Jeep JK multi-function switch replacement3
A multi-function switch, just as the name suggests, controls several different functions related to the lights of your Jeep. Using this one switch you turn on the headlights, fog lights, control turn signals, dashboard lights and dome lights. Unfortunately there might come a time when you notice that something about your lights doesn’t seem right. There could be a few different reasons for your lights or dash indicators to start acting strange. First thing you should always check is the light bulbs. Unless you have all LED lights, check your headlights and turn signals to make sure that all light bulbs work. You might have a fuse that is damaged and needs replacing. You can inspect the fuses an replace the damaged one.
The most common reason for your lights and turn signals not working properly is the multi-function switch failure. Over time some connections inside the switch might become loose and cause problems. You can inspect the switch lever and check whether it stays firmly in each position or if there is some play.
With loose connections, your dashboard lights, dome lights, fogs, or even headlights might randomly flicker or come on unexpectedly, which can be very dangerous. You might encounter problems with your turn signals as well.
The reason I decided to replace the multifunction switch on my Jeep, was due to the fact that my turn signals started acting strange. While turning right and activating the right turn signal by pulling the lever up, the left turn signal would come on first and flash once, and only after that the right turn signal would come on. It has been going on very randomly for the last couple of weeks and it started to drive me crazy, not to mention it was probably irritating other drivers behind me.
Another problem with the turn signal you might experience is that it doesn’t automatically shut off after you complete the turn. I have not personally have that problem, but I hear it is unfortunately a common issue.
Replacing a Jeep JK multi-function switch is a very easy and quick task. The procedure is the same for all 2007-2017 JK’s. The entire project should take about 30 minutes and you only need few tools. If you prefer to watch a video, here’s the best one I found on this subject.
Disclaimer: Like I always mention I am not a professional mechanic, I just try to do as much work on my Jeep as possible. It helps me learn more about my vehicle and save some money that can be spent on parts and upgrades.
I take no responsibility for any injury or breakage which might occur if you decide to follow these steps. You have to decide if you’re comfortable working on your Jeep. If you’re not, please have a professional do the installation for you.

Parts and tools needed:
1. Multi-Function Switch – this one includes fog lights, make sure you select one that works for you
3. T20 TORX screwdriver – you’re going to need a skinny screwdriver to reach the recessed screws
Prepare your tools and get everything ready before you start the project.
Get your new switch ready for installation, inspect the switch, make sure that all pins inside the two plugs are straight. When you plug in the connectors and the pins are bent in any way, there will be no connection established and your new switch will not work properly.
Disconnect the negative battery terminal. It will prevent any electrical short form occurring as well as prevent the air bag from accidentally deploying.
To gain access to the multi-function switch, both bottom and top parts of the plastic steering column shroud will need to be removed.
Using the T20 TORX screwdriver, remove three screws from the bottom part of the plastic shroud.

Push the steering wheel down and carefully remove top steering column shroud.
Using a Phillips screwdriver, remove screw holding the switch in place.
Gently slide the switch partially out.
Carefully remove the two connectors from the switch. Each one has a small tab you need to push down to remove it from the plug. Do not rush it and don’t force it out.
Set the old switch aside and grab the new one. Inspect the connectors and make sure nothing is bent, broken or melted.
Slide the new switch back into place. Make sure everything lines up correctly. Carefully plug in both connectors. Reinstall the Phillips screw.
