faulty switch
WHAT ARE YOU DUMB REPALCE YOUR LIGHT BULBS STUPID! Not stupid replaced circuit boards checked fuses ran test light . When headlights are on no brake light or taillights and have all new bulbs stupid. Turn headlights off brake lights work, so figure that out smart man
All fuses are under the hood. The computer on the fuse box runs the headlights without fuses. It is all done internally. If you bulbs are ok, you need to have the FCM checked for codes.
have you checked the bulbs and fuses
Have you checked the fuses?
Have you checked to see if the brights are not just burnt out? Rarely do they both go at the same time, but it is possible.
Check the fuses and the bulbs.
Bulbs? Fuses? Relay? Dimmer switch? Headlight switch?
