sunroof controller, refer to Section 8W - WIRING
DIAGRAMS, for circuit information. If battery volt-
age of more than 10 volts is detected at the control-
ler, proceed with the following tests (the controller
will not operate at less than 10 volts).
Before beginning diagnosis for wind noise or water
leaks, verify that the problem was not caused by
releasing the control switch before the sunroof was
fully closed. The sunroof module has a water-man-
agement system. If however, the sunroof glass is in a
partial closed position, high pressure water may be
forced beyond the water management system bound-
aries and onto the headlining.

shade quides to tracks per manual and test the sunroof.
NOTE: Rear flange of sunshade should should be rearward
of water trough.
4 If motor is not running freely when removed from sunroof
module refer to electrical failure section.
5 If cables do not move freely with motor removed then check
for broken or disengaged trough guide.
1 If sunroof is open when condition occurs, inspect deflector
for broken hinges or other damaged components. If
damaged, replace with service deflector kit #05016634AC.
