4x4Wire - Ignition Switch Replacement
There are two sections to the ignition switch assembly. The front portion is the key tumbler lock mechanism and the rear portion is the electrical switch part. I found the electrical switch is readily available through most auto parts stores, though it may need to be ordered from the warehouse. The ignition switch and small harness also include a small plunger switch that is used to sense when the key is in the tumbler. This drives the little warning buzzer when you open the door with the key left in the ignition. Replacing the switch is fairly straight forward. Here is how I did it.
Removal of the lower dash panel. Removal of bolts securing column. Column dropped for access.
I first pulled off the small plastic cover over the key tumbler in the dash. I then removed the four phillips screws and one bolt securing the lower dash panel under the steering column. Next, I removed the two nuts and three bolts securing the steering column to the dash frame. This allowed me to drop the column down, providing access to the electrical ignition switch behind the key tumbler assembly. Be careful not to put undue strain on any wires running under the column.
Removal of key sense switch. Removing switch assembly screw. Switch assembly installation. Installing key sense switch.
Two screws secure the key sense switch to the housing that holds the key tumbler and ignition switch. I removed these and the one screw in the back that secures the ignition switch body. Finally, I unplugged the 8-conductor connector at the wiring harness. Installation of the new ignition switch goes in reverse order of removal, as does the dash reassembly.
