2014 JKU Headlights, Wipers & Blinkers: Possessed
I know, I know - it's my first post and I'm already asking for something. Please forgive me. I've searched the forums and found similar issues, but nothing that really describes my problem exactly. I'm hoping that someone here can help me out with this. . .
The Problem & My Rationale
My headlights are turning off and on by themselves. This is also occurring with my wipers and blinkers. It all happens at the same time - most of the time, it's only my headlights that freak out, while other times it's the headlights together with the wipers and blinkers. When it happens, my interior panel lights dim and return to normal.
It happens sporadically - even when I'm just sitting in the driveway with the motor running. I have noticed that it occurs more frequently when I'm driving, however. Interestingly, I've also noticed that it happens in the same places on the road that I'm driving on to get to my house, even when I'm driving very slowly. I feel the urge to say that it happens when I hit bumps, but that's simply not true. I've gone over bumps without it happening, and on flat pavement with it happening. There's just no difference where I am, how fast I'm driving, or how rough or smooth the road is.
I'm a satellite tech, and this kind of a problem screams "loose or dirty connection". How I would love to know where on the wiring harness I could find a connector that just happens to connect the headlights, wipers and blinkers.
What I've Done So Far
The first place I went to was the TIPM - I've blown out the connections underneath it with compressed air, and used dielectric grease to ensure a good connection. I've even disassembled the TIPM itself, and blew air under the circuit board relays. No dice.
I've tightened grounding points - two on the driver side kick wall, two on the passenger side, the one behind the passenger side headlight, the one next to the TIPM, and two on the driver side of the engine compartment. If this sounds like I missed one somewhere, please let me know - those are the only ones I could find.
I've checked the connection to the battery, and even replaced the terminal connectors. Next to the battery is some kind of a connector in the wiring harness; I've blown it out and put in some dielectric grease as well. The same for the connector under the heat shield (can you sense the desperation?).
Behind the passenger side headlight, there are several wiring harness connectors - all of which I've blown out and put in dielectric grease. On a side note, these problems began after I replaced a burnt out headlight on the passenger side, so to me, this was the most interesting place to investigate the problem, but alas, no dice. Everything is good to go there, short of pulling out the entire harness and doing continuity checks with a multi-meter.
I'm at a loss here, guys. Unless one of you has some insight already to this, my next move is to pull the dash out, and look back in there. God how I miss my YJ sometimes.
