Sunroof Drain Inspection and Cleaning
Sunroof Drain Inspection and Cleaning
The drain trough in the sunroof module provides adequate water drainage. The drain trough encircles the sunroof window panel and leads to the drain
hoses. The sunroof drain hoses are located in each corner of the sunroof housing. A drain channel spans the rear of the sunroof module. The drain
channel directs water into the trough. The front drain hoses are routed down the windshield pillars and out the rocker panels. The rear sunroof drain
hoses are routed down the B, C, or D-pillars and out the bottom of the vehicle.
Caution: Wear safety glasses in order to avoid eye damage.
Important: Care must be taken when using compressed air to clear the sunroof drain hoses. Do not exceed 241 kPa (35 psi).
If a wet headliner or other water leaks occur, verify that the drainage system is not plugged or disconnected. This should be done before performing any
adjustments to the sunroof window panel. Inspect for a plugged or disconnected drainage system by opening the sunroof window panel and pouring a
small amount of water into the sunroof module drain trough. If the water flow is restricted, use a flexible wire or 241 kPa (35 psi) of compressed air to
clear out any material plugging the drain system.
Retest the system for proper water drainage.
If water drainage is still not adequate, the headliner will need to be removed to inspect for the proper routing of the sunroof drain hoses. Refer to
Headliner Replacement (Rendezvous) (See: Interior Moulding / Trim/Headliner/Service and Repair) in Interior Trim.
Allow only a minimal gap between the roof and the weatherstrip. The seal fit is essential to assure that the water and debris going to the sunroof drain
hoses is not excessive. Objectionable wind noise may result if the clearances are exceeded. Make sunroof glass panel to roof adjustments by adjusting the
height and centering the sunroof window panel. Refer to Sunroof Window Height and Opening Fit Adjustment (See: Adjustments) .
