Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box and identify the blower motor fuse (refer to the owner's manual for specific location).
Remove the fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage rating.

3. Check and Replace Relay

Locate the blower motor relay in the fuse box.
Remove the relay and test it for continuity.
If the relay is faulty, replace it with a new relay.

4. Test and Replace Blower Motor

Reconnect the battery and test the voltage at the blower motor connector with the ignition on and climate control activated.
If voltage is present, but the motor does not operate, remove the blower motor from its housing.
Inspect for any obstructions, debris, or damage to the motor.
If the motor is faulty, replace it with a new blower motor.

5. Reassemble Components

Reinstall the blower motor into its housing.
Reconnect any wiring and the relay.
Reinstall the fuse if it was removed.
