The sunroof glass panel controls the entry of water at
the seal. If the sunroof glass panel is correctly adjusted, the fit between
the weatherstrip and the roof is snug.
Complete the following steps in order to test the fit:
| • | Insert a piece of paper between the roof and the weatherstrip. |
| • | Close the sunroof glass panel. |
If you notice some resistance when you pull out the paper, the fit is
correct. A minimal gap is necessary in order to ensure that the water to the
sunroof drain hoses is not excessive. Excessive gap clearance may cause
objectionable wind noise.
| • | Complete all adjustments of the sunroof glass panel to the roof
by changing the height and centering of the sunroof glass panel. Refer to
Sunroof Panel Vertical Adjustment
. |
| • | A drain trough encircles the sliding sunroof glass 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. |
| • | Ensure that the front drain hoses are routed down the windshield
pillar and out the center of the pillar between the door hinges. |
| • | Verify that the rear drain hoses are routed through the rear 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
water leaks 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 drainage system again. |
| 2. | Replace any hose that is cracked, torn, or completely plugged. |
| 3. | Inspect the drainage system for disconnected drain hoses. |
| 4. | Complete the following steps in order to obtain partial access
to drain hoses and inspect for disconnects: |
| 4.1. | Withdraw the tucked headliner. |
| 4.4. | Verify that the rear drain hoses are properly routed in the metal
roof slot and taped in place. |
| 4.5. | verify that the front drain hoses are routed properly and are
not being pinched by the roof panel. |
