is typically found underneath the passenger side dashboard, near the blower motor itself. Remove any necessary covers or panels, disconnect the wiring harness, and unscrew the resistor from its mounting. Install the new resistor by reversing the process, then reconnect the battery and test the blower operation.
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.
To replace a blower motor on the resistor first you take off the nozzle and then you go into the motor through the nozzle and unlock it then repeat and oil and done.
Blown fuse? Bad blower motor? see if you are getting power to it Bad blower motor resistor? Bad switch?
# Locate the blower resistor under the right-side of the instrument panel # Disconnect the electrical connector from the blower motor resistor # Remove the blower motor resistor mounting screws and remove the resistor from the housing # Installation is the reverse of removal
replace the blower motor switch
The blower motor resistor is defective. They go bad when the blower motor pulls to much amperage.
you need a new blower motor resistor with auto temp control
