2000 328i parking light/turn signal problem

So last night I turned my car on and noticed my front drivers side parking lights/turn signals weren't working. I picked up a new bulbs and threw it in. It still didn't work so I checked the socket and it's perfectly fine. Checked the fuse box for any possible blown fuses and they're all good. Wiring seems good all around, so I have no clue what else it could be and haven't had much luck in finding anything else on this issue. Any help would be appreciated *2000 328i pre facelift, if that matters*

A VERY common problem is with the turn signal sockets.

They visually appear fine, no corrosion or obvious problems, but you need to understand what happens to the sockets.

There is a small plastic disc the bulb base goes through and this disc hold the blub tight against the terminals in the base of the socket.

The disc snaps in a groove in the socket and for what ever reason over time the body of the socket expands and the disc pops out of the groove. All you have to do is try to wiggle the light bulb or shake the socket and if the bulb is loose, then this means the terminals at the base of the socket are not in solid, spring contact with the bulb.

You can push the disc back into the groove with your pinky or a small deep socket until it snaps back in place, then you will need to use some plastic glue to put a small bead around the inside edge of the disc/socket interface.

This is how I have repaired a bunch of these sockets, but you also have the option of purchasing a new socket.

Okay I'll definitely be purchasing a new socket, then, but my passenger side just went a little less than an hour ago. Is this just coincidence or could I be looking at a different problem?

You need to pull the bulbs out and make sure the bulbs are not the issue, you may have one bad socket and a bulb failure or you could have 2 bad sockets.

The bulbs should be very snug in the sockets. Very, very, very simple to check, but very hard to explain in writing.

The bulb should not be loose at all, you will know if the disc is loose, I just snap be disc back in the grove and put a small bead of plastic glue around the inner edge of the disc. I do not use Krazy Glue, but something like a model glue.

But make sure the problem is loose bulbs.
