Brake lights not working

There is a break light relay I think down under drivers side, or under the hood in the fuse box. Blinkers are working so the circuit is good.

Thanks Rowefast, it was the brake light relay. Replaced it and they work fine

I swiched my relays and still no change im having the exact same problem cab break light works but the ones on the bed dont everything else is fine any ideas?????

I have the same problem. The relay is good all other lights work, power through the fuse is good, new lamps. Any ideas other than trying to trace the signal under the dash from the relay box?

Helpppp having same exact problem. I've replaced brake switch brake lamp relay too. Still no brake lights but every other light working fine. I've even gone as far as tracing out wires with test light. I have no power after brake switch. I replaced it twice thinking I got a bad switch. I have 2 wires with power to the switch and only 1 post at relay with power. PLEASE PLEASE PLEASE HELP!!!!!!

Is my relay bad if passenger side break light is working all my problems are with the driver side replaced bulbs checked front lights and bulbs both new circuit boards and checked ground sometimes it works somtimes it don't and answers?

Brake lite works /when you turn off vehicle the power booster bleeds off and brake lite comes on and will drain battery?

30 amp Fuse under the Hood in the main fuse Panel if it is not the relay.

After a year of disappointments and sadness i had parked my favorite truck cuz my brakes lights quit working , i decided one day to completely strip.the front engine compartment wires and redo them.recheck every ground and main wire and right by the brake relay on the firewall i found a ground not connected right .i resoldered the connector and used a self taping screw to ground it ...and out the blue my brakes are working fine ..so its the ground from the relay folks trust me .i used half my head over the course of the year trying to figure it out ,i almost gave a perfect truck to pick and pull over it

I am having this issue now bulbs good switch was replaced, fuses are good, swapped relays around all seems to be good. The only brake light I have is the one on the cab!! Any help would be appreciated thanks Jason

I have the million dollar answer Guys

I rewired bought fuses , relays and 3 different brake switches the whole time it was the stupid azz white connector to the white wire it spices into the other white wire into the steering column take out the connector and connect them bare or however you want to connect it but I bet a dollar to a donut this fixes your problem
