Check for a good connection and try adjusting the brake light switch on top of the brake pedal. If that doesn't work, replace the switch.

Check the brake pedal switch and the wiring. You may have a broken wire.

Replacing the Brake Light Switch - General

Answer
does the turn signals flash ?yes then the bulbs are good.
you may have a bad switch at the brake peddle. check to make sure the switch is moving out when you hit the brake.


More than likely it is your brake light switch out of adjustment. it is located under the dash on the brake pedal itself it is not breaking connection which it should be simple and you can fix it yourself and save yourself some money.


It's usually the brake pedal is sticking or you might just need to adjust the pin when you apply your brakes it makes those lights stays on. sometimes you can spray a wd-40 and it'll go away.. this pin is located on top of the brake pedal when you look underneath the steering wheel column or panel....hoped i helped you on this one...
The brake light switch may be either stuck or broken.

Get down in the driver's footwell, and follow the brake pedal arm up under the dash. Look for the switch (see link for a picture), see if the moving arm on it moves freely as the pedal is depressed. If not, try spraying some lube on it (WD-40 or the like) and working it to get it to move freely.

If the arm won't move freely, or the lights don't turn on even when you move the arm, the switch should be removed and replaced.
If you mean the switch that turns brake lights on when you push brake pedal it is above the brake pedal. It has a pin that pops out to turn lights on when you push the pedal and goes back in when you release pedal. It is pretty easy and cheap to replace.

That defect was recalled by Ford.see your dealer
Sounds like a defecive stop light switch-- switch button must be depressed to open (shut off) circuit
if both brake lights quit, you most likely need a new brake light switch that is located on the brake pedal under the dash
look at your brake light switch make sure its not burnt.(it's located on your brake pedal) You might also try a simple solution that seems unrelated, but often is exactly the problem (especially on Ford vehicles)...spray some WD40 into the hazard light switch, then wiggle/turn on and off/generally maneuver the button. It could be that your hazard switch isn't fully disengaging, which can prevent your brake lights and turn signals from behaving properly. It's good maintenance even if this isn't the problem.
Try replacing the brake light switch. It should be above the brake pedal.
The brake light switch has either failed or has become out of adjustment. The switch is often attached to the brake pedal mechanism, under the dashboard, but some are connected to the hydraulic pressure line of the brakes. Either way, it should be a relatively simple repair job once you find the brake light switch. That switch is also used to cancel the cruise control.
Check:

* bulbs

* brake switch mounted on the brake pedal
Follow the stem of the pedal up to where it connects up under the dash board. when you press on the pedal with your hand, you'll see a switch let out. There is two switches if you have cruise control. It's a 25 cent switch that ford probably charges five bucks for. It may be hanging up from dirt getting on it from a muddy shoe. All the switches in my 1998 are pretty cheap and hang up often. Spray a little WD40 on it while pushing down on the pedal with your hand. Then push the pedal with your foot and see if it works. Also, check to make sure mounting bracket not out of line from getting hit by foot. If it is, kick it with the other foot.... Watch that little floor light bulb, it gets hot, and smarts when it touches back of forarm. Also, keep WD 40 from getting on bulb. May get stinky when bulb heats up, and it somewhat flammible, but mostly needs a open flame before it lights. Good for frying Spiders in the garage, ants don't like it much either.
