The first to go were your wipers, as they started to turn on by themselves or involuntarily splash water on your windshield. The week after, your turn signal lights won't switch on or off with the turn of its knobs. Now it's just a combination of problems-from your car's wipers to its headlights. No matter how hard you try to diagnose each part, you still can't find the root of the problem. Well, it's either you're just one unlucky car owner or you've got yourself a faulty combination switch. Take back thencontrol of your car's important functions and install a new combination switch with these 6 easy steps:
Required skill level: Novice
Needed tools and materials
- New combination switch
- Wrench set
- Steering wheel puller (optional)
Preparing your car for installation
Before attempting to install a new combination switch assembly on your car, we recommend taking necessary precautions. One safety precaution is disconnecting the car battery's negative cable from its terminal. Since the combination switch deals with some of your vehicle's electrical components, never skip this step to avoid grounding yourself or damaging your car's electrical wiring.
Locating your vehicle's combination switch
The combination switch is most often located within a driver's reach, such as behind the steering wheel. Once you've located the access panel to the switch at the back of wheel, proceed with removing the old switch to give way to the installation of the new part.
Removing the old combination switch
Remove the steering wheel to gain access to the panel of the switch. Now that the wheel is out of the way, you should be able to see the panel without any obstructions. Unscrew both covers found on the upper and lower part of the steering column. Find the three retaining screws found on the switch's assembly and remove them using a screwdriver. Get a hold of the switch assemblies and disconnect the wires connecting them to the car's electrical system. Remove both switches from the frame once they are disconnected from the wiring.
Installing the new combination switch
Take your replacement combination switch and connect it to the wire connectors from behind the wheel. Take note which wire should go with what part of your new switch to avoid wiring problems later on. Attach the wires using the three retaining screws removed earlier. Secure the new combination switch to the steering column and refasten the upper and lower covers.
Reassembling all other parts removed
Now that the new combination switch is safely resting on the steering column, reattach the steering wheel and all other parts removed during the process of removal. Reconnect the battery's negative cable to begin testing the new switches.
Testing the newly installed combination switch
Start your car and begin testing the switches. Make sure that the labeled switch activates the correct part or elicits the right response from the part to ensure that it is installed and wired correctly.
