no dash turn signal lights

[cincymoto]

any ideas on why neither turn signal lights come on? If not it's going to be fun tracing through a wiring diagram. also, my right signal won't click into position, I have to hold it up. any help is appreciated! They both work outside.

silly question. have you checked the lamps too see if they are burned out?

what truck are you working on? electrical systems vary by year breaks, 83 - 86, 88 - 91, 92 - early 94, late 94 - 97

whoops... 86 f250, both lamps burned out w 89k miles? what are the odds on that. but you're right, should start there I guess but I doubt that's the issue. I've worked with hundreds of vehicles, I see 2000+ vehicles a week at auctions, never seen a signal light burn out yet. anythings possible. Reminds of Carl in Slingblade when the shop is stumped on a tiller and Carl says "It aint got any gas in it".

The turn signal switch under the wheel in the column has a bad/broken tap causing you to hold it up for right turns. Pull the instrument panel cover and look at the bulbs, their wires and go from there.

Huh. 2000/5=400 a day. 400/6=66/Hr. That's 1 vehicle every minute. Bet ya missed a few.

Broken turn signal = pull the steering wheel.

I must be magical, other than my current lincoln that uses LEDs. Every vehicle I've owned has burned one out.
