Ignition Switch Mechanical Check
WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
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.
- 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.
- Binding ignition switch.
CAUTION:
Do not apply lubricant to the inside of the ignition switch.
