I have a 2008 chevy cobalt lt. The driverside tailight won't come on. No brake lights, reverse light, or turning signal. The bulbs were just replaced. I took an voltage meter to it and it seemed low. Fuses all check out. Any ideas?

Best to you.

change the front bulb

If the other brake and turn lights are working the brake light and flasher units are ok . With a test light check at the bulb holder terminal and bulb holder body, test light should glow ,if not check from terminal to a metal part of panel away from the light body . If test light now glows the brake light body has a bad earth if the test still not glowing the power cable to the light is broken.

Sounds as if the bulbs are bad, but could also be a failed multi-purpose switch.

you have 2 elements in the bulb. One for turn signal and lights, the other for the brakes. You have a bad bulb that needs to be replaced.

Sound's like its just a bulb problem, just make sure that you replace it with the correct bulb,,,

It is as simple as your hazzard switch needs to be replaced yes your hazzard switch as now turn signals are built threw the hazzard switch my PT Cruiser had same problem as my s10 replaced hazzard switch fixed the problem

Check tail light fuse might be blown

i think you'll find with a test light at the tail light connector,that the you do have power but the problem is the unit that holds the bulbs and is a printed circuit is bad

The bulb has two elements in it. one of them is probably blown.
