SUNROOF DRAIN INSPECTION AND CLEANING
Drain Hose Routing
NOTE: If the headliner is wet DO NOT remove any interior trim. Do
the Plugged Drain
Hose test first.
A drain trough encircles the sunroof window panel and water is drained off by
the drain hoses located at each
corner of the housing. A drain channel spans across the sunroof module at the
rear of the window panel and
directs water into the trough.
- The front drain hoses are routed out of the left and right corners of
the plenum. The front hoses are
installed through a rubber grommet that seals the hose tightly in the plenum.
- The rear drain hoses are routed through the left and right rear lower
quarter panel and out of the body.
The rear hoses are installed through a rubber grommet that seals the hose
tightly in the quarter panel.
Plugged Drain Hose
In some vehicle it may be necessary to clean the sunroof drain hose by
applying air from the lower end of the
drain hose outlet instead of the upper drain hose outlet.
If a waterleak has occurred check for a plugged sunroof module drain hose at
each corner of drainage system by
doing the following:
- Open the sunroof window.
- Locate each sunroof module drain hose outlet area.
- With a visual look, ensure that all the hoses are attached to the
sunroof module drain outlet.
- Cover all of the interior before air is apply to the drain hose.
- To test for blockage, pour a small container of water into the module
housing drain trough. Check each
corner to confirm the drain hose is draining water if not go to step number
6.
WARNING: Wear safety glasses in order to avoid eye damage.
- Use compressed air, 241 kPa (35 psi) or less to blow out any drain hose
that is plugged.
- Test the system again.
- If remain plugged remove the blockage using the following steps.
- Push mechanics wire through the hose to remove the obstruction.
- Use compressed air in order to blow out any remaining material.
- If the hose remains plugged, check to see it is properly routed and does
not have a kink. Refer to Sunroof
Housing Front Drain Hose Replacement, or Sunroof Housing Rear Drain Hose
