Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Replace Fuses

Tool Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically found under the dashboard on the driver's side or in the engine compartment.
Identify the fuses related to the HVAC system (refer to the owner’s manual for specific fuse locations).
Remove the fuses and visually inspect them for continuity. Replace any blown fuses with new ones of the same amperage.

3. Check and Replace Cabin Air Filter

Tool Required: Screwdriver (if required for access)
Open the glove compartment and remove any screws or clips holding it in place.
Locate the cabin air filter housing and remove the old filter.
Inspect the housing for debris, clean if necessary, and install a new cabin air filter following the airflow direction indicated on the filter.

4. Repair or Replace Blower Motor

Tools Required: Socket set, multimeter
Access the blower motor, usually located behind the glove compartment or under the dashboard.
Disconnect the blower motor electrical connector and test the motor with a multimeter for proper voltage.
If the motor does not operate, remove it by unscrewing the mounting bolts and disconnecting the wiring harness. Install the new blower motor, ensuring it is properly secured.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and turn on the climate control system to check for functionality.
Adjust the settings to confirm all functions are operational.
