Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety during electrical work.

2. Inspect and Replace the Blower Motor Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Refer to the fuse diagram to identify the blower motor fuse.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; replace it if blown.
Reinstall the fuse and reconnect the battery.

3. Check and Replace the Cabin Air Filter

Access the cabin air filter, usually behind the glove compartment.
Remove the glove compartment to reach the filter housing.
Pull out the old cabin air filter and check for dirt or blockages.
Install a new cabin air filter, ensuring it is oriented correctly.
Reassemble the glove compartment.

4. Test the Blower Motor

Reconnect the vehicle battery.
Turn on the ignition and activate the HVAC system.
Listen for operation of the blower motor; if it does not function, proceed to replace the blower motor.

5. Replace the Blower Motor (if needed)

Disconnect the electrical connector from the blower motor.
Remove any screws or bolts securing the blower motor to the housing.
Carefully pull out the blower motor from its position.
Install the new blower motor in reverse order of removal and secure with screws/bolts.
