Turn Signal Switch

REMOVAL & INSTALLATION
1964–66 Chevelle

NOTE: When servicing any components on the steering column, should any fasteners require replacement, be sure to use only nuts and bolts of the same size and grade as the original fasteners. Using screws that are slightly too long could prevent the column from the collapsing during a collision.

  1. Disconnect the negative battery cable.
  2. Matchmark and remove the steering wheel. Refer to the procedure earlier in this section.
  3. On column shift cars, remove the shift lever retaining pin and the lever.
  4. Disconnect the column wiring harness from the chassis harness.
  5. Remove the lower trim plate and the upper mast jacket clamp.
  6. On automatic cars, remove the indicator retaining screw and the pointer.
  7. Remove the three turn signal-to-housing screws.
  8. Remove the turn signal switch, housing, and shift bowl from the steering column. Separate the switch from the wiring harness.

To install:

  1. Engage the switch to the wiring harness, then install the turn signal switch, housing, and shift bowl to the steering column.

NOTE: Two different switch assemblies are used. Although the removal procedures are the same, the parts are not interchangeable.

  1. Install the three turn signal-to-housing screws.
  2. On automatic cars, install the indicator pointer and retaining screw.
  3. Install the lower trim plate and the upper mast jacket clamp.
  4. Connect the column wiring harness to the chassis harness.
  5. On column shift cars, install the shift lever and retaining pin.
  6. Align the marks made earlier and install the steering wheel.

  6. Slide the cancelling cam, spring, and washer off the shaft.
  7. Remove turn signal lever.
  8. Push the four-way flasher knob in and unscrew it.
  9. Remove the three switch mounting screws.
  10. Pull switch connector out of the bracket and wrap it with tape to prevent it from snagging. Connect a length of twine or mechanic's wire to the connector. When the connector is pulled through the column, leave the twine or wire in the column in order to pull the new switch harness into position during installation.
  11. If applicable, place tilt columns in the low and remove the harness cover.
  12. Remove the switch and harness assembly from the steering column.

To install:

  1. Install the switch and harness assembly to the steering column. Use the length of twine or wire to pull the harness through the column and into position.
  2. If applicable, place tilt columns in the low and install the harness cover.
  3. Install the switch connector to the bracket.
  4. Install and tighten the three switch mounting screws.
