How do you change the headlights on a 96 ford aerostar battery in the way and many other things blocking access?

There should be 2 or 3 screws holding the metal trim in place that hold the lights in place.

You maybe able to remove them that way not sure if there will be enough slack in the wiring or not to allow this. Good Luck and Remember.

Change Your Mind, Not Your Oil.

You can remove the headlight trim rim around the headlamp by removing the 2 torques screws next to the turn signal light and 2 near the grill. after removing the trim, there are 4 screws, 2 on top and 2 on bottom of the headlight lens. The headlamp assembly then removes easily and has a clip on the back that holds the bulb in.
