DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
Before beginning sunroof diagnostics verify that all
other power accessories are in proper operating con-
dition. Refer to Sunroof Diagnostic Chart for possible
causes. If not, a common electrical problem may
exist. Refer to Group 8W, Wiring Diagrams, of this
publication for circuit, splice and component descrip-
tions. Check the condition of the circuit protection
(20 amp high current fuse (battery feed) located in
the Power Distribution Center (PDC). Check the
cover of the PDC for location of the fuse. The ten
amp fuse (ignition feed) located in cavity 14 of the
Junction Block). Inspect all wiring connector pins for
proper engagement and continuity. Check for battery
voltage at battery and ignition pins of the power sun-
roof express module wiring connector. Refer to Group
8W, Wiring Diagrams, for circuit information. The
controller will not operate at less than 10 volts.
Check the ground at the sunroof express module.
Before beginning diagnosis for wind noise or water
leaks, verify that the problem was not caused by
releasing the control switch before the was sunroof
fully closed. The sunroof module has a water-man-
agement system. During washing high-pressure
water may be forced between the glass panel seal
and the roof opening. Normally this water will drain.
However, when some type of drying blower system is
used, like those found in automatic car washes, the
water may not have a chance to drain before the
blower forces air between the seal and the roof open-
ing. This causes the water to blow over the edge of
the module and onto the headlining.
Refer to (Fig. 1) Sunroof Assembly for exploded
view of the sunroof.
