Sunroof / Moonroof: Service and Repair: General Procedures

WATER DRAINAGE SYSTEM CHECK AND WATER LEAK CORRECTIONS

NOTE: One drain hose is attached at each corner of the roof panel. The two front drain hoses are routed down the windshield pillars and into the cowl sides exiting at the rocker panel drain holes. The two rear drain hoses are routed down the rear pillars, along the inside rear quarter panel and through the rear of the vehicle.

1. Pour water into the drain trough and inspect the front and rear of the vehicle to make sure the water drains from the rocker panels and rear quarter panels.
2. If the water flow is restricted, remove any material in the drain hose system. Test by pouring water slowly into the system.
3. Verify the roof opening panel seal is not damaged. If the seal is damaged, a new roof opening panel glass must be installed. Reinitialize the roof opening panel.
4. Check the roof opening panel alignment. Reinitialize the roof opening panel.
