If the bulb is in fact a working bulb, and the passenger side works, then I would assume the problem lies within the driver side socket. This is possibly due to corrosion or something similar restricting the contact between bulb and socket.
You have a broken wire.
If that is the same as the charcoal canister it is in the engine compartment behind the drivers side headlight
If this is your right headlight and both foglights that are out ,and your Ford Explorer is 1995 to 2001 ( 4 door model ) check fuse # 8 , 10 amp fuse in the fuse panel in the drivers end of the dash ( the removable fuse panel cover is visible with the drivers door open ) It's probably the same on the 2 door model
With lots of newer cars, only the bulb is replaced as opposed to the whole headlight assembly. Check and see if you can twist off the bulb from the backside of the headlight. Or, just go to any auto parts store and give them your car's make and year. When they find the product, simply ask them how it is replaced.
It could be a bad headlight bulb , or fuse # 4 is a 10 amp fuse for the drivers side low beam portion of the headlight
underneath the Explorer , on the drivers side , below the drivers door , mounted on the frame rail
