Well guess what!!!!  Both bulbs were burned out.  Hard to believe.  But it only cost me $29 for the service guy to find it and replace the bulbs…price included 2 bulbs.  Thanks for help/advice.

Jim’s right, check for bulb continuity and presence of 12V at the bulb sockets, or better yet, check BOTH fuses first. There’s a 20A fuse in the Power Dist Box that is hot at all times. That feeds the multifunction switch (flash to pass and dimmer control) and the headlamp switch (on/off). That source then feeds the interior fuse panel where there’s another 20A fuse for the headlights. Unless you have "Lamp Out Warning" module it’s pretty much as straight shot to the headlights from there. So I’d check both 20A fuses since they are both single points of failure for both headlamps. Agree that the odds of both lamps failing at the same time is low. bt – Hide quoted text — Show quoted text – > Need some help w/ a headlight problem on my 1996 Explorer (80000 miles). > All at once both low beam headlights quit.  High beams comes on and work > fine.  I checked at the low beam fuse block and got 12 volts whenever I > switched them on while alternating the high/low beam switch.  So the > high/low switich seems to be OK.  All other lights work corectly. > a.  Hard to believe both bulbs went out at same time, but I will check. > b.  Fuses OK. > Anybody have any ideas???  If there may be a common relay or connector that > may be the problem, please be as specific as you can as to it’s > name/purpose, what it looks like, where it’s located and how I can check it.

Attack the problem logically – you will save yourself grief. Check the bulbs first and then go to the next step. — Jim Warman

Need some help w/ a headlight problem on my 1996 Explorer (80000 miles). All at once both low beam headlights quit.  High beams comes on and work fine.  I checked at the low beam fuse block and got 12 volts whenever I switched them on while alternating the high/low beam switch.  So the high/low switich seems to be OK.  All other lights work corectly. a.  Hard to believe both bulbs went out at same time, but I will check. b.  Fuses OK. Anybody have any ideas???  If there may be a common relay or connector that may be the problem, please be as specific as you can as to it’s name/purpose, what it looks like, where it’s located and how I can check it.
