Where to Find the Fuses in the Nissan Qashqai

The fuse box in the Nissan Qashqai's cabin is located to the left of the steering wheel, where there is a small cover. Pull it off to access the fuse and relay box. To replace a fuse, if that is the cause of the issue, take a small pair of pliers and remove the fuse of the non-functioning component. Check that the bridge inside the fuse is not broken; if it is broken, replace the fuse with a new one of the same amperage as the old one. If the bridge is intact, the fuse is functioning correctly.
