2002 dodge dakota all lights work and no brake light put new bulb in still no brake lights

That makes sense since the rear taillights and license plate lamps come from the same power source, which is different that the ones for the backup and brake lights. Here are two diagrams that show the electrical path for the lights from the battery/fusebox all the way to the lamps. Hope this helps!

poor wiring connection or the bulb holder has distorted and the bulb not seated correctly are a couple of causes to check out

I would check the fuses along with the bulbs remember to check the underhood fuse and cab fuse if nothings wrong its something to do with the wires to the lights hope this helps :)

replace bulb for brake light...it is burnt out

there is a switch above the brake pedal that turns the brake lights on when u depress the pedal, use a volt meter set to DC volts and check for voltage to the switch and out of it when the brake pedal is depressed, see p[icture of switch below

If the bulbs are good I would suspect the Brake light switch.

Brake Light Switch: Testing and Inspection
The brake lamp switch can be tested with an ohmmeter. The ohmmeter is used to check continuity between the pin terminals.
Switch Circuit Identification
- Terminals 1 and 2: brake lamp circuit
- Terminals 3 and 4: RWAL/ABS module and Powertrain Control Module (PCM) circuit
- Terminals 5 and 6: speed control circuit
Switch Continuity Test
NOTE: Disconnect switch harness before testing switch continuity.
With switch plunger extended, attach test leads to pins 1 and 2. Replace switch if meter indicates no continuity.
With switch plunger retracted, attach test leads to pins 3 and 4. Replace switch if meter indicates no continuity.
With switch plunger retracted, attach test leads to pins 5 and 6. Replace switch if meter indicates no continuity.

Crossed up live wires with ground on the trailer harness, check the truck fuses for the lights they might be blown.

when brake light is constantly on it normally means the rear brake light dont work (bulb blown) ABS normally means sensors pushed too far or teeth on abs cv axle could be damaged or bent. check that first.

at the brake pedal the is a switch, when you press the pedal moves away from it which turns the lights on

i had the same prob with my 2002 dodge ram and i was told that it was the fuse box which cost 700 to 800 bucks.Ifixed mine with a relay switch and about 6 feet of wire
. works like new
