The sliding window panel controls water entry at the seal.
A properly adjusted window panel ensures a snug fit between the seal and the
roof.
| • | Inspect the gap by inserting a piece of paper between the roof
and the felt seal. |
| | Maintain a minimal gap for the following reasons: |
| • | In order to reduce the amount of water that the sunroof drain
system must eliminate |
| • | In order to reduce objectionable windnoise |
| • | Complete all of the window panel to roof adjustments by changing
the height and centering of the window. |
| • | A drain trough encircles the sliding window panel and leads to
the drain hoses located at each corner of the housing. |
| | A drain channel spans the rear of the sunroof module and directs water
into the trough. |
| • | Access the hoses by removing the pressure relief valves. Refer
to Pressure Relief Valve in Body Rear End. |
| • | Route the front drain hoses down the windshield pillars and out
the center of each pillar near the upper door hinge. |
| • | Route the 2 rear drain hoses through the door lock pillars and
out of the rocker panel. |
| | This drain system provides adequate drainage for the sunroof module. |
| • | Complete the following steps if the headlining is wet or other
waterleaks occur: |
| 1. | Verify that the drainage system is not plugged. |
Clean the drainage system if the system is plugged:
| 1.1. | Use a pint size container in order to pour water into the module
housing drain trough. |
| 1.2. | Use compressed air in order to blow out any material that is plugging
the drain system. |
| 1.3. | Test the system again. |
| 2. | Inspect the drainage system for disconnected drain hoses. |
| 3. | Complete the following steps in order to obtain partial access
to drain hoses and check for disconnects: |
| 3.1. | Remove the lace from the retainer around the sunroof opening. |
| 3.2. | Withdraw the tucked headliner. |
