do not use the wheel until the size and type have been
properly identified. Wheels of different diameter,
offset, or width cannot be mixed on the same axle. Bead
seat tapers cannot be interchanged.

SUN ROOF - POWER
1998 Mitsubishi Montero
1998 ACCESSORIES & EQUIPMENT
Mitsubishi - Power Sun Roofs
Eclipse, Galant, Montero, Montero Sport, 3000GT
DESCRIPTION & OPERATION
Sun roof is actuated by an overhead console-mounted switch.
Sun roof motor, located near switch, moves sun roof panel by means of
drive cables. If necessary, sun roof can be closed manually using
manual closure wrench stored in vehicle's tool pouch.
On vehicles equipped with Electronic Timer Alarm Control
System (ETACS) ECU, sun roof can be operated up to 30 seconds after
ignition switch is turned to OFF position.
Sun roof motor incorporates a safety feature that initially
limits opening or closing of roof glass panel. Sun roof will not fully
close from fully open position without first releasing and then
depressing slide switch during operation. Sun roof initially stops
about 8" short of fully closed position.

SERVICING
LUBRICATION
NOTE: Only Lubrication procedures during reassembly of sliding
roof assembly components are available from manufacturer at
time of publication.
ADJUSTMENTS
SUN ROOF FIT
1) Fully close sun roof. Fully open sun shade. Remove side
covers from underneath sun roof. Loosen 6 sun roof glass mounting nuts
and adjust glass forward, backward or sideways, if necessary.
2) If adjustment cannot be made by loosening mounting nuts,
check if sun roof glass or motor is in fully closed position. Readjust
as necessary.
Page 1216 of 1501
SUN ROOF GLASS FIT
1) Fully close sun roof. Ensure roof glass panel is parallel
with roof opening. Sun roof glass panel parallelism should be within .
04" (1 mm), above and below roof surface. If parallelism is not as
specified, adjust glass panel by loosening sun roof glass panel
attaching screws and repositioning glass panel. Tighten screws. See
Fig. 1 .
2) If adjustment cannot be made by loosening mounting screws,
check if sun roof glass or motor is in fully closed position. Readjust
as necessary.

SUN ROOF MOTOR CLUTCH CHECK
Page 1217 of 1501
Except Eclipse & Montero Sport
1) Remove sun roof motor. See DRIVE MOTOR R & I under REMOVAL
& INSTALLATION. Using crank handle stored in tool pouch, place crank
handle into drive motor shaft.
2) Place spring scale on crank handle about 3.92" (100 mm)
from drive motor shaft. Ensure spring scale is at right angle to crank
handle. On Galant, connect battery source to sun roof motor connector
terminals No. 1 and 4 to rotate motor. See Fig. 4. On Montero, connect
battery source to sun roof motor connector terminals No. 1 and 3 to
rotate motor. See Fig. 5. On 3000GT, connect battery source to sun
roof motor connector terminals No. 1 and 2 to rotate motor. See Fig. 6
.
3) On Galant, spring scale should read 30-38 INCH lbs. (3.4-
4.3 N.m). On Montero and 3000GT, spring scale should read 35-43 INCH
lbs. (3.9-4.9 N.m). If clutch sliding force is not as specified, on
Galant and Montero, adjust motor adjusting nut to left or right. On
3000GT, replace sun roof motor.

COMPONENT TESTS
DRIVE MOTOR
Eclipse & Montero Sport
Remove drive motor. See DRIVE MOTOR R & I under REMOVAL &
INSTALLATION. Using 12-volt power supply, apply voltage to 2-terminal
connector. Reverse power supply leads to reverse motor direction.
Replace motor as necessary.
Galant
Remove drive motor. See DRIVE MOTOR R & I under REMOVAL &
INSTALLATION. Using 12-volt power supply, apply voltage to terminals
No. 1 (Blue wire) and No. 4 (Blue/White wire) of 6-terminal drive
motor connector. Reverse power supply leads to reverse motor
direction. Replace motor as necessary.
Montero
Remove drive motor. See DRIVE MOTOR R & I under REMOVAL &
INSTALLATION. Using 12-volt power supply, apply voltage to terminals
No. 1 (Green wire) and No. 3 (Green/Red wire and Black wire) of 4-
terminal drive motor connector. Reverse power supply leads to reverse
motor direction. Replace motor as necessary.
3000GT
Remove drive motor. See DRIVE MOTOR R & I under REMOVAL &
INSTALLATION. Using 12-volt power supply, apply voltage to terminals
No. 1 (Red/Blue wire) and No. 2 (Red/Yellow wire) of 8-terminal driv\
e
motor connector. Reverse power supply leads to reverse motor
direction. Replace motor as necessary.
DRIVE MOTOR LIMIT SWITCH
Eclipse & Montero Sport
1) Remove sun roof ECU. Look into viewing windows while
turning rotating wheel. See Fig. 2. Turn rotating wheel until White
marks appear. When White marks appear in viewing windows at same time,
stop turning rotating wheel.
2) Close sun roof fully. Install timed sun roof control unit.
Ensure wiring connector is properly inserted into control unit. Insert
a flat-blade screwdriver, place on tab and press to right, being
careful not to pinch wiring. See Fig. 3.
