Both of mine just quit working at the same time, but the third brake light still works..
Idk anything bout electrical stuff.. some one help me out.

 

Start with the simple stuff. Bulbs and fuses, once we're sure those are working we can talk.

 

It shouldnt be the bulbs, I mean the odds of them going out at the exact same time?
And what fuse should I check?

 

the headlamp fuse!?! just pop the fuse cover and check the diagram, not very hard

 

theres no need to be a dick. the guy said he didnt know much about electronics.

 

I didnt know it came off dickish, sorry.

 

He wasn't really being a dick. There's two places where there are fuses (fuse box and passenger's side floor), I doubt anyone knows off hand which fuse specifically they'd be.

 

apology excepted lol. i wasnt tryin to be a dick either, i just get tired of gettin on the board and see people asking for help, and guys who think they know everything and think they have the baddest cobalt around just run their mouth, not saying thats what your doing, just what this board is turning into.

 

O your a 05 member!, I know exactly what you mean, I use to be on here all the time, since 08. Perfectly understandable for the misconception.

Now back to your original broadcasting program

 

BUMP. Okay checked it all out, seems to be a issue with the lights themselfs. Stupid aftermarket crap.
Anyways where is the best place to get stock tails?

 

Should be a standard bulb just bring it to your local auto store/they can look up the type and you will be set

 

thats odd tht both would go out at the same time? but no matter, bulb size is 3157

hope this helps man

 

Just an FYI if your car isn't on the tails wont work but the third will. So by saying this turn the car on then check it out might be amazed. Stumped me for awhile too.

 

The odds are NOT zero. I mean, if they were put in at the same time in the factory, then they both have the same number of cycles, and hours on them.
Its possible they burned out one at a time and you didn't notice until they were both burned out.

That happened to my dad once on his pickup truck. He had got ready to go to work, started his truck up, one headlight burned out right at turn on, then she started to drive and before he got out of the garage the other light went out.

So ya, check the light bulbs first Always start simple.
