What would cause...

[big jimmy 91]

The turn signals and brake lights to quit all of a sudden on a 91 chev 1/2 ton?
Is there a flasher unit or something that could fail?
All the fuses are good except for the signal fuse poping once in awhile?
Possibly a short in the wiring?
Any thoughts out there as to where to start trouble shooting?
Thanks in advance for any info.

Sounds like a short somewhere. Follow the wires and look for somewhere where they may go over a sharp peice of metal that may have cut away at the wires. I had to rewire my whole tailgate on my blazer because the 25 yr old wire was getting hard and cracking etc.

I am kind of thinking the same.

It's just that it is 18*F , lots of snow and windy today (sucks to have an outdoor shop)
Also there are no hazzard lights when I turn them on

I guess it's time to dress up and go get salt slush soaked under the truck soon LOL
Thanks

Well I know how that goes. I have an indoor shop but its not heated. When I went through my tailgate and whatnot, it was -30 C outside so it was cold enough in the shop. (I live in canada if you're wondering.... )

HA HA , I didnt even notice where you were from flat lander LOL

I've driven through the praries a few times , very wide open spaces
You must do some mud running out there?
I know that I would love to mud bog in some of the farm lands around here other than hay making time
Well I am just going to have to get at it when my friend is off work some time (it is allways their vehicles that are a puzzle to fix when they are not mech. inclined )

 

[RustBuket]

Yeah its pretty much only mud/snow that we have out here. But you have to watch out since its mostly all private land.

Sucks to be you guys right now...it's a balmy 70 F here. I am almost tempted to ditch the hardtop.

Anyways, it sounds like you need another flasher unit. Plugs into the fuse block. I'd grab the old one and bring it with you when you get a new one. Some are two prong, and some are three prong.

Shouldn't take more than a minute or two to replace.

I Had The Same Problem All Mine Was, Was A Bad Ground Wire In The Rear Of The Truck
fixed it no prblems since

If the fuse keeps blowing, i'd replace or at least inspect/clean/dielectric grease your trailer wiring harness.
