I have a 2008 Cobalt LS. My passenger side turn signal began working only intermittently, so after pulling it out & taking a look, I found that the socket connections were corroded. After some searching on this forum, I did find a post with the same issue, but with no responses.
Here is the original post:
"I recently had a bulb burn out and I replaced it and everything worked fine, that was about 3 months ago and now my left turn signal doesn't work at all. My right turn signal works and so I switched the bulbs in my right turn signal with the left turn signal and the bulb still works. So I know its not the bulb that burned out. After looking at the headlight I realized there was a good amount of water built up in the corner of my headlight and there was some condensation within the headlight. I went ahead and looked at the turn signal bulb socket and realized that it was wet and looked corroded. I tried cleaning it but to no avail it didn't work still."
I do also have the water issue as well. I can get the turn signal to work at times, but after fixing it & then driving around for awhile, it stops working again. The issue with mine is that the one metal piece inside the socket, that comes up the wall of the socket to meet the wire from the bulb snapped off, so I had to fashion a small piece of metal to put in there to get it to work part of the time.
Here's my concern, I have searched everywhere online & even called places, including both retailers and salvage yards, and no one has the right socket for my car. Where would I be able to find this particular part? Again, it's the right-side (passenger) turn signal bulb socket (the one that faces forward, as I know there is a smaller one that faces to the outside).
Any advice/information would be extremely appreciated. Thank you.
