Ignition Switch Mechanical Test

Test the mechanical operation of the ignition switch by rotating the ignition switch lock cylinder through all positions. The movement should feel smooth with no sticking or binding. The ignition switch should return from the START position back to the RUN position without assistance (spring return). If sticking or binding is encountered, check for the following conditions:
^ burrs on the lock cylinder key
^ binding ignition switch lock cylinder
^ steering column shroud rubbing against ignition switch lock cylinder
^ burrs or foreign material around rack-and-pinion actuator in lock cylinder housing
^ insufficient lubricant on actuator

NOTE: Do not apply lubricant to inside of the ignition switch.
