turn signal short?

[Turbolaser4528]

I searched and couldn't find what I was looking for.

My front left turn signal bulb will not light up, but the right one does fine. All of my lights and signals work fine except for the front left turn signal. Now the left turn signal blinks fast because the bulb is inoperational. (Also, I put brand new bulbs in so that's not the problem)

The wires coming from the bulb look okay, and there's no obvious signs of wires touching where they shouldn't be.

I need to know how to get this bulb working again, and what to do to make it happen. Thanks a lot guys

Take a probe and check to see if your getting power out of the wire.

Also maybe check fuses.

Check if the bulb's ground wire (usually black) is still making good contact with the body. Also look for corrosion in the bulb socket contacts especially ground.

Allright, one question though; where do I look to check if the ground is making good contact with the body? The wire dissapears into a large tunnel of wires so I can't follow it.

I have read that there is some sort of black box by the ecu, but all I see is a bronze box with plugs going into it. Looks like a mini ecu or something. I don't know..

I had the exact same problem a little while ago.
On mine, it ended up being the socket the bulb is in. Try unplugging the bad one and switching it with the other side.

First fill out your vehicle profile so we know what DSM you have.

Connect a ohmmeter (in a multimeter) from the body to the ground contact in the bulb socket to see if there is continuity. You can also check if there is voltage (to ground or battery negative) on any other bulb socket contact when you put the turn signal on. If no voltage on contact (or no continuity) stick a safety pin thru the wires insulation into the wire to see if voltage (or continuity) is in the wire. If in the wire but not at the bulb socket's contact, the socket is faulty.

Yes the bulb sockets on DSM's tend to corrode or break contact easily so check it. Swapping is a good technique if you can.
