Technical Background
One or a combination of the following four possible scenarios may be present. These areas of the sunroof
system will need to be inspected as possible root causes.
1. Sunroof drain hose or outlet valve:
Visually inspect all 4 sunroof drain
hoses and valves for any damage
or obstruction (Figure 2).

2. Roof opening seal:
Inspect the entire perimeter of the
roof opening seal for any
detachment or malformation
(Figure 3).

3. Glass sunroof panels:
Check all adjustment axes of the
sunroof glass panels for poor
adjustment (Figure 4).
Figure 4. Front and rear glass panel adjustment.
4. Unexplained or unduplicated water entry:
When the vehicle is exposed to water (rain, car wash, or standing water on the roof panel) either with the
vehicle stationary or driving it is possible for water to enter the sunroof frame, breach the normal water
drainage channeling, and leak into the cabin area. This is heightened if the sunroof is opened or vented
when the vehicle is wet.

This water drip may not appear
until after a driving period when the
water travels to the underside of
the headliner area during the
normal course of driving (Figures
5-7). This occurs due to a slow
migration of water along the wind
deflector hinge arms and water
entry into the stowage area for the
wind deflector. This stowage area
does not provide water drainage
away from the vehicle.

Production Solution
Production solutions have been implemented in production. The instructions that follow are service solutions that,
when performed accurately and completely, are effective in stopping water intrusion and helps to avoid
unnecessary parts replacements.
Service
1.
Sunroof drain hose or outlet valve:
Ensure that any water in the sunroof frame drainage areas flows freely. Replace any pinched or otherwise
obstructed drain hose(s) or valve(s).
2.
Roof opening seal:
If after inspecting the roof opening seal any detachment, malformation or damage is discovered, replace the
sunroof opening seal.
3.
Glass sunroof panels:
If after all dimensional measurements are made on the sunroof glass panels a problem is found make the
necessary adjustments to the sunroof glass panels.
4.
Water entry for what appears to be through the sunroof frame:
It is not necessary to replace the sunroof frame unless there is damage found (e.g. crack in the drainage
structure, hole in the drainage structure). If damage to the sunroof frame is found, clearly mark the area of
damage. Sunroof frames replaced for damage will be requested for return to AoA for analysis. If no damage
to the sunroof frame structure is found, proceed as follows.
5.
Open the front sunroof panel
completely and locate the
mounting points for the sunroof
wind deflector (Figure 8).

be free of any lubricant or
contaminants and completely dry. Figure 9. Area of sunroof frame to be cleaned.
7.
Cut two 25mm strips of AKL 450
005 05 Butyl adhesive/sealing
cord. Firmly press each strip into
the groove shown in Figure
10. Both channels shown in the
cut away must be completely filled
with the butyl cord.

8.
Next, a small modification will be
made to the sunroof glass panel
shown in Figure 11.
