Slow turn signals
« on: August 30, 2014, 07:40:16 AM »
Hey guys,
I've got a 78 c15 fleet side and the tour signals flash very slowly. Occasionally not at all. Is this a relay issue? Not too much electrical experience so all help is appreciated!

This is a guess but first place I would check would be the flasher. See if you have another you can swap it with

Are you talking about the flasher relay? A little $4 part?

As long as all of the turn signal bulbs illuminate, I agree with Irish.

Your truck has two flashers that are completely interchangeable (two styles are pictured).  The hazard or 4-way flasher plugs into the top left corner of the fuse box.  The turn signal flasher plugs into a free hanging socket that dangles out of the wiring harness near the fuse box.  Swap the two flashers to see what happens. 

If you need to replace the flasher and foresee towing a trailer, replace both flashers with the electronic version.

Hey guys, little update on my flashers. I replaced the dangling relay and the interior indicators are on and click, but none of the exterior bulbs flash.

Ideas? Thanks everyone!

Did you get the tin one or the plastic electric one? Do they flash fast or regular speed on the inside?

The tin one should flash fast if you have a bulb not working . the electric one should flash the normal speed no matter what. So the flasher is getting resistance some where

Any reason why none of the lights would flash?

Do the hazard flashers work?  How about the brake lights?  Have you checked the bulbs?

The brake lights work.... Unfortunately my truck didn't come with the hazard flasher knob on the column so I don't know if that would work
