it can be found in the inside cover of the box just above the lever for the hood below the dashboard, also on the left side in the engine close to the battery.
Check out the fuse block under the hood near the battery. You need to remove the plastic cover, which has a diagram of the fuses below.

The fuse diagram should be in your owners manual, and also on the fuse box cover. If you don't have the manual, and there is no diagram on the fuse box cover, go to your local Nissan dealer and ask them to give you a diagram.

This answer does not address which fuse in the fuse is for the dashboard lights. I checked the fuse diagram on the back of the cover, but could not find one for dashboard/instrument panel lighting. Any suggestions? On 99 Nissan Frontier 2.4/2WD, the fuse box can be access by removing the plastic rectangular cover about your left knee high. Inside the cover is the diagram for each fuses and what it serve. There's also a plastic fuse remover on the right side of the fuse assembly, several spare fuses on top and it uses the midget(1/2")type fuse. Hope this will help. (sid5401@cox.net)
