Hi,

 

Well I got my new truck the only problem I encontered after a 1600km drive is that the left turn signal doesn't blink with headlights on... Any ideas ?

I know the headlight circuit has no tie to the turn signals. Headlight ground is in the driver side kick panel and the turn signal ground is on the driver side fender near the headlight.

Does it blink for sure with the headlights off? Just a double check.

Yes it does blink with the lights off I checked.  With the lights on the blinker light turns on but does not blink.

Now what I did find the flasher module does have a separate ground and fuse. The flasher ground is the G201 right center dash support. The fuse 10 in the cab fuse panel.

Would you happen to have a diagram that shows the location of those grounds ?, I also tired putting the 4 way flashers with the lights on this morning and they all blink very fainthley...

Thanks, so for that ground if I take off the front of the dash or bezel I should be able access it ?

Unknown... You might have to poke around a bit I know its there some where.

Got it running it was a bad ground after all. I just added a t-tap wire splice to the ground wire of the left turn signal and grounded that to the body.

 Always good to see them fixed, no matter the problem.
