Ignition Switch Mechanical Check

Ignition Switch Mechanical Check
Test the mechanical operation of the ignition switch by rotating the lock cylinder through all switch positions. The movement should not stick or bind and should return from the START position back to the ON position without assistance (spring return). If sticking or binding is encountered, check for the following:
^ burrs on the lock cylinder key.
^ insufficient lube on the lock cylinder.
^ bent or damaged ignition rod.
^ object rubbing against the ignition rod.
^ excessive rubbing of the actuator against the transmission shift socket.
^ binding lock cylinder.
^ shroud rubbing against the lock cylinder.
^ burrs or foreign material around the rack and pinion actuator in the lock cylinder housing.
^ insufficient lube on the actuator. (Do not apply lubricant to the inside of the ignition switch.)
^ binding ignition switch.

If the steering wheel lock is engaged with the wheels loaded against a curb, high effort will be necessary to turn the key from LOCK. Turn the steering wheel to either side of the lock to unload the system.
