if you checked your bulbs and you are getting power and your switch in the steering colum is working and none of your signals are still working or brake lights. check a black ground wire behind the dash that needs to be grounded its on the driver side and hooks into a slot at the bottem of the dash near your floor lamp
check your bulbs
take the car to an auto electrition
. your question about the brake light. the brake light shown not light up went you press on the brake pedal. if it light up is went you have a brake problem. good look
Possible ground issue at the taillights.
replace the relay under the hood Also check brake lights switch had the same problem switched bulbs and worked fine
The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.
Check the bulb.
If the bulbs and fuses are fine, it must be your brake light switch attached to the arm on your brake pedal.
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.
I suspect either a faulty ground circuit, or a much easier fix, faulty bulb/bulbs. You might be surprised the havoc a grounded out bulb will cause an electrical system.
On a toyota tacoma 2003 SR5 when the tail lights are turned on the brake lights come on and when the tail lights are of the brake lights work just fine what could be the problem. If the truck has a trailer plug, inspect the plug and plug wiring for damage and corrosion.
This usually means a bad or wrong bulb in the tail lights
