heres what you do very simple get a test light not a cheap one but a decent one, take the ground cable off the battery take the pointed end off test light and stick on the neg cable terminal take the clamping end of the test light and clamp to neg post of battery, hook the pos cable back on the bat the test light will light, then you remove one fuse at atime from the fuse box watch the light the doors need to be shut after you pull each fuse untill you find the fuse that causes the test light to go almost out, untill you find the correct fuse replace them back in the fuse box a very dim lght will be normal for such things as the clock and memory on radio and keyless entry if you have it, tremember to shut the door after each fuse is pulled if there is a under hood light pull the bulb so it will not cause the test light to glow, and do one fuse at atime .got it

Well I ended up finding out that the circuit breaker that conrols the seats, windows, trailer harness, and power antenna was getting really hot when the ingition was off. I am assuming that the trailer harness is grounding out or something.
