No blinkers
What would cause the blinkers to not work? Replaced the relay already. I don't see any other fuses for the blinkers..??

Re: No blinkers
Blinker fuse is marked TRFK...
Also check switch plug on column is connected.... |
Re: No blinkers
Thanks, I'll take a look in a few min. Hard to see the writing on some of them, it's original.

Re: No blinkers
There was one fuse blown but it wasn't the one I was expecting. No telling what's going on in this fuse block. If I told you some of the things I've found...
I'll replace it and see what happens. What amperage should it be? |

It depends on which fuse it is. Here is one of the fuse blocks. LockDoc |
Re: No blinkers
That's what the block looks like. It was the one between Heat and Radio, I assume that's the heater fan. But I used the heater this morning on the way to work and it works fine. So like i said, who knows what they did under there. I'm looking at a whole new wiring harness too just in case. Probably best...

Re: No blinkers
Thanks guys, they are both pretty close. I'll print one off and take it out there with me. You can't read most of what mine says anymore. I'll take a meter and pop the other fuses out and check them too. They look ok but that doesn't always mean anything. The one I found was clearly popped.

Could be the Turn Signal Switch inside the steering column.

You didn't by chance change the bulbs out to LED's did you?

Re: No blinkers
Does the horn work? All the electrics for the turn signals work off the steering column wiring harness. Hot wire into column and signals out. If you don't have a horn then you don't have power coming in to the harness.
Signal wires are dark blue and light blue. Disconnect the horse shoe connector and test with a 12 v test light. Wiring diagram is your best friend. Even if the colors are different but the wire is ran correct it helps you find the mistakes.:chevy: http://www.jimbosprint.com/ChevyC20/...ruckWiring.jpg |
Re: No blinkers
Ok guys, I figured it out. much easier than we thought. This is an all brand new steering column and the hazard button was pushed in. I couldn't push it in and couldn't pull it out. So I searched on here and found that someone said it took a ton of force to pop out the hazard switch the first couple times. I went out and put some elbow grease into it and bingo! everything works. (except the hazards) but that's the relay I think. At least I can drive and not worry about a ticket for no turn signals. I appreciate all the helpful tips.

Re: No blinkers
If your lights didn't blink when the hazard switch was pushed in it means the switch is not getting power from the emergency flasher, which would explain why the turn signals didn't work when the hazard switch was in. Check the brown wire in the middle of the column connector for 12 volts constant power and if it has no voltage then the hazard flasher may be bad or the wiring connector may not be making contact on both sides. It is also possible that the TS switch hazard circuit is bad.
Start by swapping the two flashers and see if both flashers work the turn signals. If neither one works the hazards then it's a power issue at the column connector or the TS hazard switch. |
