Headlight malfunction

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!

Hey All, So I finally had a chance to look at the headlight and bottom line it was a simple grounding issue. A.K.A. the low beam was shorting out and causing a ground short that then caused the piggy backed high beam to not work also (figured this out after about an hour of tracing wires and checking grounds). 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).
