I just added fog lights to my Cobalt LT by tapping in to the fog light fuse under the hood and connecting the factory fog light switch on the dash (the harness was behind the trim). It works beautifully, but the fog light indicator on the instrument panel does not light up when the fogs are on. Does this require a reprogramming of the car computer to let it know it now has fogs? Or did GM set up the wiring so the indicator goes on only if you have factory fog lights? Anyone know?

 

Button works if you just run power to fuse location? cool my 05 ls i just ran its own wires to its own switch.

 

do all cobalts come prewired for fog lights??? I have an 06 LT and want a bumper with fogs.....maybe SS.

 

My Cobalt did not have wires to attach the factory fog lights. There was a wire for the fog light switch behind the dash trim next to the interior light switch.

I had bought a replacement trim with the fog light switch in it, and when I connected the switch and pressed it, I heard clicking near the fuse box, so I knew it was switching on/off something. So I just bought aftermarket fog lights and connected them to the fog light fuse and viola... fog lights work. Just no indicator symbol in the instrument panel. (I can see the indicator symbol on the panel but it doesn't light up.)

By the way, I didn't think it was worth spending all that money for a new bumper, grilles, fog lights, harness, etc. ... just to get fog lights. This mod cost me $20 for the trim with the switch and $35 for the fogs.

 

Thanks for the reply. I got my balt a week ago and im new to the forum. will introduce myself formally, once i take some pics. Im a newbie with cars, and desperate to learn all i can about the car. But......I need a new bumper anyway....thats the only thing that needs to be replaced on my balt. fitment terrible around one light, and paint on one side looks darker than should be. Good to know all balts not prewired....but i do want a bumper with fogs.....not sure what kind i want yet though.....thanks for the info! ill look into this further.....

 

Yea its not your bumper that fitment issue happens with all of our cars. The fact that our bumper covers are plastic and the 1/4 panels are metal will make the paint almost impossible to match

I bought $20 fog light kit at autozone, along with i smaller $5 led switch. Mounted em behind the lower center grill. There are mounting holes for the bumper that i poped out and bolted the fogs in. Hardest part for me was aiming, extending the hot wire to the switch (only 2 feet long), and i havent mounted the switch yet (need a drill)

 

Shame on the fitment thing....I have read that before. That is gonna drive me a lil crazy!!!
Paint match problem makes sense.....but i also think there was some crapy body work on the car on just part of the bumper. ill post pics soon as i get em.....i also think some crap body work done because.....i got the car a week ago....had a clean carfax. but it looks like on my bumper it was touched up on one side.....and the alloy rims have like this lil spider effect on the rim....like maybe they were painted >(.... so def. besides tint bumper/fogs is next! thanks for ur help all............

 

im trying to find the fog light plug where the bulb plugs into mine got messed up and i cant find it anyone got a part number. if so pm meplz

 

pictures of lt with fog lights please

 

why is matching paint on the bumper so hard ? if your body shop cant match the paint on the plastic bumper to your 1/4 panel then you should find a new body shop

 

does every cobalt come wired for the fog light switch? or did they have 2 different harnesses for cars without power options. i have an 09 cobalt ls with power nothing and want to put fog lights on. i got an SS bumper and a factory fog light harness but i couldnt see a hook up for a factory fog light switch inside?? can anyone help??

 

Can someone post a picture of where this plug is at under there? If its in plain sight then I don't have it

 

It isn't.

If you look at a Mercedes or higher end car the plastic is identical.

It's cause ours are painted at different times with different batches of paint. they make a bunch of bumpers in the colour and put them on the cars. If you get your car repainted at one time with that batch of paint it should be identical.

Hi there, i recently did this same thing on my 09 Cobalt LT. The Fogs light up perfectly but no illumination on the Dash.
Did you ever get this resolved on your Cobalt?
