there are two resistors inside the ignition switch.

KEY-IN IGNITION SWITCH
The key-in ignition switch is integral to the ignition switch, which is mounted on the left side of
the steering column, opposite the ignition cylinder. It closes a path to ground for the instrument
cluster chime warning circuitry when the ignition key is inserted in the ignition cylinder and the
driver door jamb switch is closed (driver door is open). The key-in ignition switch opens the
ground path when the key is removed from the ignition cylinder.
The key-in ignition switch cannot be repaired and, if faulty or damaged, the entire ignition switch
must be replaced. (Refer to 19 - STEERING/COLUMN/IGNITION SWITCH - REMOVAL).
DIAGNOSIS AND TESTING - KEY-IN IGNITION SWITCH
19 - STEERING
1. Disconnect and isolate the battery negative cable. Remove the steering column shrouds. Unplug
the key-in ignition switch wire harness connector from the ignition switch.
2. Check for continuity between the key-in switch sense circuit and the left front door jamb switch
sense circuit terminals of the key-in ignition switch. There should be continuity with the key in
the ignition cylinder, and no continuity with the key removed from the ignition cylinder. If OK, go
to STEP 3. If not OK, replace the faulty ignition switch assembly.
3. Check for continuity between the left front door jamb switch sense circuit cavity of the key-in
ignition switch wire harness connector and a good ground. There should be continuity with the
driver door open, and no continuity with the driver door closed. If OK, see the diagnosis for
Instrument Cluster in this group. If not OK,
repair the circuit to the driver door jamb switch as required.
