I just got done installing GM fog lights on my '12 Eco and figured I would share how to do it without removing the front bumper. There are a couple other how-to's on this site that show how to do it by removing the bumper. For me that just wasn't an option, and IMHO is overkill. I am going to apologize for the bad picture quality up front. All I had was a cell phone to take pictures with.
Parts 1 through 7 are mainly concerning how to install it without removing the bumper. The remainder of them are generic to any fog light install.
You will need;
- T20 torex (for the front splash shield).
- Wire cutters/fork/something with a small edge to take the plastic inserts off.
- Philip screw driver.
- Small ratcheting wrench + 10mm + 1/4in sockets + 3in extension.
- Car ramps or a lift. I used wood ramps.
- Fog light kit (of course).
- Small hands is a plus.
make sure you disconnect the negative battery terminal, and the car is safely
secured on the ramps or lift. I am not taking any responsibility for anything that happens to you or your car (or anything else) from following this.
1. Remove the front splash shield under the radiator.
There are a bunch of T20 screws that hold the front of the shield on highlighted in blue
. These are easy to take off. There are 2 in the center that do not need to come off but I took them all off anywho.
The line in red
are the plastic inserts. I used a flat head screw driver to get them started, then a wire cutters to get on both sides and pulled. They pop off pretty easily.
colored lines will need to come off also, but I did those later when I was installing the fog lights.
Lastly, the yellow
arrow is the direction to pull to remove it. It should be self explanatory once you are doing this yourself. Basically just pull down and to the back of the car.
2. Remove passenger side non-fog light insert.
Once the shield is off I started with the passenger side first because it looked easier (and was). Removing the original non-fog light inserts was kind of tricky, but once you get a look at it things make sense. There is one screw holding it to the bumper. The 3" extension helped with getting more swing on the wrench.
3. Install the passenger side fog light.
This is pretty straight forward. Re-insert new fog light cover the way the non-fog light one came out. Once the insert is in place the actual fog light can be fitted. The fog light will slide right up there no problem. Once in there you can tighten down the two screws that go on the same side, or towards the center of the car, to hold it there while you get the third on the far outside. I used a wrench with a 1/4" socket and philips bit.
This step is where the small wrench comes in handy with an extension. The outside screw is in a place that is hard to reach, but it is doable (more doable than the driver side). This is also where I removed the screws/plastic inserts on the green line from the first picture. That allowed me to pull the extra plastic flat down (which is also part of the wheel well plastic) so I could get more of my arm behind the fog light.
Here it is installed.
4. Remove the driver side non-fog light insert.
It will come off the exact same way as the passenger side. For the temperature sensor I used a 10mm deep socket and pushed/gyrated it around the front side of the panel to pop the temperature sensor free.
5. Insert the driver side fog light.
The front panel and temperature sensor are another straight forward install, especially if you did the passenger side already.
The trouble comes from trying to screw in the outside far screw to secure the fog light to the bumper. This is where small hands is useful, and you will
have to remove the screws/inserts in green from the first picture for this side. You just won't have enough arm room to get at the screw otherwise. I can't really explain how I got my hand up far enough, let alone with a ratchet, so I took a picture. Once all 3 screws are in you are finished installing the fog lights, and then on to the harness
6. Install the harness.
The harness is routed around the front of the car, next to the rest of the wiring that goes to the passenger side. There is a hole on the passenger side that the wire goes and drops down to the fog light.
The driver side has to go behind the headlight and the fuse end splits to the fuse box.
I attached the ground to one of the 3 posts that are to the inside of the driver side headlight. Then go back to the fog lights and plug them in.
7. Reinstall the splash shield
You should be done underneath the car now. Reinstall the shield the way it came off.
8. Install the switch.
Easiest part of the whole thing. Pop the fuse panel cover off below the switch and push from behind. Replace with the new switch. Sorry, no picture
9. Install harness to the fuse block.
Take the fuse cover off. The fuse you want is #48, 15A. There are three large stainless screws holding the whole thing down. Once they are loose you can wiggle the top portion off by unsnapping it from the 6 tabs on both sides. The fuse block top then wiggles off and you should see a bunch of holes where the fuse tabs would slide in to. There is only one end of fuse 48 present, and by comparing to the backside of the top you can figure out where it is suppose to go. The harness plug can be stubborn to get in the fuse block. I used a pointed needle nose pliers to make sure it was in all the way. Once finished, reverse the process to reinstall the fuse block. Again, sorry, no picture.
10. Do one last sanity check, connect the battery terminal you took off, and test them out
Hope this helped!
