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.
