Q: I need advice on how to troubleshoot a mechanical or electrical problem? on 2008 Chevrolet Cobalt

My front right turn signal bulb does not blink or flash. I checked the fuses, relay and bulb. All of those items are okay.

First thing to do is install a new 3157 bulb to be SURE that's NOT your problem!! ... 'After' you have done this......Post results for more info...
I have already installed another bulb. The right flasher indicator on the dashboard blinks fast. I have also checked the fuses and the relays.
That's a different story than before!!!.... Check the GROUND at the bulb socket... That's the problem!! Can also be in the rear bulb socket!!
