How to Repair the Turn Signal Switch on a 1994 Wrangler

Save

The turn signal switch on a 1994 Wrangler is housed inside the steering column. The switch is connected to a detachable stalk that controls the switch. Over time, the connectors on the switch can wear, causing the switch to activate when the stalk isn't moved, or the signal may fail to activate when the stalk is moved up or down. Although the individual components of the switch can't be repaired or serviced, the switch itself can be replaced. You can accomplish this task yourself if you have the right tools.

Things You'll Need

  • Wrench set
  • Socket set
  • Marker
  • Steering wheel puller
  • Lock plate removal tool
  • Flat-head screwdriver
  • Phillips screwdriver
  • Torque wrench
  • Detach the negative battery cable from the battery terminal by loosening the terminal nut with a wrench.

  • Pull the horn pad away from the steering wheel using both hands to remove it. Unplug the electrical connection to the horn switch.

  • Unscrew the steering wheel retaining nut with a socket wrench. Mark the relationship of the steering wheel to the shaft with a marker to simplify the task of reassembly. Remove the three exposed screws with a Phillips screwdriver and pull the horn contact components from the shaft, keeping them in order for later reassembly. If you are unable to pull off the steering wheel by hand, use a steering wheel puller. Align the center bolt on the puller with the steering wheel shaft. Turn the center bolt of the puller with a socket wrench to detach the steering wheel from the shaft.

  • Unplug the electrical connector from the turn signal switch.

  • Depress the lock plate using a lock plate removal tool. Then, pry out the retaining ring with a standard screwdriver. Pull the lock plate, canceling cam and bearing spring from the housing.

  • Remove the turn signal switch actuator arm screw, located on the left side of the switch housing, using a Phillips screwdriver. Remove the three screws hold the turn signal switch with a Phillips screwdriver.

  • Unscrew the screws holding the center-instrument-cluster bezel in place. Pull the bezel away from the instrument cluster.

  • Unscrew the bolts and nuts holding the steering column in place with a socket wrench, then lower the steering column. Lift the turn signal switch out of the exposed opening.

  • Feed the new turn signal switch and wiring harness through the opening in the steering column. Install and tighten the actuator arm screw and the retaining screws on the turn signal using a Phillips screwdriver.

  • Lift the steering column back into position and install the mounting bolts and nuts with a socket wrench.

  • Push the instrument cluster bezel against the instrument cluster and then install the retaining screws with a Phillips screwdriver.

  • Press the canceling cam and bearing spring against the turn signal switch. Then, place the lock plate over the cam and spring. Depress the lock plate with the lock plate tool and press in the retaining ring with a flat-head screwdriver.

  • Plug the electrical connector into the turn signal switch.

  • Place the steering wheel over the shaft and use the marks made previously to align it correctly. Install the hub nut washer and hub nut with a torque wrench, tightening the nut to 25 foot-pounds.

  • Place the horn contact components back onto the shaft and hold them in place by installing the three retaining screws with a Phillips screwdriver. Plug in the electrical connector to the horn switch.

  • Push the horn pad over the horn contact components with both hands.

  • Attach the negative battery cable to the battery terminal with a wrench.
