Wiring issue or bad relay ?

I have no clue if it’s a bad wiring harness or a bad relay. When I have my headlights on or my corner lights, my left turn signal light stays on and does not flash. But if they are off it works like a turn signal. If I try to use left turn signal when headlights are on it barely blinks and also makes both corner lights blink. Anyone ever experienced this ?

 

Do you have a towing wire harness?

 

Yes but this just recently started 3 days ago I’ve had everything like it is for almost 2 years as in lights

 

Sounds like a grounding issue to me.

 

Check and clean grounds under driver side kick panel and tow harness connections under taillight lens.

 

Have you replaced front/ rear bulbs with LED's?

 

I will try those and give y’all an update

 

Does this happen with the marker/tail light position also?
The first notch on the headlight switch BEFORE the headlights come on?

 

Yes this happens anytime I turn the corners, or the heads

 

Yes but I got the led compatible flasher so I don’t have hyper flash

 

If it were the flasher it should do it with BOTH turn signals.
There really isn’t a “separate” circuit out of the flasher.
The circuit is diverted through the Turn signal switch.

I’d pull the Tail fuse, then see what happens.
You can’t run it this way, as you’ll need tail lights.
But that should help narrow down the search.

 

I have aftermarket tails and only led turn signal is front and it’s not the flashing that’s the problem it’s when my headlights are on or my running lights the left turn signal is on and is not blinking but if I turn my passenger turn signal on that works fine just not my driver turn signal

 

Yes,

Are both the front and rear left turn signals coming on?
Or just the front?

I really doesn’t matter, as the turn signal bulb should not be powered by the headlight/tail lights.
You have power being supplied to the left turn signal when the tail lights are turned on.
Pull the tail light fuse out, then see if it the turn signals work correctly.
If so, you need to be looking at the tail light wiring.

 

The front and rear left turn signals are on/not flashing. As I pull the tail light fuse they work perfectly fine but the corner lights aren’t on when the fuse is pulled.

I don’t have switchbacks

 

It’s about led tail lights and voltage to the rest of the circuit - misread and thought I saw you had led reverse, rear turn signal or tail lights.

Have you replaced the your turn signals with the originals and gone back to the original flasher we relay to see what might be the problem?

 

It’s just the front turn signals that are led not back

 

Right. Have you replaced the led’s with the oem / stock parts to verify it’s not any parts you added causing the issue?

 

Yes I have and it still comes on with the original halogen bulb
