Electrical or Alternator Problem?

I drive a 2007 cobalt ls coupe, 5 speed.
For a while now whenever my car is on, every light on the vehicle pulsates or flickers from bright to dim, literally every light. Dash, head unit, headlights, tail lights, side markers.
Is this contributed to a problem with the alternator? Or something electrical like a short or a loose connection? Or something totally different?
Any input is appreciated.

you could check your battery connections, but its probably your alternator going out. You could put your dmm on the battery and see if the voltages are fluctuating like crazy. Although it might be that the alternator is just barely keeping the battery charged, so look to see if your voltage seems low too

20/25 imp mpg

Welcome to the forum, pooptag.

If you wanted for me to check into anything for you as far as recalls or warranty information is concerned, or if you were planning on working with a dealership to get the electrical issue on your Cobalt checked out, please let me know. As you're new to the forum, I do not believe you can use the private messaging tool yet, but I can forward you my email address.

Battery conncetions are all good, and voltages are too. I heard something about cobalt alternators checking out good as well, until the are completely dead but I don't know. thanks though
