Drivers Headlight Goes On and Off Randomly

I am having a problem with my drivers side headlight randomly going off and on. The passenger side headlight works fine all the time. It typically happens more when I turn my headlights on, sometimes it comes on and sometimes it doesn't. If I turn my lights off and back on once or twice it will come on or if I start driving it will eventually come on. It sometimes goes off while I am driving but not very often but will come back on within a few minutes.

It acts like a bad relay but with me having an 09 Ram, it uses the TIPM to control everything. Are there any relay's in this system? Any other ideas?

Next time the light goes out, try getting out of your car and hitting the light a few times with your hand. If it comes on from movement, it could be a bad wiring harness or connector. Had this problem with my 11 Ram on the passenger side. It was actually a common problem as I saw threads on this issue also. I ended up cutting the wires and removing the harness and splicing the wires together. Never had a problem again. Hope this helps.

There are videos on youtube that show you how to take the headlight out if you need help. Originally I checked the headlight connector, unplugged and plugged it again. Looked fine, but after a few months the problem started again. The second time I just cut out the connector and hooked up the wiring without it.
