Check the bulb.
AnswerIf this were my car, I would replace the brake light switch ( near the brake pedal ). This could be the problem and is about the cheapest thing to start with. Good luck.check the ground connection at the taillights a bad ground will cause this
with the park lights on both left and right side are lite. but when the brake is applied the right brake lights up and the left goes out(doesn't light up)
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.
check your parking light grounds,lights are trying to ground back thru the circut .common to lose ground in the light socket or even a shorted bulb. most part stores have replacement sockets
On mine, when the lights are off, the left brake light is faint but still works. When the lights are one, the running light is on (faint) but goes out when I hit the brakes. And the turn signal doesnt ever work. When Ive checked the light bulbs they burn out fast. I have been told that replacing the plastic bulb housing will fix this. But I have not tried it yet.
AnswerIndicator light on dash? Check fluid level in master cylinderMake sure parking brake is fully releasedCheck Brake fluid levelI have a 1996 Tacoma 2.7L and my brake indicator light on the dash is always on. So- here's how to check what's wrong... Start truck, release parking brake, if light is on, push the parking brake handle in/towards dash, if light goes off then you have a bad spring (like my truck does) or the like on the parking brake handle. That's all. Sometimes when I drive, I push it in/light goes off and then the handle works it's way out again and the light comes back on.
It's PROBABLY a faulty brake light switch, but there certainly may be other possibilities. I just can't think of them right now.
Assuming you mean the red " BRAKE " light in your dash is lit : That means that either your BRAKE FLUID LEVEL IS LOW in the brake master cylinder or your parking / emergency brake is engaged
The earth wire or metal track on the bulb carrier has gone. Its an easy repair and the carrier should just clip off the back of the light fitting.
Maybe is the fluid brake that is low level.
you need a new brake pressure differential switch
If the " BRAKE " warning light in your gauge panel is on , either your parking / emergency brake is on and if not , YOUR BRAKE FLUID LEVEL IS LOW in the brake master cylinder located in your engine compartment
