Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle from any charging source.
Ensure the vehicle is in "Park" mode.

2. Inspect and Replace Cabin Air Filter

Tools Required: Flathead screwdriver, new cabin air filter.
Locate the cabin air filter access panel beneath the glove compartment.
Remove the screws or clips holding the access panel in place using the flathead screwdriver.
Carefully pull out the old cabin air filter and inspect it for dirt and damage.
Insert the new cabin air filter, ensuring it is oriented correctly.
Reattach the access panel and secure it with screws or clips.

3. Check Blower Motor and Fuse

Tools Required: Multimeter, replacement fuse (if needed).
Locate the fuse panel in the front trunk area.
Identify the AC blower motor fuse using the fuse diagram.
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.
If the fuse is intact, proceed to check the blower motor.

4. Test Blower Motor Operation

Tools Required: Jumper wires, multimeter (if further testing is needed).
Disconnect the wiring harness from the blower motor.
Use jumper wires to apply direct battery voltage to the blower motor terminals.
If the blower motor does not operate, it may need replacement. If it runs, check for voltage at the connector when the system is activated.

5. Reassemble and Test the System

Reconnect any disconnected components and ensure all panels are secured.
Reconnect the battery or charging source if it was disconnected.
Start the vehicle and activate the AC system to test for airflow from the vents.
