How to test a fuse
A blown fuse can be identified in two ways:
- Visual inspection: A good fuse has an intact, unbroken filament running through its center. If this filament is broken, the fuse is blown and needs to be replaced.
- Multimeter test: Set your multimeter to the continuity setting. Touch one probe to each of the fuse’s metal tabs. If the multimeter beeps or shows a reading of zero ohms, the fuse is good. If it remains silent or shows infinite resistance, the fuse is blown.
When replacing a fuse, always use a new fuse of the same amperage rating. Using a higher-rated fuse can cause serious damage to your vehicle’s electrical system.
Common blown fuses on this vehicle
- CIG/P-OUTLET: These fuses for the 12V power outlets are prone to blowing if a faulty or incompatible device is plugged in. Check the device you’re using for any visible damage before replacing the fuse.
- H-LP LH / H-LP RH: Headlight fuses can blow due to age or a voltage spike. If a new fuse blows immediately, you may have a wiring issue or a faulty headlight bulb. Start by replacing the bulb, then check the wiring for any damage.
- WIPER/WPR: If your wipers suddenly stop working, a blown fuse is a likely culprit. This can be caused by a faulty wiper motor or by trying to run the wipers when the blades are frozen to the windshield.

Before you pull a fuse on the 2022 Toyota Corolla
- Use the label printed on the panel cover or the owner's manual for your exact build. Layouts change with options, model year and build date, so a chart for another truck can be wrong.
- Replace a blown fuse only with the same amp rating. A larger fuse can let wiring overheat.
- A fuse that blows again right away means a short or failing component downstream. Find the cause before replacing it again.
- A good fuse doesn't prove the circuit works — relays, grounds and connectors fail too.
- Disconnect the battery before working near high-current fuses or cables.
