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.

Last year my fuel gauge and turn signal fuse blew. This year it happened again, however, when I replaced the fuse, it blew as soon as I turned on the car. Any ideas on where to find a short or cause?

I would start by getting a wiring diagram and find what these two seemingly separate systems have in common, or where they overlap. That might narrow down the possibilities. If they have nothing in common, then I would suspect the fuse box itself.

Why does my turn signal fuse keeps blowing as soon as I put it in?

You have a point in your turn signal wiring that is shorted to earth, you may be able to determine what side it's on if it only blows when you turn them on one way, you should check each bulb holder by removing all the turn bulbs and turn the signal on, if it flashes on the instrument cluster (will be rapid flashing) then the issue will be with one of the bulb holders, try putting the bulbs in one at a time and if it stops working you have found the corner of the car where the issue is an should be able to find the fault from there

As soon as I put a new fuse and hit the turn signal it blows the fuse right away even if I TURN THR HAZZORDS ON THE FUSE WILL BLOW

is the fuse a 15 or higher, if so you probably have a dead short in the wiring, like the positive wire is touching metal somewhere on the body or chassis
