If you have power to the trailer plug. Then check and if you have power to your bulbs. Remember to check your third brake light bulb also.

Brake lights went out so I changed a blown fuse,now the brake lights wont shut off,so I replaced the brake switch at the pedal and still have the same issue,lights wont go off.


Which fuse did you replace ? The one in the under hood fuse box or one of the two in the I/P fuse box . Do the CHMSL - center high mount stop lamps work correctly ? Here is a description how they work .
Stop Lamps
The STOP LP 25 A fuse in the underhood fuse block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to both the STOP 15 A fuse and the CHMSL 10 A fuse in the I/P fuse block, and to the turn signal/hazard module. The turn signal/hazard module then supplies voltage to both of the trailer rear turn/stop lamp supply voltage circuits. The voltage from the CHMSL 10 A fuse is to the center high mounted stop lamp (CHMSL) and the trailer jumper harness. The voltage from the STOP 15 A fuse is to the stop lamps, throttle actuator control (TAC) module, and the cruise control.
Does yours have trailer light hook up ? If so check trailer wiring connector for corrosion . Also check the turn signal / hazard module .

No trailer Brake Lights right or left side


Try the specified fuses in the under hood fuse center. they are common to blow.

No voltage going to the brake lights when the brake pedal is pushed.


Your brake lamp circuit is very simple. See the diagram below. The only thing between the fuse and the brake lights is the switch at the brake pedal.

98 silverado no brake lights


The first thing is to check for power at the brake light switch,there should be power to one wire the other wire power up when pedal is pushed, this will tell you if it a power loss if theres no power to switch, if theres power to switch and through switch with pedal pushed then loog at the connect for signal switch its near column big connector as brake light power goes through switch you may have fryed that wire have some watch lights as you wiggle but this is only if you have power at brake switch. if theres no power then double check fuses even in the engine compartment, mostlikly it a fuse the wiring should not of burnt with a fuse in line, theres fuses in engine fuse box that also control lights.

Trailer wiring


Have you checked the fuse box under the hood? There are seperate fuses for the truck lights and the trailer lights. If the fuses look good use a 12 volt test light to check for power on the turn signal pins when the brake is pushed. The brake lights and turn signals use the same wires to work. Power here would indicate the wiring and fuses on the truck is all good, meaning the trouble is on the trailer. Check the bulbs to be sure they are the correct ones, they should be dual element bulbs. Make sure you have a good ground on the trailer, usually the white wire in the 4 way plug is grounded to the trailer frame, do not depend on the trailer ball to be the ground, this is asking for trouble.

No brake lights


no theres a switch its just way up in the dash.check fuses if it has a trailer hitch chec to make sure the trailer plug splices or connectors are good.there are fuses under the hood also. check every fuse not just one that says brake light some fuses feed other fuses
are you sure the bulbs didnt burn out one at a time and you just noticed it because the last one burned out?

Ford f150 2002 has no brake lights


yes there is. Above the brake pedal there is a switch tat turns the lights on when you press the pedal. It is tough to replace due to the lack o room to put your hands. but is an inexpensive part.

Trailer brake controller problem


I found the problem. Talking with a technician from the controller company, we determined that it was a fuse problem. I found that the fuse to the CHMSL was blown.

2003 durango brake lights stopped working


Something is being missed,start with checking the fuse for the brake lights. Then check the brake light switch for power in and out(when depressed).Your ground is intact so no power. If still nothing, remove the lamp in question and test the contacts. good luck. Don't forget to depress brake pedal while probing contacts.
