The Alphard fuses that are behind the passenger lower glove box are hidden.
First remove the door of the glove box and the small panel right in the front corner next to the door, there is a plastic covered screw that has to be removed to get the small panel out, no tools just unscrew with your fingers.This panel also has the fuse diagram printed on it.
At first inspection it looks like there are no fuses present, but if you get yourself a torch and get right under the panel and look up,you will see the fuses,they face down towards the floor.
Once you have found them good luck getting to them as there is not much room.
