Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, screwdrivers
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Replace Blower Motor Fuse

Locate the fuse box, usually found in the engine compartment or under the dashboard.
Remove the fuse for the blower motor using the fuse puller.
Inspect the fuse and replace it if it is blown. Ensure to use the correct amperage rating.

3. Replace Blower Motor Relay (if necessary)

Locate the blower motor relay, usually found in the fuse box.
Remove the relay by pulling it straight out from the socket.
Install a new relay by pushing it firmly into the socket until it is secure.

4. Test and Replace Blower Motor

If the blower motor still does not operate, disconnect the wiring harness from the motor.
Use a multimeter to check for voltage at the blower motor connector; if voltage is present, the motor is likely faulty.
Remove the blower motor:
- Unscrew any retaining screws or bolts.
- Carefully pull the blower motor out of its housing.
Install the new blower motor by reversing the removal steps and ensuring it is seated properly.

5. Reassemble and Test
