You have a bad ground. Find the ground wire on the brake light socket. Run a jumper wire from a good ground to that wire. Try the brake lights. If they work normally you will need to trace the ground wire to its source and repair it. It could be a corroded connector in the harness, a corroded socket, or a corroded wire. Either way It is a ground issue. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

    well no luck finding problem. ..ran ground wire from light socket.. and nothing changed..put test light on trailer plug on back of truck and it blinked on both sides and the electric brake wire blinked as well.. dont know where to turn now.. i looked through the whole harness from front to back and found no burnt or stripped wires..

    Since it only does it on one side why not switch the sockets from one side to the other. If the problem follows the socket than the socket is bad. I'm pretty sure the sockets plus into the harnesses.

    I tried the socket swap and it didnt change any thing.i checked and removed the ground wires and cleaned and ground the frame to bare metal and nothing changed. i just dont know.

    sounds like you have tried everything you can. Its probably time to have an expert take a look. I'm pretty confident there is an easy solution just hard to say without being there.

    the other thought I had is does this have a factory trailer wiring or is it aftermarket. If its after market try unplugging/removing the aftermarket trailer harness.

It sounds like the shifter lock out solenoid has gone bad.It is a solenoid that releases the shifter when you push the brake pedal.

SOURCE: Third brake light flashing when engine is off, no main brake lights

this does not sound like a fuse problem. seems like a wiring issue. You probably have wires shorted together, and/or shorts to ground somewhere.

Brake switch is a good place to start, make sure it's working fine. To find the wiring issue you will need electrical diagrams, so get yourself a repair manual for a 1998 Explorer.

Look at connectors, see if you can find components or connections where all the brake light and tail lights connect to together. Using a multi meter you should be able to pin point the issue if u follow the wiring from the battery to the lights using the diagrams and checking connectors.

SOURCE: jumps forward when brakes are applied at intersections when stopping Doesn't happen all the time.

I don't know if this would be considered a solution or not but in 2006 Ford implemented a new transmission (6 speed automatic) and they have and still have a lot of problems. It is fixed (helped may be more appropriate) by a computer upgrade done by the dealership. MY wife has had nothing but problems out of her 2006 limited ford explorer. The whole computer system had to be replaced at 32,000 miles and then they charged us to upgrade the new computer they put into the car. It's almost comical at this point. The transmission problem has been solved for the most part on our vehichle but it took several ford computer updates. I hope this helps!

SOURCE: 1982 ford stepside. no brake lights. tried putting

Check the brake switch on the back of the brake pedal up behind the dash it should have to wires going to it and will be about 2 1/2 inchs long and threaded. one end will hit the brake pedal on the back side it will look like this >L where the arrow points you will see the switch it will have a quick disconnect on the back of it, and if you take a paper clip and install on the back side intot he wire harness quick disconnet swith look to see if the brake lights are on. If they are on then the switch is bad. to replace it has a half inch lock nut you can back off 1/4 turn then unscrew it out any parts store will carry it. It lists for 14.95 it could be the turn signal switch too. Now this is assuming you checked the fuses also this has two buttons on it and it may be the plug is loose. here is the web page the brake switch is at the bottom and the turn signal switch is about midway. This has a picture with it and price as well. Thanks for using fix-ya http://www.jcwhitney.com/switches/c1643j1s17.jcwx

Third brake light stays on; brakelights very dim; radio, clock, flasher emblem on dash blink when turn signals are used; signals flash fast when brake pedal is applied.


Sounds like you have a short somewhere in the brake circuit. May be between the brakes and the blinkers in the brake lights.

Sounds like a bad ground connection, probably in the back. You'll need to find the bad connection. Or if you can figure out which wire is the ground wire, connect it via a new ground wire to the body.

I can't look up your wiring diagram because I don't know model year?
On some makes and models, the lower brake lites are wired through the multifunction switch. Your turn and stop use the same bulb filament, just not at the same time. On a left turn, the left turn signal works, but the brake lite on the left doesn't. Now, the brake lamp on the right does work. The high mount brake lite also will work. The highmount brake lite is usually wired differently than the lower brake lites.
W/o being able to look at wiring diagram, I don't know if my info is applicable on your vehicle? I need model year.
