REMOVAL & INSTALLATION



Standard Columns Without Air Bag
  1. Remove the steering wheel as previously outlined. Remove the trim cover.
  2.  
  3. Pry the cover off, and lift the cover off the shaft.
  4.  
  5. Position the U-shaped lockplate compressing tool on the end of the steering shaft and compress the lock plate by turning the shaft nut clockwise. Pry the wire snapring out of the shaft groove.
  6.  
  7. Remove the tool and lift the lockplate off the shaft.
  8.  
  9. Remove the canceling cam assembly and upper bearing preload spring from the shaft.
  10.  
  11. Remove the turn signal lever. Push the flasher knob in and unscrew it. On models equipped with a button and a knob, remove the button retaining screw, then remove the button, spring, and knob.
  12.  
  13. Pull the switch connector out the mast jacket and tape the upper part to facilitate switch removal. Attach a long piece of wire to the turn signal switch connector. When installing the turn signal switch, feed this wire through the column first, and then use this wire to pull the switch connector into position. On tilt wheels, place the turn signal and shifter housing in low position and remove the harness cover.
  14.  
  15. Remove the three switch mounting screws. Remove the switch by pulling it straight up while guiding the wiring harness cover through the column.
  16.  

To install:
  1. Install the replacement switch by working the connector and cover down through the housing and under the bracket. On tilt models, the connector is worked down through the housing, under the bracket, and then the cover is installed on the harness.
  2.  
  3. Install the switch mounting screws and the connector on the mast jacket bracket. Install the column-to-dash trim plate.
  4.  
  5. Install the flasher knob and the turn signal lever.
