BATTERY SYSTEM DIAGNOSIS
CONDITION POSSIBLE CAUSES CORRECTION
THE BATTERY SEEMS
WEAK OR DEAD WHEN
ATTEMPTING TO START
THE ENGINE.1. The electrical system
ignition-off draw is excessive.1. (Refer to 8 - ELECTRICAL/BATTERY
SYSTEM/BATTERY - STANDARD PROCEDURE
- IGNITION-OFF DRAW TEST) for the proper test
procedures. Repair the excessive ignition-off
draw, as required.
2. The charging system is
inoperative.2. Determine if the charging system is performing
to specifications. (Refer to 8 - ELECTRICAL/
CHARGING - DIAGNOSIS AND TESTING) for
additional charging system diagnosis and testing
procedures. Repair the inoperative charging
system, as required.
3. The battery is discharged. 3. Determine the battery state-of-charge using the
Micro 420 battery tester. Refer to the Standard
Procedures in this section for additional test
procedures. Charge the inoperative battery, as
required.
4. The battery terminal
connections are loose or
corroded.4. (Refer to 8 - ELECTRICAL/BATTERY
SYSTEM/CABLES - DIAGNOSIS AND TESTING)
for the proper battery cable diagnosis and testing
procedures. Clean and tighten the battery
terminal connections, as required.
5. The battery has an
incorrect size or rating for
this vehicle.5. (Refer to 8 - ELECTRICAL/BATTERY SYSTEM
- SPECIFICATIONS) for the proper size and
rating. Replace an incorrect battery, as required.
6. The battery is inoperative. 6. Test the battery using the Micro 420 battery
tester. Refer to the Standard Procedures in this
section for additional test procedures. Replace
the inoperative battery, as required.
7. The starting system is
inoperative.7. Determine if the starting system is performing
to specifications. (Refer to 8 - ELECTRICAL/
STARTING - DIAGNOSIS AND TESTING) for the
proper starting system diagnosis and testing
procedures. Repair the inoperative starting
system, as required.
8. The battery is physically
damaged.8. Inspect the battery for loose terminal posts or a
cracked and leaking case. Replace the damaged
battery, as required.

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. Excessive
wind noise could result if the gap clearances are
exceeded. The sunroof glass panel may need to be
adjusted. Refer to Sunroof Glass Panel Adjustment
for proper procedures.
Adequate drainage is provided by a drain trough in
the sunroof housing which encircles the sliding glass
panel and leads to drain hoses. If a wet headliner or
other water leak complaints are encountered, before
performing any adjustments, first ensure that the
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 in any of
the four drain holes, use compressed air to blow out
any material plugging the drain system. Retest sys-
tem again.
To further check for a disconnected drain hose:
(1) Remove A-pillar trim, sun visors, and map
lamps/mini console.
(2) Remove sunroof opening trim lace. Refer to
Sunroof Opening Trim Lace.
NOTE: Care must be taken not to fold or kink the
headliner upon removal.
(3) Lower headliner as necessary to gain access to
sunroof housing drain tubes. Refer to Headlining
Removal and Installation for proper procedures.
(4) Repair as necessary.
DRAIN TUBE
REMOVAL
FRONT HOSES
NOTE: Front A-pillars are filled with sound deaden-
ing foam and the front drain tubes are sealed into
the pillars.
(1) Move glass panel to the fully closed position.
(2) Disconnect negative battery cable.
(3) Remove headliner (Refer to 23 - BODY/INTE-
RIOR/HEADLINER - REMOVAL).
(4) Disconnect the drain hose from the sunroof
housing (Fig. 1).
(5) Drain any liquid from hose connection, repair
as necessary.
REAR HOUSING HOSE
(1) Move glass panel to the fully closed position.
(2) Disconnect negative battery cable.
(3) Remove headliner (Refer to 23 - BODY/INTE-
RIOR/HEADLINER - REMOVAL).
(4) Remove third seat or seats from vehicle.
(5) Remove second seat belt lower anchor.
(6) Remove third seat lower anchor.
(7) Remove quarter trim bolster.
(8) Remove trim panel screws.
(9) Remove quarter trim panel
(10) Disconnect the drain hose from the sunroof
housing. (Fig. 1).
(11) Drain any liquid from hose connection, if nec-
essary, and remove tube.
INSTALLATION
FRONT HOSES
(1) Connect the new drain hose to the sunroof
housing and test drainage (Fig. 1).
(2) Install headliner (Refer to 23 - BODY/INTERI-
OR/HEADLINER - INSTALLATION).
(3) Install sunroof opening trim lace.
(4) Connect the control switch wire connector and
install control switch.
