  4. AC Not Cooling Properly
  5. HVAC Control Module Malfunction
Problem 1: Inconsistent Temperature Control
Tools Required
  • OBD-II scanner
  • Multimeter
  • Screwdrivers
  • Flashlight
Repair Instructions
  1. If DTCs are present, address the corresponding fault codes.
  2. Remove the dashboard trim to access the blend door actuator.
  3. Test the actuator with a multimeter to ensure it operates correctly.
