When I turn on my headlights my turn signal indicators both come on also...? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well... When I turn on my headlights both of my green turn signal indicators also turn on. Also when I flip on either turn signal they do not work. With the headlight off everything works fine... Any ideas? It sounds like I have some wires crossed somewhere...

Check your fuses.

It might not be wires crossed, it might be a bad ground connection in your headlight circuit. Just enough to allow low power from your blinkers to work, but the high power from the headlights causes problems.

The analogy would be a slow sink drain. A slow trickle will go down the drain fine, but as soon as you turn your faucet on full blast, it backs up and starts leaking water into other areas.

I would guess that you have a bad ground.

It means you have a bulb out on the side the signal is pointing

Hazieview · 10-18-2017, 06:32 PM

That makes since fellas I appreciate it! Hopefully I can find a ground wire unhooked somewhere.

All bulbs are working.

One more stupid question... Do the parking lights (the ones behind the grille) flash along with the front side markers? It's been so long since I had my truck inspected that I honestly can't remember. Lol

Mine parking lights don't flash... If they are suppose to then maybe I have the wrong bulbs...

Yes they are supposed to flash

If you put in LED bulbs it can do that.

This is correct, LED bulbs can make all kinds of weird things happen.

My turn signal indicators are actually LED bulbs. Perhaps that is my problem...?

I ended up changing out my Flasher with a 'LOUD' LF12 Novita Turn Signal Flasher from Autozone. I also found a broken ground wire on the passenger side running light (behind the grille). Thank you guys for all your help. Hoping to get my inspection tomorrow!

Whenever I ask for a "loud" flasher the parts guys give me a dumb look. I am going to try that one. thanks.
