How to Replace an Auto Mini Blade Fuse (4 Steps)
01
Locate & Identify
Turn off the ignition. Locate the fuse box and find the blown fuse corresponding to the failing component.
02
Remove
Use a fuse puller tool (or needle-nose pliers) to gently pull the fuse straight out. Do not twist, as this may damage the terminals.
03
Inspect & Match
Verify the fuse is blown (look for a broken filament inside). Ensure the new Tonful fuse has the same Amperage (A) and Voltage (V)rating.
04
Insert & Test
Align the blade terminals and push the new fuse firmly into the slot until it sits flush. Turn on the ignition to verify the circuit is working.
