Why dont you start by checking the fuses for headlights refer to your owners manual for the location of the fuse box for your car. if the fuses are good then replacing headlight bulbs to both headlight assembly is your next step.If after replacing both headlight bulb you still have the same problem then you might have other electrical issues.

check light socket for corrosion also for the CORRECT bulb

Junk the stupid van and get something else

Is the hrness and headlight getting a good ground ? I would try cleaning it where your ground hooks up with sandpaper.

to replace the headlights themselves, no. under the hood, find the headlight. where it connects to the headlight lamp, it should simply twist off and pull out. Then you must unclip the clip holding the light on. It sounds sort of confusing, but it's really easy! Let me know if you need a bit more clarification.

Either you have a short, or you have attatched the parking light socket to the headlight. Let me know please, this is an interesting one

He can give you driver's side directions also.

there should be a triangle shaped plastic section on the interior of the door behind the mirror, check it for a little plastic screw cover to remove it or you may just have to lever it gently to remove it.
once it is off it exposes the mirror retaining bolts which you undo to remove the mirror, I presume it has electric mirrors and if that is the case you will have to find the electrical wire plug for the mirror and pull it apart, replace mirror in reverse order of removing

Go to your local NAPA auto parts store and get replacement tail lights circuit boards. This should solve the problem. I did for my daughters van.
