2001 Dodge Ram Van. The brake lights stopped working.

check fuses, there's a switch behind brake pedal under dash check it

do the signals lights work at the back if so then it sounds like you have a bad brake light switch or its out of adjustment. the brake lights and the signal lights work the same bulbs but are controlled by different circuits. the switch is located under the dash at the base of the steering colume were the brake pedal pushes against the switch.

I suggest first check FLASHER unit. On 2001 Dodge Truck RAM 1500 1/2 ton 4WD 5.2L SFI 8cyl the Flasher is located on seating area, driver side, at the left side ofinstrument panel on fuse block.

Hope this helps (remember to rating this free answer and leave a testimonial comment).

obviously first check the bulbs. If they are fine, check that a brake light connector is not diconnected. I have seen it once. The connector was used to power an accesory on the rear instead. Also, the connector or bulb sockets could be rusted or loosly connected. Hope this helps.

If the truck has a trailer harness I would check there for corrosion in the conections

Hello. Definitely check the fuses, but also check the ground for the lights in the rear end as your symptoms could also be the result of a poor ground.

if it has a trailer package look at the splitter when you take off the tail light cover might be that plug.

replace flasher

I would guess the brake fuse ( this does not use the same fuse as the tail lights/blinkers) or the ground for the brake light bulb.

Did you check the tailight relay under the hood?
