The 2008 Mazda 3 vehicle’s electrical system is protected by fuses. If any lights, accessories, or controls don’t work, inspect the appropriate circuit protector. If a fuse has blown, the inside element will be melted. Note: If the same fuse blows again, avoid using that system and consult an Authorized
Mazda Dealer as soon as possible.
