Hi! My name is AutoDoc1. What’s your name?

I’m sorry that you’re having trouble with your vehicle but don’t worry though, we’ll be able to figure this out.

Please understand that I do not know your knowledge or capabilities so I may need to ask questions to find out basic information to help solve your specific problem.

Sometimes I have to look up some information so it may take a moment to respond. I appreciate your patience.

The system will give you an automated phone call offer to speak to one of us on the phone. It is optional. Some folks prefer to talk on the phone. If you don’t, please ignore it as I cannot control the offer from popping up.

This is a common problem on this vehicle and usually requires the replacement of the lift gate control module.

The cause of this condition may be a rear sunroof drain hose that may be kinked or crushed by the rear body side trim panel(s), which may allow water to backup or leak into the rear floor area.

Recommendation/Instructions

Complete the following inspection procedure before doing any repairs.

Water Test Inspection Procedure

Important: When pouring water onto the sunroof panel, ensure that the water is directed into the outboard track of the frame (shown by the arrow above) and NOT into the inboard track and mechanism.

1. Park the vehicle on a level surface.
2. Fully open the sunroof window.
3. Fill an appropriate container with approximately 16 ounces (473 ml) of water.
4. Pour water into the outboard channel of the sunroof frame on one side of the vehicle, and immediately inspect the area behind the rear wheel opening for water flowing out under the fascia.
5. Repeat steps 3 and 4 on the opposite side.
   • If water is NOT properly flowing out the rear drain hose, remove the quarter trim panel on the affected side and inspect the sunroof drain hose for proper routing and/or damage.
   • Any damaged/kinked drain hose must be replaced.

If the liftgate is inoperative, and/or water is found in the rear cargo floor area, inspect the pump assembly and control module for signs of water being present.
