My 1992 Dodge dakota's brake lights don't work. Checked fuses, none blown. Even hooked up a trailer and checked brake lights on that and still nothing. Please help. Just fixed other stuff on it and dont want to dump any more money in it. Please help!

The trailer plug wiring just taps into the truck harness to the rear lights so if the truck lights work, the problem is in the wiring, not a fuse.

look for fusible links that go to the bed. not it? then look for broken ground wire under the bed.

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 :)

any half *** wiring job could do a number of things from no lights to no radio if its half *** then its not worth a hoot i would have the trailer brake removed unless you plan on using it then i would have a shop redo it trailer brakes when half *** installed can cause problems i prefer a whole *** job rather then a half *** job any day.

You may have blown out your brake fuses. if you have not already checked this or dont know how then bring it into a shop and then can most likely test it for free and replace it for less then $20.

Why would it be a fuse?
You have front parking lights? Then no fuse

If it was a fuse ---would that fix it -- NO it wouldn't
Why do fuses blow?

Have you even removed the tail light housing & checked the bulbs,
or checked the sockets for ground or under truck for wiring
harness issues?

Don't need a manual to check all fuses under the dash &
in the box near brake booster

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

Check these;
Brake lights, backup lights. cabin lights.
None of these are controlled by the light switch which seems to be the problem. You may need a voltmeter to track this down.

A long shot is to check the fusible links under the hood. They are essentially fuses by another name. They are sometimes located in gang boxes and even one of the '+' cables coming off the battery if it has two cables.

Hi the first thing I check on for anyelectrical problem is a bad ground connection. Follow the headlight wires as far as you can, even when they disappear into a larger covered loom at random places, maybe even right next to each light, you will find a wire or several attached to ground, could be a inner fender, engine, etc.. sometimes a inner fender ground is just a selftapping screw, It may be rusted out or just loose. Headlights work through relays that are also located in the fuse boxes. I assume you have checked both fuse boxes, in the truck and under the hood, good luck, Chuck

If you have a trailer plug installed trace the wires to see if there is a bare spot or broken wire.If no plug then you need to check for bare wire or broken wire from tail lamp assemblys to where the wire plugs into main wireing harness.
