Brake Light will not work? Cab brake light does.

For starters it is spelled "Brake" light...LOL . Sounbds like you may have a brake light switch that has gone out. In yor owners manual does it show more than one fuse for the brake lights? Most vehicles with a thrid/highmount brake light split the brake light power to either the left and third brake light and the right brake light or vice versa, or posibble 3rd brake light on its own fuse. I would check if all of the brake light including the 3rd brake light dont work. If no lights work at all it leans toward the switch which controls all or them to activate hence the brake light switch. It should be mounted on your brake peal arm or to the main base. The pedal lever activate the switch when you depress the brake pedal.

If the center brake light works but not the others, and the bulbs are good, the problem is usually the turn signal switch.

The brake warning light is for the hydraulic system.
It could be low on fluid or several other things. There may also be a warning light for a dead brake or tail light.

The rear brake lamp is a whole module. Get the whole unit for left and right no after market one the pins are not always correct

Im having the same issue on my 04 Quad Cab Dakota. Changed out the brake light switch but still no brake lights. You have any luck ?

replace your stop light switch its on the brake pedal

you need to do basics first,
check to see if bulbs are good,then verify no voltage at bulbs,
check to see if your truck has has a tailor hitch and wiring installed.
where they connect to your original wire is where you need to check first,

white wire feeds both and it may be connection inside roof area behind light lens bracket.

CK THE BRAKE LIGHT SWITCH ON THE BRAKE PEDAL FOR POWER IN & OUT WHEN ON THE BRAKE.IF IT IS OK U MANY HAVE A PROBLEM WITH THE TURN SIGNAL SWITCH.POWER GOES THROUGH THE SWITHC TO THE REAR LIGHTS.WIGGLE THE TURN SIGNAL SWITCH WHILE STEPING ON THE BRAKE IF THEY LIGHT OP THE T/S SWITCH IS BAD.

after u check all the bulb try to check the fuses if its ok change the brake light switch which is located front of the brake pedal
