I just finished a front end conversion and both my turn signal indicators light up when I turn my headlights on. The dash lights blink when I use the turn signals and the exterior lights all work like they are intended. I have checked my ground wires on the radiator support and they seem to be tight. The turn signal dash lights are fine until I turn the headlights on then both indicators light up. I think is has to be a ground but does anyone have any ideas?

Thanks

 

Well I found that if I run a new ground to each turn signal, the dash indicators don't light up any longer. I also found that after a couple miles you also have smoke from a bunch of wires burning under your dash. On a positive note, my gas mileage went up with the help of the tow truck! This is why I need a new hobby ha ha, still waiting to hear what the damage is going to cost me.

 

Well I got my Blazer back, and it turns out that both front turn signal bulbs had filaments that were shorted together which caused my indicators on the dash to stay on. The turn signals were working though. The wiring that went up in smoke was an after market remote keyless entry that was tied into the light circuit. So if your dash lights stay on and your lights outside are still working, check your bulbs.

 

one question did the turnsignal bulbs still work even though the filaments were shorted together and by turn signal bulbs do you mean the ones below the headlights or the side markers right beside the headlights
