hi guys!
im new to the forum, im from puerto rico, and i got a 2000 v6 mustang, recently i had an accident, this old guy on a 1971 chevy invaded my lane and rip my driver side fender apart, anyway i got my car from the shop finally, it looks like new again, i turn on the headlamps and everything is fine, then i put on the highbeam, (since i got take this really dark road to get to my house) and only the passanger side comes on, the drivers side go off, i put back the low beams, and verything is fine, i already change the bulbs and that was no the problem, also chek the manual and it says its only one fuse for the highbeams, so i guess its ok since one of the highbeams come on, any help is really apreaciated,

thanks a lot!

 

My first thought was the bulb but if you already changed it, thats obviously not the problem. Maybe there was damage to a connection (i.e. Harness or wires) you may want the shop who fixed the car to have a look at it. Thats a hard problem to diagnose without seeing the car.

Good luck and let us know if you find out what it is.
