I have no brake lights, no hazzard lights, but the signal lights work. Wiring has no breaks, but the fuse blows as soon as the brake or hazzard lights are used.

There is a short somewhere-try disconnecting all components on that circuit,put new fuse and try using one,if the fuse still blows,problem is in wiring or switch unit,if not,plug one component in and a time until the fuse blow,replace component
accordingly.make sure there is no slightly shaved wire touching the chassis,this will show when all if d/c'ed and fuse still blows,good luck

1994 dodge dakota brake light ground location


The ground wiring on newer vehicles is a little complicated. Older cars, the ground would have been to the body around the tail-lights, but these have a ground wire in the harness and is connected to the turn-signal switch, and other sources. I don't think you have a ground problem. Does the fuse blow as soon as you press it into the fuse-block, or when you step on the brake? I believe you have a dead short somewhere, possibly a pinched turn-signal wire close to the tail-light assembly. Brake lights work through the turn-signal wires from the turn-signal switch on the steering column. That's how you can have one side blinking for turn while the other side stays on for brake. I'm kind of shooting in the dark here because I don't know what all you've done. If you replaced the turn-signal switch in the steering column, you may have pinched a wire or something there. Another thing, if the fuse doesn't blow as soon as you press it in, will both turn-signals work as long as you don't press on the brake? If you can provide a little more information, I might be able to help you more. One last thing....Have you replaced tail-light/turn-signal bulbs? If so, be sure you used the right bulb. You should only have two bulbs, one for back-up lights and one 1157-type combination for tail-lights and turn-signals. I have seen people use a single contact (1056) bulb in place of a 1157, which creates a short from brake/turn-signal back into the tail-light circuit. I do have a 1994 Dodge Dakota.

Brake lights turn signal and hazzards


Turn signals are on fuse number one and brake lights are on fuse number 9. Both are in the fuse box under the dash or on the side of the dash. Both are 15amp.

Where is the brake relay on a 2000 tahoe


No relay in the wiring diagram. There is a 20amp hazard fuse and a 10amp vehicle stop fuse in the engine compartment fuse box.
If those fuses are good, and the brake light switch checks out ok, I would look at the turn signal switch next.

I have a 1997 chevy silverado and I keep having a fuse blow that makes my hazzard lights and brake lights not work plz help me


If you have a trailer hook up, check that the wiring is not touching ground. Constant fuse blowing is an indication of a short to ground.

Blowing brake light fuses everytime you hit brakes.


Sounds like a short in the steering colume, maybe the turn signal switch, or a wire that the insulation got wore thru in the colume. Unhook break light switch and try the turn signals and hazards again and see what happens, maybe you can isolate it that way. Also if you havent done it already chk.the sockets in tailight housing for corrosion and bear wires, or anything, even ground wires.
