Why Don't My Turn Signals Work?

[jordanr]

Mia gives an overview of how turn signals work and then moves on to diagnostics. She explains how the wiring works. If none of the signals are working, then the problem is likely in this order:
* Fuse(s)
* Flasher
* Switch
* Wiring

If one or two signals are not working, then usually the bulb is the problem. Could be switch or bulb sockets or wiring but most likely is the bulbs.

Please feel free to share additional advise or what other common causes you have experienced.

I just viewed it, but with the sound off to avoid annoying my wife. I was quickly impressed by the sample wiring schematic and use of the yellow hi-lighter to show the circuit path of interest. I will look at the video again with sound on later today.

OK, I'm going to send PM to jordanr.

One of the turn signals won't work in my car and it turned out to be damaged bulb socket.
