Exclamation need help with headlights!!!!!!!!!

last night i was on my way home when my lights started going off and on. sometimes i had to switch to highlights so my low beams would come back on. also sometimes my lights won't turn on unless i flick the highs on and off.

pull the switch, those have a tendency to crack and arch causing this common problem.. if it looks good, check all your grounds and wires make sure they arent corroded

you are having the infamous fox body wiring problems...

better open up your dash and start replacing the wiring before you car goes POOF in a cloud of smoke and flames

if you had ur fog lights on at the same time, it will cause that problem ur having. i think u have to replace the wiring going to the light switch. i think some company sells the light switch w/ the upgraded wiring
