The divers side headlight doesnt work on my wifes 97 explorer. Replaced the bulb and same thing no low beam but has high beam. Passengers side is fine. I remember soldering something on her onboard computer when none of her lights worked before but dont know where to check for this.

 

If theres no voltage at the headlight & interior fuse 8 is not blown, the most likely culprit is the lamps out warning module.

If thats the case you might be able to resolder a loose connector pin (pin 12 or 13)at the module

 

It was the lom AGAIN.
