    Fuse/Wiring Problem?

    Everything worked in my car a couple months ago.

    Randomly one day gas/temp/and rpm gauge's die. As well as air/heat from blowing out.

    A fuse blew...

    I replace it and everything works perfectly again...a few miles down the road, it blows again. It will continue to blow no matter how many times I replace it.

    Anyone know where there could be something grounded out or what's the dealio? Not an expert at this stuff lol. Any help appreciated.

    Exactly.
    It is unlikely that anything in that circuit is drawing too much amperage to cause that fuse to blow.
    It is more likey that you have a short to ground on the power side of the curcuit.(power touching ground before the load in the circuit)

    Know how to read a wiring diagram?

        I found the issue heh. The wiring going through shifter boot. (I am guessing for reverse lights?) And now everything works without fuse blowing. Just no reverse lights lol.

          Ive heard that wire in the shifter boot is a frequent culprit. Good you found it.

          Did you throw in a SSK while you were at it???....<smile>

                Used a response on another forums first and just unplug that wire and it helped so I didnt have to. But if I run into anymore problems I definitely will.
