DIAGNOSIS AND TESTING - SUNROOF
Before beginning sunroof diagnostics verify that all
other power accessories are in proper operating con-
dition. If not, a common electrical problem may exist.
For circuit, splice and component descriptions (Refer
to 8 - ELECTRICAL/WIRING DIAGRAM INFORMA-
TION - DESCRIPTION). Check the condition of the
circuit protection (fuses, circuit breakers or fuse
links) Inspect all wiring connector pins for proper
engagement and continuity (Refer to 8 - ELECTRI-
CAL/WIRING DIAGRAM INFORMATION - DIAG-
NOSIS AND TESTING). Check for battery voltage at
the power sunroof control switches. If battery voltage
is detected at the control switches, proceed with the
following tests.
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.
