Is your car acting strange, but you just can’t figure out why? Typically these wired electrical gremlins are caused by faulty grounds. In this video, I’ll show you how to find those gremlins and cure the issue. So hopefully you’ll take the next ten minutes to learn something from this old man.

I was tearing my hair out until I watched this. Thank you!!
Had a front flasher issue on my 2010 Wrangler Sport. Was able to fix it after watching Mark’s video and repairing the corroded ground. Thanks!

Glad it helped
I have similar problems, also on the drivers side rear. I'm gonna try this tomorrow.

Good deal. Hope it helps!
Just wanted to say thanks I went right to that bad ground and that seems to be what the issue was and appears to be fixed as a direct result of your advice
I have a similar issue with my Jeep. The lights will flicker and go out intermittently then come back on. I'm going to check my ground connection as well
A pre-emptive like on this.
cool thanks!
Nice video! Have you had to diagnose a JKU PCM or do you know at what location it is grounded?

No, I have not. There are a few grounds located near the PCM. I would guess the engineers would use one close-by, so I would start by cleaning those.

Any luck? I’m dealing with the same issue
Do you have any knowledge on where the alternator grounds? Tia
Basically all the grounds all the way around the engine bay need to be cleaned, cut back, soldered & re terminated. Jeeps have horrible wiring that easily corrodes.

Yep. The engine ground stinks too. Been fighting with O2 sensor grounds too.
I’m having an issue where the marker light turns on but the turn signal does not flash.

Sounds more like a bulb issue than a ground. The easiest way to check is with a good bulb. Pull the other side, test it in the bad side.
