100 AMP Fuse ReplacementNot sure , but if your talking about the 100 amp fuse in the fuse box under the hood,,here goes.... Assuming you already have the fuse box cover off,,,,remove the battery to get it out of the way,,,remove the two bolts holding the fuse box ,,,the bottom of the fuse box comes off by depressing on each side near the bottom,, locate the large black and white wires that go into the fuse,,you'll need a screw driver to un-lock the fuse and fuse holder,,pulling slightly on the wires while depressing the latch ,,it should come out from the bottom,,,the two wires are bolted on to the fuse, remove the bolts and the fuse should slide out of the fuse holder,,,install new fuse,,bolt the wires back in place, insert the fuse and fuse holder back into the fuse box, replace the bottom of the fuse box, rebolt to the car,,re-install battery...New fuse cost about $10 from Toyota Dealer.If this is not what your asking for,,maybe it will help someone else.

A circuit that keeps blowing a fuse, is caused by a Short in that circuit, loose connections causing arching, overloaded circuit, or a fuse that is too small for the circuit load. Do not install a fuse bigger than the circuit was designed to handle. Someone may have install too small a fuse. Check fuse list and see if the proper fuse is installed.

It can cause a fire. The circuit is protected by the 5 amp fuse. This fuse is protecting the wiring in the circuit from overheating and catching fire. Install a 10 amp fuse and the protection is lost. Very dangerous to substitute a larger fuse.
Electrical short. Unless your fuses are located in your steering column (probably not) in which case it's possible that it's a blown fuse.
