Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the 12V battery to prevent electrical hazards.

2. Inspect Cabin Air Filter

Sub-steps:
1. Open the front trunk and locate the cabin air filter compartment.
2. Remove the cover by unscrewing any screws or unclipping it.
3. Take out the old cabin air filter and inspect it for dirt or blockages.
4. Replace it with a new cabin air filter if necessary.
Tools Required: Screwdriver (if screws are present)

3. Access and Inspect HVAC Control Module

Sub-steps:
1. Remove any necessary interior panels to access the HVAC control module.
2. Disconnect the electrical connectors from the HVAC module.
3. Visually inspect for corrosion, damaged pins, or loose connections.
4. Reconnect the module and replace any damaged wiring or connectors.
Tools Required: Socket set, trim removal tools

4. Test Blower Motor

Sub-steps:
1. Locate the blower motor, typically found under the dashboard on the passenger side.
2. Disconnect the electrical connector from the blower motor.
3. Use a multimeter to test for voltage at the connector while the climate control system is activated.
4. If no voltage is present, trace back to the control module; if voltage is present, replace the blower motor.
Tools Required: Multimeter, socket set
