Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.
2. Retrieve and Clear Codes
  • Use the OBD-II scanner to retrieve HVAC error codes.
  • Write down the codes for reference and then clear them using the scanner.
  • Reconnect the battery after clearing the codes.
3. Inspect and Replace Components
  • Cabin Air Filter

    • Remove the filter cover (usually located behind the glove box).
    • Take out the old cabin air filter and inspect for dirt or blockages.
    • Install a new cabin air filter, ensuring it is oriented correctly.
  • HVAC Blower Motor

    • Locate the blower motor (typically found under the dashboard on the passenger side).
    • Disconnect the wiring harness and remove the mounting screws.
    • Replace the blower motor if it is found to be faulty.
4. Check Refrigerant Levels
  • Connect a refrigerant gauge to the low-pressure port of the A/C system.
  • Start the vehicle and turn the A/C to maximum cool.
  • Check the refrigerant levels; if low, recharge the system with the appropriate refrigerant type.
5. Recheck and Test
  • Reconnect the battery.
  • Start the vehicle and operate the HVAC system.
  • Monitor for any reoccurrence of codes or symptoms during testing.
