Rear Sunroof Housing Drain Hoses - Sedans

1. Remove the roof rear panel assemblies (rear roof applique's) from the left and right side of the vehicle. (Refer to "Panel-Roof Rear Outer-Sedan" in the "Roof, Rocker Panels and Attaching Components" section of the appropriate year Body/Repair Service Manual.)

2. Remove the quarter outer panel hole plugs on the left and right side of the vehicle. (Quarter outer panel hole plugs are located under the rear of the roof rear panel assembly.)

3. Inspect both sunroof housing rear drain hoses through the quarter outer panel holes to determine if they are kinked. (The sunroof housing rear drain hose(s) may have been kinked by the installation of the sunroof housing rear drain hose grommet(s), which are located below body plug.)





^ If either of the sunroof housing rear drain hoses are kinked, remove the kinked sunroof housing rear drain hose(s) and replace with a new sunroof housing rear drain hose(s) (P/N 21052849) and sunroof housing drain hose clamp(s) (P/N 01626260). (Refer to "Rear Drain Hose Grommet-Sedan" in the "Vehicle Interior Systems" section of the appropriate year Body/Repair Service Manual.)

^ If neither of the sunroof housing rear drain hoses are kinked, remove each sunroof housing rear drain hose from the sunroof housing and proceed to the next step.

4. Using a standard air gun, limited to 207 kPa (30 psi), blow into the sunroof housing rear drain hole(s) with the obstruction and attempt to clear the obstruction.

^ If air flows freely through both sunroof housing rear drain hoses, there is no obstruction. Reattach sunroof housing rear drain hoses and refer to "Sunroof Module Sealer" in this bulletin.

^ If at first air does not flow freely through either of the sunroof housing rear drain hoses, then starts to flow freely, obstruction has been removed. Reattach sunroof housing rear drain hoses.

^ If air does not flow freely through either of the sunroof housing rear drain hoses and obstruction cannot be removed, replace sunroof housing rear drain hose(s) with new sunroof housing rear drain hose(s) (P/N 21052849). (Refer to "Rear Drain Hose Grommet-Sedan" in the "Vehicle Interior Systems" section of the appropriate year Body/Repair Service Manual.)
