Turn signal

[Charley]

My daughter has 86 Buick Century. The passenger side rear blinker doesn't blink. The light is good. The front blinker, blinks. Any ideas.

Even though you said the light is good try changing the bulb, might be a bad bulb or try cleaning the contacts in the socket with the power off of course so you don't blow a fuse. If that does not work grab a tester and start looking for a short.

But the front blinker blinks/works.

I would check for power to the socket. If there is power than I would check the contacts inside of the socket and the contacts on the bottom of the bulb. If any of those are worn out, and they do, it could be the problem.

If there is no power to the socket than your going to have a lot of fun tracing wiring back to find the open circuit.

One more thing. She could make it blink my moving the the blinker lever up and down. That trick doesn't work anymore.
