Turn Signal (Combination) Switch

REMOVAL & INSTALLATION



The individual switches within the combination switch are individually replaceable after the combination assembly is removed and disassembled. It is not difficult but is exacting, requiring careful removal of wire terminals from the multi-pin connector.

  1. Insure the ignition is switched OFF .
  2.  
  3. Remove the steering wheel pad and remove the steering wheel. Use of a steering wheel puller is strongly recommended. Always scribe matchmarks on the wheel hub and the steering column so the wheel can be reinstalled straight.
  4.  
  5. Remove the upper and lower steering covers. Remove the retaining screws holding the combination switch to the column.
  6.  
  7. Trace the harness down the column, and then unplug the connector. Release the harness from the harness clamp(s).
  8.  
  9. Remove the combination switch from the column and place it on the workbench.
  10.  
  11. Disconnect the air bag harness (if equipped).
  12.  
  13. On the newer models, you will be able to remove the two mounting screws retaining the arm (wiper etc.) to replace.

  1. Otherwise, identify the component to be replaced. Identify each wire color running from the switch (to be replaced) to the connector. These wires (only) will need to be removed so the new ones can be installed.
  2.  
  3. On all but 198990 Land Cruiser, the cover on the back of the connector must be raised to allow the wire terminal to be removed.
  4.  
  5. Diagram each wire and terminal to be removed. The new wiring must be installed exactly as original. From the front or plug end, insert a small pick or probe between the locking lug and the wire terminal. Pry down the locking lug with the tool and pull the terminal out from the rear. Repeat the procedure for each wire from the switch to be replaced.

  1. With the wires free, remove the retaining screws holding the switch to be changed and remove it. The lighting control stalk has a spring and small ball with it; do NOT lose them.
  2.  

To install:

  1. Assemble the new component(s) onto the switch. Retaining screws should be tight enough to hold but not over tight. Components with cracked plastic will NOT stay in place.
  2.  
  3. Track the new wires into the harness and place each wire loosely in its correct terminal socket.
  4.  
  5. Use the removal tool to push on the back of the terminal (NOT on the wire) and force the terminal into the connector. Each terminal must be pushed in until it overrides the locking lug. Test each one by gently pulling the wire backwards; it should be positively locked in place.

  2.

  4.  
  5. Align the matchmarks and reinstall the steering wheel and pad.
  6.  
  7. Turn the ignition switch ON and check the function of each control item.
