One problem related to exterior lighting has been reported for the 1997 Ford Explorer. The most recently reported issues are listed below.
I own a Ford Explorer XLT 1997 and the rear passenger door on the drivers side only opens from the inside while the other rear passenger door will not open from the inside or out (child lock not activated). The drivers door doesn't lock and when it does lock, it doesn't unlock or sticks so bad it has be unlocked with pliers, causing the driver to have to get in and out of the car through the front passenger side door. The interior map light and rear interior door light above the backseats stay on constantly even when switched off and the lightbulbs had to be removed because they wouldn't turn off and were overheating.
