1. Open the sunroof glass panel.
2. Withdraw the headliner from around the sunroof module.
3. Remove the power sunroof switch. Refer to Power Sunroof Switch Replacement (W/O Overhead Console) or Power Sunroof Switch Replacement (With Overhead Console).
4. Lower the headliner as needed. Refer to Headliner Replacement (Impala) or Headliner Replacement (Monte Carlo) in Interior Trim.




5. Connect any disconnected hoses.
6. Verify that the rear drain hoses are properly routed in the metal roof slot and taped in place.
