- Fit The New Servo In Place, Secure Fasteners, Reconnect The Electrical Connector And Reassemble Trim.
- Test HVAC Functions With Engine Running To Confirm Correct Flap Movement And Temperature Control Before Final Reassembly.
Installation Recommendations
- Always Disconnect The Battery Before Removing Or Installing The Actuator To Avoid Short Circuits.
- Inspect Wiring Harness And Connector For Corrosion Or Damage And Repair If Necessary.
- Do Not Force Flaps By Hand; Verify There Are No Obstructions In The Heater Box That Could Damage The New Servo.
