Check bulbs
take it to a mechanic I dont wanna "break lights"
Check the light bulbs for the brake they may be burned out or there may be a bad fuse.
I am currently having the same problem you are having check the fuse to see if it is blown the blinkers and brake lights are on the same fuse my system has a short in it somewhere and is popping the fuses I am in the process of running new wires since the wonderful people at Chevy ran all the wires thru the frame and you can't access them
They dont work. The bulbs are the most problems. Fix it!
Check the 30 amp brake fuse (green) in the engine compartment fuse block.
For the PS2 version there is not any indicators (blinkers). I dont think there any on there other consoles ether, but there is a horn and headlights.
coroded battery posts, a fault in the wiring, a ground not connected, ennie meenie miney moe...
The right brake light does not work on 1999 Ford Windstar. Tail lights and blinking light works. Changed bulb more than once, changed the plug in where the bulb goes but it still does not work. The tag lights are not working either.
Tail lights in automobiles are in use for the simple reason that cars behind you can see you at a glance. A car without tail lights can easily be camouflaged, in the right environment. Tail lights ensure that this does not happen, especially when a car is braking. and so me nor any of my brothers in arms dont pull you over that is always a easy way to meet quota
the hazard switch has two sets of contacts. when hazards turned on, blinkers cannot work,even if hazards dont work.for blinkers to work, hazard sw must be in off position-this reconnects blinker circuits to work normally. BUT-the contacts in the hazard sw get dirty and wont reconnect the blinkers to work
replace your wiring hornace that may help, plus check fuse box!
If the fuses are good then it's probably the headlight switch. There is a setting that turns the dash lights off, check and make sure someone hasn't been turning your knob.
