WATER DRAINAGE AND WIND NOISE DIAGNOSIS
The sliding glass panel is designed to seal water
entry with a snug fit between the roof and the seal.
The fit can be checked by inserting a piece of paper
between the roof and the seal. The piece of paper
should have some resistance when pulled out when
the glass panel is in the closed position. The sunroof
housing will drain off a minimum amount of water.
Excessive wind noise could result if the gap clear-
ances are exceeded. The sunroof glass panel may
need to be adjusted. Refer to Section 23 - BODY/

STEP
1 If glass is not flush to panel when closed.
1a) adjust glass per service manual and verify function.
1b) check seal for damages (cuts, gaps, etc.).
2 If drain tubes (four tubes) are not draining properly,
2a) check for kinks, blockage or obstructions,
2b) verify that tubes are attached to sunroof frame.
3 If drain tubes are draining properly remove headliner and
check for leaks at drain spouts.
1 If controller is not getting power and wire harness does not
have continuity from terminal to terminal, replace wire
harness.
2 If controller is not getting power and the wire harness has
continuity from terminal to terminal check for blown fuses or
other wiring problems exterior to sunroof.

when the switch is activated (open: pin B, vent: pin D, close:
pin F). If no go to step 4; if yes go to step 5.
4 Unplug switch from controller harness, and use a multimeter

switch is pressed. If no replace switch; if yes replace
controller.
5 If motor is not getting power and motor harness is not
continuous replace harness.
If motor is not getting power and motor harness is
continuous replace controller.
If motor is getting power, replace motor.
drainage system is not plugged or disconnected. Use
a pint container to pour water into the sunroof hous-
ing drain trough. If water flow is restricted, use com-
pressed air to blow out any material plugging the
drain system. Retest system again.

(1) Remove A-pillar trim, sun visors, and map
lamps/mini console.
