short circuit somewhere, usually if you have towing lights plug at the rear end next to where the towball would bolt on they get crossed very easily
Check your fuses! -I once got a ticket for 'no taillights' when my dashlights were fine -it was the fuse.
If fuses check out fine, then check the dashlights and taillights themselves, if those check out then most likely there is an electrical problem elsewhere
I would first check all fuses. My 2002 uses a weird configuration and requires several fuses to work all of the lights properly.
A simple first step would be to check the fuses to these lights, then go from there.
Working brake lights are important for safety reasons while driving. It is important to check all of the wiring, if the brake lights are not working and the fuses and bulbs have been checked.
Check fuses, check for loose connections, check wiring,
If you're CERTAIN that the fuse is good, check the headlight switch. There is a separate circuit inside the switch that controls both the dashlights and tail lights. If the INPUT to that circuit is working but there is no power out from the switch, you'll have exactly the problem you duscuss.
check the fuse for the tail lights, usually they are inter-connected.
Check fuses
Have you checked the bulb? Put a test light across the terminals.
checkALL of your fuses short could be a problem. i have a 95 blazer, bumps may of screwed up wiring like in mine
You can check your fuses, but most likely the bulbs have just burnt out. This happens frequently.And for replacing them, refer to my other answer here:How_do_you_repair_the_dash_lights_on_a_1990_ford_escort
