Newbie here,,,,,,Ok, so i am helping my neighbor work on his 1993 GS 300. The car has a good battery. There are no lights on the dash, gauges are not moving when attempting to turn over the car. So I checked the fuses and it appears there is a blown 100A fuse. I have never worked on a Lexus so I am unfamilar with replacing the fuses. Can someone direct me how to remove the 100a fuse in the fuse box (located in the engine compartment)? Thanks
