I copied this from an earlier question:

What could be wrong with brake lights, if not the switch, bulbs, or fuses?

The brake lights have stopped working in my Ford Explorer. The bulbs are new, the brake switch is new, the fuses are not blown. What else is there to check?

You need to find where the power stops. Use a test light at the sockets. If no power, go to the wire to the socket. When you find where power goes in but doesn't come out, you have your answer. Assuming there is one answer. There is also a possibility of a ground problem. Good luck.

It could be one of many possibilities. I had a brand new s-10 that I was working on and it would blow out the fuse at weird times. I ended up chasing it down to a bolt that was left under the carpet from the factory. the bolt had rubbed through the wire and would short out and pop the fuse.. sometimes electrical problems can be a bear......

A car that shuts off when the turn signal is used indicates a major short in the electrical system. When the turn signal is used, it cause a massive draw on the power and shuts it down.

A short in the turn signal switch or the wire in the steering column is shorted. There is more likely a short in one of the bulbs. easy to find remove bulbs until the bad one is found then replace

A short in either the multifunction turn signal switch or a short in the wiring harness going to the switch.

The turn signal relay is underneath the dashboard on the drivers side in the fuse box. If you are looking for the acutal turn signal its on the steering column.
