COLUMN COMPONENT SERVICE
The Acustar columns have been designed to be ser-
viced as an assembly; less wiring, switches, shrouds,
steering wheel, etc. Also most steering column com-
ponents can be serviced without removing the col-
umn from the vehicle. For additional information on
electrical components refer to Group 8, Electrical.
IGNITION SWITCH SERVICE
TEST AND REPAIR
If the ignition switch effort seems to be excessive
due to binding. Follow the procedure outlined below
to determine the cause.
When service procedures are performed on the
Acustar steering column there are certain areas of
the column that can not be tampered with. If a prob-
lem related to these areas of the steering column are
detected. The entire steering column (less the remov-
able components) should be replaced see (Fig. 1 and
2).

(1) Remove the ignition switch from the steering
column. Refer toGroup 8D Ignition System.
(2) Using a key cylinder, check the turning effort of
the switch.
²If the ignition switch binds look for the following
conditions.
(1) Look for rough areas or flash in the casting and
if found remove with a file (Fig. 2).
(2) Remove the link and slider.
(3) Check the link to see if it has been bent and if
so replace with a new part.
Put the slider in its slot in the sleeve and verify a
loose fit over the length of the slot. If the slider binds
in the slot at any point lightly file the slider until
clearance is achieved.
²If no binding is found.
Lightly file the ramp on the ignition switch, (The
ramp fits into the casting) until binding no longer oc-
curs.
AUTOMATIC TRANSMISSION SHIFTER/IGNITION
INTERLOCK MECHANISM
The automatic transmission Shifter/Ignition Inter-
lock, is a cable operated system. It interconnects the
automatic transmission floor mounted shifter to the
steering column ignition switch (Fig. 1). The system
locks the shifter into the PARK position. The Inter-
lock system is engaged whenever the ignition switch
is in the LOCK or ACCESSORY position. When the
key is in the OFF or RUN position the shifter is un-
locked and will move into any position. The interlock
system also prevents the ignition switch from being
turned to the LOCK or ACCESSORY position (Fig.
2). Unless the shifter is fully locked into the PARK
position.
