2007 dodge ram 2500 5.9 cummins. My brake lights will not come on. cab brake light works fine. blinkers work. tail lights work. changed the bulbs and checked the fuses. still no luck. i think a trailer i pulled was wired up wrong and when i plugged it into my truck it messed something up.

if there is a tow option on that truck check the wiring on the socket for the trailer.and where thy tie in to the rear lites sometimes ther is a short.hope this helps.lucas

Bad light bulbs are a good place to look...have you replaced any lately. Look for a bulb where the filiment may be broke and laying against the filiment below it. I would suspect the stop light bulbs first.

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.

It may be the switch on the brake pedel.Hope this helps.

could be unrelated problems.check taillight bulbs,check inline 2 amp fuse to the radio,sometimes they are a spade type fuse into the back of the radio

check the electrical plugs under the bed,very back just behind the bumper should be a three way plug, make sure there not loose or disconnected.

If you have a beebing noise every time you press on the brake, it is because a tail light is burnt out. There are two filaments in each brake light. Therefore, when you turn on your hazards, it will appear that both tail lights work properly. The beebing warning sound is actually a feature that Dodge put in the Rams so drivers would know their tale light is out. Just replace the tail light bulb, and the beebing will automatically cease. To get the tail light housing out, you will need a torex screw driver. Also, you twist the bulb housing out as opposed to pulling it out. There are three prongs that twist out.

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,

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.

The could be broken relay or the wiring socket is out please check all the connection , if not then turning switch is defective............
