Removing the turn signal switch from a Jeep Cherokee allows you to replace the switch. Along with the indicators, the switch module contains the dimmer switch for the headlights and the emergency flasher switch. This switch is mounted on the left side of the steering column under the plastic trim work. You must remove the steering column trim, the lower knee blocker panel and the water shield that protects the switch to remove it. All of these pieces are easily removed with basic hand tools.
Open the hood and locate the negative battery terminal. Remove the battery cable from the negative battery terminal with a wrench and set it aside so that it can not come in contact with the battery.
Remove the knee blocker panel below the steering column. You will find two screws near the top edge--remove them with a Phillips screwdriver and pop the lower section of the panel off the two retaining clips that hold it. Set the panel aside for now.
Locate the three mounting screws on the bottom of the steering column trim panel. Remove these three screws with a Phillips screwdriver and lift the upper and lower trim panel off the column.
Locate the turn signal switch on the left side of the column. The switch is retained with three screws that are installed through a black plastic water shield. Remove the screws and lift the switch lightly.
Locate the wiring harness connector under the switch. Unplug the two connectors from the switch and remove the switch from the column. It will lift right out of the column once the wiring harness connector is disconnected.
Disconnecting the negative battery cable from the battery should be done to disable the airbag capacitor. Allow the truck to sit for five minutes after disconnecting the battery before starting any work on the steering column. This will allow the capacitor to discharge and disable the airbags.
