Supra Wiring/Fuse Problems Need Help!!!

yes you have a short circuit (to ground). either a wire or a connector cut or something to make contact with ground (chassis or negative) or a motor (the load for the circuit) doesn't have enough resistance. Either way theres not enough resistance in the circuit to keep the current below what its fused for. Whatever you do dont just put a bigger fuse in. The factory already has a 30% lee-way just incase of spikes. Basically your going to need a voltmeter at the least to tackle this one, the only problem is that you need to know how to use it. Im going to take a wild guess and say its probabably window switch related. but thats just because i know window switches fail quite often on other vehicles.

Sorry for the essay. If you can get a wiring diagram or manual i can probably help you further.
