Question about Ford E-150

1 Answer

Adjust brake light switch

I have a problem with my brake lights in my 2007 E-150 van. I replaced the pedal switch after checking the light bulbs, everything works: turn signals, hazard lights, tail lights but not the brake lights. I thought may be there was no voltage at the switch but again there's power there... any suggestions?

The brake light wire leaves the brake switch and goes into the turn signal switch. They often share the same wire: the rear turn signals and the brake lights. When turning, that side is routed through the turn flasher, but you get a steady brake light on the other side.
So you have power to the brake switch. Pull apart the connector for the turn signal switch, and see if you have power in on the brake wire (with brake depressed of course) going into the turn switch. If you have power in, plug the connector together, and see if you can backprobe the connector with test light or voltmeter, looking for power out to the rear brake lights. If power in, but no power out, the turn switch is probably bad.

looking at your schematics and , you say tail lights don't work , you didn't mention if front parking lights and license plate lights are working , they all come from the same source , a black /yellow wire , a good clue if front work and rear don't , please advise .if fronts work then you have a open circuit somewhere between junction S118 (near breakout for left headlamp) and rear sockets.

SOURCE: check fuse replace brake light switch, and still

first check the fuse for the stop light circuit, if it's good, check your bulbs, it's possible they are all burned out! take one of them out, swap in a new one, and see if it lights. If not, get a wiring diagram and start checking for your powers and grounds. Take a look at the stop light switch on the brake pedal. If it's no good, there is a good chance that your cruise control may not work properly either. Good luck.

Can you just check to make sure the ignition key switch is not staying over to far and not backing off when you try to start it. I had a truck that did that and it messed up my turn signals until I brought the key switch back a little after starting it. Just a simple idea. Be kind with your rating for me. Raz

Replace my brake switch on my 2000 Dodge ram pick up and my brake lights still don't work


Brake switch must be adjusted such that it is depressed with pedal up and released as soon as pedal is slightly depressed.

Brake Lights don't work on the back of our 2003 Ford Windstar


Did you actually check the brake light switch for power in and out ?
There are two different fuses, one for each side. And the circuit includes the turn signal switch.
The third brake light bypasses the turn signals.

Brake lights dont work, changed the fuse its was ok, changed the switch on the pedal , still not lights. flashers work, turn signal work, but not the brake lights. where to look next


Hi, your van does not use the signal filaments for the brake lights. You must have a wiring issue. Check for power at the brake light switch. If you have power there, the wire is broke from the switch to the S304 junction. If there is no power to the switch, the wire is broken between the fuse box and the switch. Please let me know if you have more questions, and thanks for using FixYa.

I have a 1993 Mercury Villager and my van is turned off but my brake lights are on and will not shut off.


Look under the dash, on the brake pedal arm. There are one or two switches that activate brake lights and shift unlock. Check for loose mounting nut or a missing rubber nubber. Is the brake pedal coming all the way back up? Look on the floor for something not usually found there. These switches are adjustable and it may be as simple as adjusting them. Have a helper look for brake lights on and shift lever unlocked while you push and release the switches with your finger. Depress the brake pedal to get it out of the way. Remember to set the park brake first. Could just be a bad switch or loose connector. Check fuses and the bulbs.

Hello, i have a 1997 subaru outback sport wagon and the brake lights do not work. the running tailights work. where do i start if its not the bulbs?


Check fuses and then try the brake light switch on the pedal... it should look like below:

You can unplug the switch and close the circuit of the wiring harness with a little pigtail of scrap wire and if the brake lights then work it's the switch.

best wishes!

3.5s v6 2004 nissan quest. brake lights not working.Already check fuse. kish.


First, replace bulbs and then check brake light switch, which is located near the top of the brake pedal. Use a voltimeter or test light to verify that there's voltage at the switch connector. It's not bad idea to replace brake light switch. Also make sure the brake pedal is correctly adjusted.

Brake lights are staying on constentily except in park


Also check the light bulbs in the 3rd brake light. If they are out (burned out or removed) the brake lights will remain on. I found this out by trial and error. I replaced the brake switch, tested voltages also and everyone told me that the 3rd brake lights should have nothing to do with it. But the do, don't know how or why, ford dealer wanted to charge me $86 for diagnositcs and $70 for complete 3rd brake assembly. Went to Napa and got bulbs for $5.00 (5 bulbs) and everything works now. Also this causes the cruse control not to work.
