According to the book, you have sealed beams--one piece:
To Replace:

  • Remove the headlight bezel retaining screws. Remove the bezel. If necessary, disconnect the turn signal lamp wires.
  • Remove the retaining ring screws from one or both lights.
  • Remove the retaining rings.
  • Remove the light from the housing. Disconnect the wiring connector from the back of the light.
  • Push the wiring connector onto the prongs at the rear of the new light.
  • Place the new light in the headlight housing. Position it so the embossed number in the light lens is on the top.
  • Place the retaining ring over the light and install the retaining ring screws. Tighten them slightly.
  • Check the aim of the headlight and adjust it, if necessary.
  • Install the headlight bezel. Secure it with the retaining screws.
  • Connect the turn signal lamp wiring (if it was disconnected).

How do I change headlight bulbs on 1997 Mountaineer

This info might be in your owners manual? I use gloves to handle bulb, not bare fingers. Sometimes the oil from your skin can cause a hot spot on the bulb.

2000 mercury mountaineer one headlight works the other does not and its not the bulb

Not good!

Simple/ not so simple...

Need to put a multimeter on it and see if you're getting power at the bulb. If not, you'll need to replace the entire wire from where the two headlights join together to the bulb.

Only other possibility is that it really is the bulb, and you got a bad bulb to replace a bad bulb. Easiest check would be to pull the bulb from the other side (knowing it works), and put it in there to see if that fixes it (and also put the replacement bulb in the good side to ensure it's a good bulb, too).

I need to know where the fuse is for my dash lights, and the fuse number

Should be on the same circuit as the headlights/running light fuse but if fuse is good you may burned out bulb and that's a pain to replace. Got to take entire dash apart. Or a short. Had that before, bigger pain.
