Hey everybody
been here a long time following but never posted. I have a Wj (2004) that seems to be having electrical issues with the head lamps. The problem is that the drivers side works fine the the passenger side will not. The passenger side low beam will barely glow and when te high beam is turned on I have nothing. Also turn signal will not work either but in the car on the information center it will tell me it is on. All bulbs are good and I checks grounds which seam to be good,I'm at a loss and any help would be appreciated. Also mind you guys mechanical work I can do but electrical I've never gotten the hang of so thanks for the help

How did you check the grounds? You can't just look at them. Take them apart, clean them up, and check the wring. An ohmmeter from the headlight socket to the ground terminal, with the terminal disconnected, will tell you about the condition of the wire and the connector.

I pulled all the grounds apart and cleaned them on both fenders of the jeep.az I stated I'm not great with electrical so I am unsure of the resistances of the wire. I checked contanuity and all that checks out. I have figure grounds because when I checked voltage at the bulb I didn't have 12 volts but when I put the ground to the battery and left the positive at the plug I had 12 volts. Just not sure of what are grounds or how many there are at the plug. I haven't been able to get a manual yet due to money issues and couldn't find a whole lot on Google.

See my sig, #1. There is a link there to photos of all the ground locations.

I haven't had this with my WJ, but did with an older Benz. One headlight was dim, even after replacement. I had continuity in all terminals, but the light connector didn't quite look right. Replacing both headlight connectors solved my issue. There's a lot of amperage going through those old school lamps, and those things need to be a full capacity. Don't know if it'll help you, but it's a good place to start.
