My passenger side low beam headlight recently went off on me. ... I've changed the bulb again, and changed the fuse just in case, but .... My driver side headlight wire got loose so when i hit a bump at night if would flicker. ... When you notice one side not working (Low or High beam) it could be the module. Headlight replacement

There should be a left and right fuse and a relay involved.
The lights get power from the fuses, and the headlight switch and dimmer switch provide the ground circuit. So if you check the headlight plug with a meter you should have power and ground for high and low beam.

check low beam fuse when switched on if it has voltage registering across the fuse ,if there is voltage across the low beam RHS fuse then it is possibly a pinched wire from the headlight running back towards inside of the car

On these cars the headlights get power from a right and left fuse and the headlight / dimmer switches provide the ground circuit. Both headlights are connected to one ground wire for high and one for low beam. So if one works and the other does not, the problem should be in the wiring before the headlight switch. Red is for high beam and red-white is for low beam. You should be able to jumper the red-white wire on the right headlight and make the low beam circuit for both sides work to test it.

Check the headlighlt. The low beam filament may have burned out.

Look for a poor ground connection on the affected bulb socket.

is located under the dashboard on the driver's side. The fuse label is attached under the steering column. If something electrical in your vehicle stops working, check for a blown fuse first. Below table outlines detail fuse number, its ampere and circuits protected.

If your getting power at the headlight wire harness, then it's going to be the bulb it self, but make sure your checking the right 12 volt terminal at the plug. There should be three terminals there, there is a ground, 12 volt low beam, and a 12 volt high beam. If both the low and high 12 volts are getting power, then it's going to be the head light bulb it self that has reached the end of it's life time since the day time running lights are always on which is the high beams. Good luck and check the fuse box under the hood by the battery.
