Solution

1. Preparation

Disconnect the vehicle's battery to ensure safety while accessing electrical components.
Gather tools: socket set, multimeter, and any replacement parts needed.

2. Inspect and Replace the Climate Control Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse related to the climate control system (consult the owner’s manual for the exact location).
Use a fuse puller to remove the fuse and inspect it for damage.
If blown, replace it with a new fuse of the same amperage.

3. Check and Replace Cabin Air Filter

Access the cabin air filter compartment, usually located behind the glove box.
Remove the glove box if necessary by unscrewing retaining screws and disconnecting any wiring.
Take out the old cabin air filter and check for debris or blockages.
Install a new cabin air filter, ensuring it is oriented correctly.

4. Test and Replace Blower Motor

Reconnect the battery and turn the vehicle's ignition to the ON position (not starting).
Locate the blower motor, usually found under the dashboard on the passenger side.
Use a multimeter to check for voltage at the blower motor connector while adjusting the climate control settings.
If there is no voltage, further investigate wiring or climate control module issues. Replace the blower motor if it does not operate when powered.

5. Reconnect and Test

Reconnect all components and the battery.
Turn on the climate control system to check for proper functionality.
