Knowing how to replace a car fuse may prevent you from getting stranded or allow you to get your heater working again on a cold day, providing that you have the proper spare fuses on hand. There are several different types of fuses, depending on the car’s age and manufacturer. Each of these come in different values, and it’s important to use the proper replacement.
The most common type of fuse in modern vehicles is the blade type. These are normally plastic and come in four different sizes, low-profile mini (APS or ATT), mini (APM or ATM), regular (APR, ATC, or ATO), and maxi (APX). Many older automobiles built in North America use glass fuses (SAE J554) while some older European vehicles use Bosch type fuses (DIN 72581/1). Some vintage British cars use Lucas type fuses. When replacing a Lucas type fuse with a different type its important to halve the value as the Lucas fuses use a different rating system.
