Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Hello. Welcome to Just Answer. Please allow me to assist you. The fuse panel must be unbolted form the vehicle to access the clasps that hold the top part of the fuse panel to the bottom part of the fuse panel. Disconnect the battery cables before you unbolt the fuse panel. Then unbolt the fuse panel. Looking at the panel you will see that there is a top and a bottom half. Once the panel is disconnected, the clasps that holds the top to the bottom need to be defeated to allow the bottom to detach form the top. Once the bottom is lowered, you can access the small bolts that holds the 120 amp fuse to the fuse panel buss bar. This cannot be done by having the panel bolted to the vehicle, it Must be released by removing the mounting bolts.
