Replacing Turn Signal Assembly-Fog Light failure

Maybe others can use this. My fog lights quit working. Search on this forum turned up lots of hits about relocating the wiring to a simple switch, but I may be selling. I read through the FSM and took it apart. Auto Zone had the part for $50. It's easy and fast. Maybe not as cheap as a little switch and some wire, but it keeps the jeep OEM. Here goes...
  • You need a torx set. The Harbor Freight set has all the sizes needed. One is really small. You also need a long skinny phillips and a flat blade. A Volt, Ohmeter will also help diagnose the failure. Harbor Freight has one really cheap.
  • Check local availability of the part. I got lucky and found one in stock at Auto Zone. Make sure you specify w/fog lights.
  • Pull the covers. Release the steering adjust. You will be moving it and the wheel back and forth. Look under the steering wheel cover. Remove the two screws nearest the steering wheel. The cover should separate and come apart. Carefully pull the top first then bottom. You need to slide past the wheel adjust lever and off the ignition.
  • From above look down and locate the two wiring harnesses. One for the signal and one for the wiper. Using a flat blade screwdriver, move the red lock tab back toward the front of the vehicle. Press the tab down and wiggle it loose. Do both.
  • Remove the two screws from the top nearest the steering wheel.
  • Pull the assembly. It comes out with both turn signal and wiper. It looks like a set of handlebars.
  • Move to a table.
  • To check the switch, rotate to the back, right side up. Locate the connector on the back. Notice the pins are numbered. The bottom row starts with "11". The fog switch is on pins "13" & "14". They will have continuity if the switch is in fog light "on" position. If not, the switch is bad. If it's off and the two have continuity, it's shorted and also bad.
  • Remove the square relay in center in the back. Set aside.
  • Looking at the assembly from the front as if it were mounted in the car, locate the two small torx screws on the wiper side. Remove them.
  • The two halves should slide apart.
  • Slide the new one on, install the two screws and plug the relay back in.
  • On the old part, lubricate the rubber cover on both sides around the signal stem. Slide it off the stem carefully. Slide it on the new one.
  • Reinstall in reverse order.
Hope this helps.

Nice write up, if I may add something. Disconnect the battery first.

If your jeep has airbags, playing around a live system can lead to some unhappy results.
