Default Headlight malfunction

Hello, Im not sure if this was discussed yet or not (I didn't see anything when I searched).. I have a 2009 Dodge Ram 1500 and I have been having problems with my passenger side headlight. I have the quad beam light assembly and for some reason the low beam and high beam do not work from time to time. The bulbs are still good and the parking light still works, its just the low and high beam. Just wondering if anyone else has the same problem or knows a fix? I didn't see any technical service bulletins or recalls on it yet and no one else seems to have anything online from what I've seen so far so I'm at a bit of a loss.

Thanks for any information!

I changed the bulb and so far so good. If it keeps acting up I will let y'all know. Thanks for the advice!

Have you taken the headlamp out to examine the wiring harness? The high/low beams are daisy-chained on the harness (or connected together in some fashion) so I could see how they might both be affected if something wasn't plugged together tightly or there was some other issue (water in the connection, damaged wire).

sounds like a ground not working correnctly - unplug any connections you can see, clean, paint a little dielectric grease on there, and put 'em back together

@Firebug I'm having the same issue and I would appreciate any info on how you were able to fix this problem seeing how I'm having the exact same issue.

Does anyone know if firebug still has a ram? He hasn't logged on for a few months and I'm having this exact same issue and I was wondering what he did to resolve it.

I just started having the same issue this week. I'm going to go get another bulb to have on stand-by, but sounds like I need to pull it all apart and see what the deal is. Hopefully a quick fix, but I'll report back on what I can figure out as well.

@ Matts I think if you have the quad headlight setup and both the low and the high beams are out I think you have more than a bulb issue. Reason being on the quad headlights the low and high are on two separate bulbs. But if you are able to fix the issue I'm all ears.

Thanks
