1988 toyota corolla sr-5

Your brake light switch is stuck. It is located under the dash, near the top of the brake pedal. Replace it with a new one.

IF YOU ARE SAYING THAT YOU HAVE REPLACED THE BRAKE SWITCH AND NOW THE BRAKE LIGHTS STAY ON THEN THE PROBLEM IS THAT YOU DID NOT SCREW THE BRAKE SWITCH IN FAR ENOUGH.IT HAS A BUTTON ON THE TIP OF THE SWITCH AND IF THAT BUTTON DOES NOT REST ON THE BRAKE PEDAL,YOUR BRAKE LIGHTS WILL STAY ON.WHEN YOU PUSH ON THE BRAKE PEDAL THE BUTTON POPS OUT OF THE SWITCH WHICH MAKES THE LIGHTS TURN ON.WHEN YOU RELEASE THE BRAKE PEDAL,IT GOES BACK UP AND PUSHES THE BUTTON BACK IN WHICH MAKES THE LIGHTS GO OFF.ALSO MAKE SURE THAT YOUR ELECTIRCAL PLUG IS CONNECTED SECURELY AND ALL THE WAY PLUGGED IN.I HOPE THIS INFO HELPS, TAKE CARE AND GOOD LUCK, MANNY

You probably have a stuck or misadjusted brake light switch. The brake light switch located under the dash next to the brake pedal lever.

Check you brake fluid, If its low when you go WOT the fluid will move away from the sensor and the light with come on and take a few seconds to reset

Usually when it is on, it is due to either low brake fluid, e-brake is not full disengaged, or abs pump or circuit is faulty.

The positive or hot return wire for the brake light switch is now grounding out,brake light switch is now faulty or a short in the wiring is present bring the car to an auto electrician for diagnosis

If you put your foot on the brake, the tail lights and parking lights will still come on. Possibly your brake is sticking. Check to see if it is and if it is put WD40 for a quick fix. See a tech for them to fix your brake alignment. Good Luck!
