Replace the ignition switch on a 1970 AMC Rebel Machine, which involves accessing the switch through the steering column and replacing the electrical component that controls ignition and accessory circuits.

Warnings

Tools required

Parts

• Ignition switch assembly × 1 — Use OEM specification
• Steering column connector (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery cable and secure away from battery post
3. Allow engine to cool completely if recently driven
4. Position driver's seat fully rearward for maximum working clearance
5. Gather all tools and parts within easy reach

Procedure

1. 1

   Remove lower steering column trim
   Locate and remove the screws securing the lower steering column cover/trim panel. On the 1970 Rebel, there are typically two to three screws at the bottom of the column shroud. Carefully pull the lower trim piece away from the column and set aside. Note any wiring clips or guides attached to the trim.
2. 2

   Access ignition switch mounting area
   With the lower column cover removed, locate the ignition switch mounted on the upper side of the steering column tube, just below the instrument panel. The switch is connected to the lock cylinder via a rod linkage. Identify the electrical connector attached to the back of the switch.
3. 3

   Disconnect electrical connector
   Press the retaining tab on the ignition switch electrical connector and carefully pull it straight off the switch terminals. The connector may be stiff from years of service - wiggle gently while pulling if needed. Note the connector orientation for reinstallation.
4. 4

   Note actuator rod position
   Observe the position of the actuator rod that connects the lock cylinder to the ignition switch. The rod should be in the 'OFF-LOCK' position with the key removed. Note how the rod engages with the switch slider mechanism before removal.
5. 5

   Remove switch mounting screws
   Remove the two screws that secure the ignition switch to the steering column jacket. These are typically small pan-head screws accessible from below the column. Hold the switch as you remove the second screw to prevent it from falling.
6. 6

   Remove old ignition switch
   Carefully slide the ignition switch off the actuator rod and away from the column. Note the orientation of the switch and how the actuator rod engages the slider. Inspect the rod for wear or bending - replace if damaged.
7. 7

   Prepare new ignition switch
   Position the new ignition switch slider to the 'OFF-LOCK' position (typically marked on the switch body or fully pushed in one direction). This must match the position of the actuator rod for proper installation and operation.
8. 8

   Install new switch
   Align the actuator rod with the slider slot in the new ignition switch. Carefully slide the switch onto the rod and position it against the steering column jacket, ensuring the mounting screw holes align. The switch should seat flush against the column.
9. 9

   Secure switch to column
   Install the two mounting screws and tighten them evenly and firmly. Do not overtighten as this can crack the switch housing or strip the column threads. The switch should be snug against the column with no movement when actuated.
10. 10

    Reconnect electrical connector
    Push the electrical connector firmly onto the switch terminals until the retaining tab clicks into place. Ensure the connector is fully seated - a partially connected switch will cause intermittent electrical problems or no-start conditions.
11. 11

    Test switch operation before reassembly
    Temporarily reconnect the battery negative cable. Insert the key and test all ignition switch positions (OFF, ACC, ON, START). Verify that accessories function in ACC position, dashboard lights illuminate in ON position, and starter engages in START position. Disconnect battery again before proceeding.
12. 12

    Reinstall steering column trim
    Position the lower steering column cover back onto the column, ensuring any wiring clips or guides are properly seated. Install and tighten all trim screws. Verify the trim does not interfere with steering column movement or switch operation.

Reassembly

1. Reconnect battery negative cable and tighten securely
2. Verify all electrical connections are secure and properly routed
3. Ensure steering column trim is properly aligned and all fasteners are tight
4. Return driver's seat to normal operating position

Verification

• Turn key to ACC position and verify radio and accessories operate
• Turn key to ON position and verify all dashboard warning lights illuminate
• Turn key to START position and verify engine cranks and starts
• Verify key returns to ON position when released from START
• Test that key can be removed only in OFF-LOCK position
• Verify steering wheel locks when key is removed and turned to LOCK position
• Check that all accessory circuits (radio, heater blower, etc.) function in their designated switch positions
