Your brake lights are on a live switch , they will go on when the key is off. so if they are on, your battery will eventually go dead.
now on the pedal there is a switch so when you push the brake the light is activated and so is the actual brake. Check and make sure it is still near the pedal top and can be activated with the pedal down .some are reverse switched down is not making contact and so is tripped and others is brake pedal arm is down toching the button depressing it and making contact. contact your local parts store see what parts they have for your make and model. DONT BUY anything. just see how you switch is suppose to work then you'll know how to test it. if your not sure even call them or any parts store and ask how to test them . they love to share information. which makes them even more valued. Your Cruise wont work because of your brake switch deal. it thinks that you on the brake. Good thing too. Going down the highway cruise on....tap brakes and cruise keeps right on going. that would be very bad. Nothing to do with the battery. just that its a casuality of the brake issue.

Why do brake lights stay on while diving and cruise control doesn't work?


If the brake light switch connected to the brake pedal has failed, the brake lights are stuck on which fools the cruise control into disengaging.

My signal lights and brake light along with the cruise control stopped working


Sounds like something happened to the multi-function switch or the wiring harness in the steering column.

How to fix cruise control


Cruise controls can cease to engage if the clutch or brake light cruise switch are out of adjustment. If this happens, try placing you foot under the clutch pedal (if equipped) and lift up on it (toward you) and hold it while engaging the cruise. If it now works, it will likely cut out when you remove your foot from under the pedal. Check the brake pedal in an identical fashion. Adjusting the switch at the pedals can often solve he problem. Some vehicles (Honda, Acura, Ford, to name a few) have a plastic insert that mounts in the pedal arm which presses against the switch. These can become brittle and fracture into pieces. My Acura has little pieces of blue plastic on the floorboard around the brake pedal one afternoon and I noticed the cruise didn't work. It was the pieces of the insert that had come to pieces preventing the cruise from coming on. I replaced the insert and no more problem with the cruise.

Brake lights and cruise control stopped working on 2004 chevy tahoe


I suggest to check your tail lights. sometimes if they go out, the cruise control will not work. Oh and also, what i did when this happened to me, I checked under the brake pedal and pushed and pulled the little button that activates the taillights and it worked again. It may have gotten stuck..
The brake light fuse may have popped..

ALSO: -- There seems to be a recall for this..
CERTAIN PICKUP TRUCKS MAY EXPERIENCE THE PERMANENT LOSS OF BRAKE LAMP FUNCTION OR BRAKE LAMPS THAT ARE ILLUMINATED AT ALL TIMES. THE CENTER HIGH-MOUNTED STOP LAMP (CHMSL) IS AFFECTED IN BOTH INSTANCES. ALSO, IF EQUIPPED, THE CRUISE CONTROL WILL BECOME INOPERATIVE. ANY TRAILER BRAKE LAMPS WHICH ARE CONNECTED TO THE VEHICLE'S BRAKE LAMP WIRING WILL MIMIC THE VEHICLE'S BRAKE LAMPS WHEN EITHER CONDITION OCCURS.

After being stuck in the snow the engine light stays on and the cruise control does not work. I have checked the vacuam hoses and none seems to be loose.


Same thing just happened to my Dodge Magnum, turns out it was a stuck brake switch. It was telling sending the message to my cruise control that I had no brakes. It was covered under warranty and was located on the top of the brake pedal inside the car. It was fixed in no time.

2000 windstsar sel cruise control stopped working


Check to see if your brake lights are staying on.
I thought my cruise control stopped working too, but realized that it would not work because the brake light control on the brake pedal was stuck.
I changed the $40 control and the cruise control works.

Have you recently had any brake work done? I had a 05' freestyle that did the same thing.. when you tap the brake the cruise kicks off right? so if your brake pedal is sticking or not returning fully to the up position, the cruise will immediately kick off like you applied the brake. Check to see if your brake lights are staying on when you release the brake. Let me know what happens, please and good luck.

Auto has 23K and cruse stopped working. checked


I had the same problem with my 2003 santa fe. Do you have any brake lights out in back? Weird as it is, as soon as I fixed a burned out brake bulb, my cruise worked again. The only relation I can think of is that tapping the breaks causes cruise to turn off - so maybe a broken brake/tail light passes a singal to cruise control from some reason???

The rear lights won't shut off when the car is shut off.


the lights you have on are probably the brake lights. you need to check the brake light switch. it is probably stuck in the on position and that would cause the cruise to not function properly because the cruise automatically shuts off when you press the brake pedal.
hope this helps!
