driver's side parking light/side marker out

Hi guys,
I've searched, and seen this problem, but no real solutions. I cleaned the ground behind the driver's headlight, and still not working. Headlights work, taillights work, just the driver's parking/marker lights. Checked the bulbs. Besides the ground, what's the next place to check? Really need a wiring diagram, but it baffles me why one side would go out, and not the other.

Thanks!

The side marker/turn signal light in the fender flare does not have a direct ground, but is grounded through the opposite lead being used and back through the parking/turn signal light on the front. If your light bulbs and grounds are confirmed good, I would check the front socket for corrosion or a broken wire. You might want to try a jumper wire from the base of the front socket to ground.

Thanks. BOTH the fender flare light and the front parking/turn signal light are out. Sockets look OK. Where is the front parking/turn signal light grounded to?

Open the hood, and look right in front of the horn on the inner grill panel.

Yeah, that's the one I already took off and cleaned. Any sense in doing the same on the inner grill panel, passenger side (if the passenger side lights are all working ok)?

They are grounded individually, one to each side. You might want to take a test light probe and see if you have power in the wires, but if both turns and parking lights are out in both lamps on that side, it kind of points to an issue on the ground side unless someone has forced a lamp in 180° off, or there is a bad socket connection...or bad bulbs.

Pretty sure I checked the bulbs first.

I agree, there is no voltage at the side, turn, or fog light sockets. Doubt all three sockets went bad. I don't have a wiring diagram, so I'm wondering if anyone does, or has knowledge enough of the circuit to help me diagnose. I checked the ground behind the driver's headlight, cleaned it, but that's as far as I went, and no dice there.


Thanks

If parking and turn signals are both out and the lamps are good, it pretty much either has to be a ground (check the end that grounds to the light fixture plug) or maybe a common connector that is pulled partially apart. What year is your Jeep?

You can view a wiring diagram here: Jeep Knowledge Base just click on the select button, and after you get to your year, if you scroll down to the wiring, you'll find it all broken down into sub categories.

There should be a connector (several) on the inside left foot panel where all three of those circuits pass through...maybe one is unplugged.
