Checking Fuses: Notes
WARNING: This page is about a different car, the 2004 Mitsubishi Eclipse, 2004 Dodge Stratus, and 2004 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
A blade type fuse has test taps provided to allow checking of the fuse itself without removing it from the fuse block. The fuse is okay if the test light comes on when its one lead is connected to the test taps (one at a time) and the other lead is grounded. Remember to turn the ignition switch to ON to ensure all circuits are live.
