Volvo Coupes/Sedans/Wagons 1970-1989 Repair Guide

Combination Switch (Windshield Wiper Switch/Turn Signal Switch)



See Figure 1

This procedure requires removal of the steering wheel. If the vehicle is equipped with the SRS (airbag) system, refer to the safety precautions listed earlier in this section. DO NOT remove the wheel until these precautions have been followed.

  1. Turn the steering wheel to the straight ahead position.
  3. Remove the center pad from the wheel.
  5. Remove the steering wheel retaining bolt. If possible, matchmark the wheel and steering shaft. If the vehicle is equipped with SRS, pull out the locking screw and the long tape label from its station in the steering wheel hub. Use the lock screw (with the tape flag attached) to lock the contact reel through the hole in the steering wheel hub. Do not turn the steering wheel once the bolt is removed; the pin in the contact reel will shear.
  7. Remove the steering wheel and the upper and lower steering column casings.
  9. To remove the wiper switch, simply remove the screws holding it to the column and unplug the connector. The turn signal switch is on the opposite side and is also held to the column by two or three screws.

To install:
  1. Check the position of all the wires so that nothing is pinched in the casings.
  3. Reinstall the column casings and then reinstall the steering wheel. Check that the steering wheel position is true to the position of the wheels. If the vehicle is SRS equipped, do not turn the steering wheel until the center bolt is reinstalled and tight; doing so will shear the pin in the contact reel. Remove the locking bolt with its flag and store it in the extra hole on the left side of the wheel.
  5. Tighten the steering wheel bolt to 24 ft. lbs. (32 Nm).Reinstall the center pad.
  7. If equipped with the SRS system, make the necessary connections to reactivate the system.
