1. Blower motor fuse: The blower motor fuse is located in the fuse box under the hood of your Impala. If the fuse is blown, it will need to be replaced.
2. Blower motor relay: The blower motor relay is located in the same fuse box as the fuse. If the relay is faulty, it will need to be replaced.
3. Blower motor resistor: The blower motor resistor is located behind the glove box. If the resistor is faulty, it will need to be replaced.
4. Blower motor: If the fuse, relay, and resistor are all in good working order, then the blower motor itself may be faulty. The blower motor is located under the dashboard on the passenger side of the vehicle. To replace the blower motor, you will need to remove the glove box and the passenger-side footwell panel.
Here are some additional tips for troubleshooting a blower motor issue:
* Check the condition of the blower motor connector. Make sure that the connector is clean and free of corrosion.
* Use a multimeter to test the voltage at the blower motor connector. The blower motor should receive 12 volts of power when it is turned on.
* If you are not receiving 12 volts of power at the blower motor connector, then you will need to trace the wiring back to the fuse box or relay.
If you are unable to troubleshoot the blower motor issue yourself, you will need to take your Impala to a qualified mechanic for diagnosis and repair.
