Question about 1993 Mercury Grand Marquis

1 Answer

I want to know how to fix the brake on-off switch. I have no brake lights and I was told that also because of the broken on-off switch is why I have to turn the ecnition part way on without starting the car then put it in nutural, then start the car and to put it in drive. I can not shift my car into gear if I start it before doing what I just stated. Where can I get a diagram to fix it? Maude

Maude the switch is in between the brake pedal and the frame that holds it on. look up under the dash and push the pedal down. When you do you will see something that looks like a cigar cutter. You will have to remove a cotter pin and the rod that connects the pedal to the power break booster threw the firewall. Once you slide that bar off you need to push the back end (facing you) of the switch down as you slide it to the left and off. Make note of how it comes off. One side has a hole, the other side a horse shoe.

Brake lights don't come on, but top brake light does bulbs and fuse are fine

you can get the switch from the parts store and it bolts directly to the backside of the brake pedal less than $50 buck to do it your self. But i would check for broken or chaffed wires first

Brake light switch wires broken

Here is a picture of the brake light switch. Also at this point just buy a new connector and splice it on, much easier.

Automatic shifter will not get out of park or release key from ignition.

Could be one of two things, both are easy to fix.

1. Faulty brake light switch - are your brake lights working? If not, your brake light switch is broken, and needs to be replaced. It sits directly under the brake pedal, and has a two-pronged wire harness plugged into it. The reason it won't shift out of Park is because it wants the brake pedal pressed before shifting into gear. And if the brake light switch is broken, it doesn't "know" that you've pressed the brake pedal.

The brake light switch should look something like this:

2. If your steering wheel was turned when you parked the car, it's possible that that the steering interlock is binding up. Simple thing to try - press the brake, and turn the wheel slightly to one direction or the other (it'll probably only go one way), while turning the key. You'll feel it loosen up. This can also happen if you're parked on a hill or against a curb.

Good luck, and let us know how it turns out!

Outside brake light stays on

check your brake light switch under the dash. pull up on the brake pedal, does the light go off? a return spring may be broken, however, more likely the switch. you can pull the brake light fuse to save your battery

2003 ford focus replaced brake switch lights will work in park but when i engage revs neut drive brake lights stay ?????

I have the same problem with my 03 Focus hatchback! Someone stoppedme yesterday to tell me that they looked like they were always on when i was driving but when i was in "Park" they worked... This particular driver was also driving a focus hatchback and asked me if my Cruise Control was working.. It actually was not and he told me the same thing happened with his focus. He said it was a wire attached to the back brake lights that had broken. I have not yet gotten it fixed. has anyone else had this problem?

Car brake lights won t turn off when car is shut down 1996 Honda Odyssey

It should be your brake light switch. There is a little plate welded to the arm of the pedal that has a hole with a rubber stopper. The rubber stopper is most likely missing, or damaged. You should be able to take a flashlight and see the plate and the switch. If the hole is plugged up, you will need the brake light switch, if not, replace the plug.
