All 1981 and later models utilize a combination switch in place of the previous turn signal switch. The combination switch, in addition to operating the turn signals, will also control the windshield wiper/washer functions and the cruise control if so equipped. Removal and installation procedures for the new combination switch are basically the same as those given for the turn signal switch.
REMOVAL & INSTALLATION
- Remove the steering wheel. Remove the trim cover.
- Pry the cover from the steering column.
- Position a 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.
- Remove the tool and lift the lockplate off the shaft.
- Slip the cancelling cam, upper bearing preload spring, and thrust washer off the shaft.
- Remove the turn signal lever. Remove the hazard flasher button retaining screw and remove the button, spring and knob.
- Pull the switch connector out of 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.
- Remove the three switch mounting screws. Remove the switch by pulling it straight up while guiding the wiring harness cover through the column.
- 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.
- Install the switch mounting screws and the connector on the mast jacket bracket. Install the column-to-dash trim plate.
- Install the flasher knob and the turn signal lever.
- With the turn signal lever in neutral and the flasher knob out, slide the thrust washer, upper bearing preload spring, and cancelling cam onto the shaft.
- Position the lock plate on the shaft and press it down until a new snapring can be inserted in the shaft groove. Always use a new snapring when assembling.
- Install the cover and the steering wheel.
