turn signal/electrical issue
alright i posted this a while ago, some ideas were thrown on the table..
pleASE all advice will be considered
nothing was concluded.
heres what we know,
-Left turn signal Used to just stay on when i flipped the lever down
-changed the flasher relay in the dash.
-Now it flashes a trillion mph
-it only does it when the headlights are ON
-the hazards flash once and stay on
- changed the rear bulb because there was question.
what do you guys think?
some said multifunction was bad, but this sounds a little different... dont want to buy it unless you guys are pretty sure.

My left signal light recently started to flash "a trillion mph" also, but only when my steering wheel is tilted down. This was happening when I bought the truck a few years ago. The signal was replaced and the problem was gone. This may not be your case, but you might want to investigate this.

You have a short drawing more amps than the flasher can handle.
I've seen this a hundred times...
Same thing happens when adding a trailer tow package, but without upgrading to a heavy duty flasher...
I'd about guarantee the short is to the headlight circuit. I BETCHA it's at the front of the truck! Check your wire looms where they go through any sheet metal. Also pull all your lenses and bulbs and see if the bulb sockets have corrosion inside them. I'd try that first.
ONE LAST - if you have any collision damage on the front of the truck, take a hard look at all the wiring in the immediate vicinity of it.

yea this is what i was affraid of ,lol a needle in a haystack, first im going to check the trailer wiring make sure some thing didnt short, then i will head under the hood, i dont know if it ever had and front end damage, i dont think so, but i will investigate, i have a strange feeling it had a snowplow on it once (yes, on a 150...) there is alot of plastic cut under the front i put my bullbar on and the mounts on the frame were already exposed... so maybe the lighting was tapped on to or something, i will have a looksie...

All your headlight wires are up front.
That's what makes me think the trouble is up there - you said it only messes up with the heads on.
I bet a headlight is drawing from the wrong wire.
What bothers me though - is howcome the headlight SWITCH is involved? Has someone been up under your dash?
Do you see any added on wire up in there? I bet when this is figured out, you'll be trackin' a man down to tell him how stupid he was...

SOLVED!! my led strip light under the tailgate that plugs into my 4prong trailer end has a dead short apparently, i had a gut feeling about that... the ends looked rather corroded, i played with it and it worked one minute and not that next.. so i unpluged it and it works so we'll see if it lasts.. so glad it was something simplE all this bs!
