How to replace ignitions switch in 1990 XJ

 

IGNITION SWITCH REMOVAL
(1) Disconnect the negative battery cable at the
battery.
(2) XJ models: Remove the lower instrument panel
trim assembly. YJ models: Remove the windshield
wiper intermittent control module and its bracket (if
equipped).
(3) Place the ignition key lock in ACCESSORY position.
(4) Remove the two headlamp dimmer switch attaching nuts. Lift the switch from steering column
while disengaging actuator rod.
Before removing dimmer switch, tape the two
remote control actuator rods (ignition switch
and dimmer) to the steering column. This will
prevent accidental disengagement from the upper part of the steering column.
(5) Remove the ignition switch-to-steering column
attaching screws.
(6) Disengage the ignition switch from the remote
actuator rod by lifting straight up. Remove switch
from steering column.
(7) Remove wiring from switch as follows:
Two electrical connectors are used to connect all
wiring to the ignition switch. One of the connectors
is installed (interlocked) over the top of the other
connector. Remove wiring from switch by disconnecting the (black) harness connector first and then the
other connector. Remove the switch from the vehicle.

IGNITION SWITCH INSTALLATION/ADJUSTMENT
(1) Place the key lock switch in the ACCESSORY
position.
(2) Place the slider bar (in the ignition switch)
(Fig. 2) into the ACCESSORY detent position.
(3) Connect the wiring to the switch as follows: Install the non-black (colored) connector first and then
the black (colored) connector to the ignition switch.
One connector will interlock the other connector.
(4) Slip the remote actuator rod into the access
hole on the switch (Fig. 2).

Install the switch to the
steering column. Be careful not to move the slider
bar (on the switch) out of the ACCESSORY detent
position. Remove the ignition switch actuator rod securing-tape from steering column.
(5) Install the two ignition switch-to-steering column screws finger tight. Do not tighten screws at
this time.
(6) Adjust ignition switch as follows:
(a) Non-tilt steering column: While holding key
lock switch in ACCESSORY position, gently slide
ignition switch up (towards steering wheel). This
will remove slack from switch. Tighten attaching
screws. Do not allow the ignition switch to move
from the ACCESSORY detent position.
(b) Tilt steering column: While holding the key
lock switch in the ACCESSORY position, gently
slide the ignition switch down (away from steering
wheel) to remove slack from switch. Tighten attaching screws. Do not allow the ignition switch to
move from the ACCESSORY detent position.
Because the ignition switch and the headlamp dimmer switch share the same two mounting screws, one
of the screws must be removed from the ignition
switch. This must be done after the ignition switch
has been adjusted and before the dimmer switch has
been installed. Remove one screw. Do not remove
the stud/nut.
(7) Install the headlamp dimmer switch as follows:
Slip switch into actuator rod and position over the ignition switch. Install screws finger tight. Remove the
dimmer switch actuator rod securing-tape from steering column.
(8) Adjust dimmer switch as follows: Depress the
switch slightly and insert a 3/32-inch drill bit into
the adjustment hole (Fig. 1). This is done to prevent
horizontal switch movement.

(9) Move switch toward steering wheel to remove
any lash from switch actuator rod. Tighten dimmer
and ignition switch fasteners to 4 Nzm (35 in. lbs.)
torque.
(10) XJ models: Install the lower instrument panel
trim assembly. YJ models: Install the windshield
wiper intermittent control module and its bracket (if
equipped).
(11) Install the negative battery cable.
Test dimmer switch. Test ignition switch operation
in all switch positions. If equipped with a tilt steering column, test operation of dimmer switch and ignition switch in all tilt positions.
