On my 96 limited the controls are on the mirror for the auto matic lightsas well as the tinting mirror
My '98 lmtd. is similar. There should be a sliding switch on
bottom center of rear-view mirror, sliding it all the way to the
LEFT should de-activate the auto settings, returning control of
lights to light switch,(wherever yours happens to be).
1994 Ford Explorer Limited Edition: the automatic headlight control is on the plug in rearview mirror. Pushbutton off/on, turn that off; then you can turn headlights on and off as usual using the push/pull control found on the dash next to the driver's side door.
