2022 Toyota Highlander Fuses and Fuse Box | How to fix a blown fuse
The 2022 Toyota Highlander, which is known for being reliable and having high-tech features, has a full switch system to protect its electrical parts. The fuses and fuse boxes are very important for keeping the car’s important systems safe by stopping electrical overloads. The fuse box usually sits in the engine bay or the cabin’s interior. It holds a group of fuses that are meant to “blow” or break in the event of a power surge or short circuit, protecting the parts that are connected. When a fuse blows, it cuts off the electricity, which means there is a problem that needs to be fixed. The blown fuse can be changed with a new one of the same amperage rating once it has been found. This easy but important maintenance job makes sure that the car’s electrical systems, like the lights, radio, and power windows, work well, which improves the driving experience overall. The electrical system in the Toyota Highlander lasts longer and works better if it is checked regularly and blown fuses are replaced when they are needed.

After a fuse is replaced
- If the lights do not turn on even after the fuse has been replaced, a bulb may need replacement.
- If the replaced fuse blows again, have the vehicle inspected by your Toyota dealer.
If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this vehicle. Because certain bulbs are connected to circuits designed to prevent overload, non-genuine parts or parts not designed for this vehicle may be unusable.
WARNING
To prevent system break-downs and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or injury.
- Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse.
- Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix. - Do not modify the fuses or fuse boxes.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Toyota dealer as soon as possible.
FAQs
The fuse box in a 2022 Toyota Highlander is typically located in the engine compartment.
The Highlander usually has two fuse boxes: one in the engine compartment and another inside the cabin. Check your owner’s manual for details.
Fuses protect electrical components by breaking the circuit if there is an overload or short circuit, preventing damage to the components or electrical system.
Look for a fuse with a broken filament or a discolored appearance. The owner’s manual usually has a fuse diagram, or it may be printed on the fuse box cover.
You typically only need a pair of needle-nose pliers or the fuse puller tool provided in the fuse box.
No, it’s not recommended. Always replace a blown fuse with the same amp rating to avoid damaging your vehicle’s electrical system.
The interior fuse box is usually located near the driver’s sidekick panel or beneath the dashboard.
Many vehicles come with spare fuses in the fuse box or a compartment near it.
Blown fuses can result from issues like a short circuit, faulty electrical components, or overloading the system
Locate the fuse for the headlights in the fuse box, use the fuse puller or pliers to remove the blown fuse, and replace it with a new one of the same rating.
Yes, replacing a blown fuse is a simple task that can be done without professional assistance, provided you follow safety precautions and use the correct replacement fuses.
If you repeatedly blow fuses, it may indicate an underlying electrical issue. Consult a professional mechanic to diagnose and fix the problem.
Some vehicles have transparent fuses, allowing you to visually inspect them without removal. However, for most fuses, you need to remove them for a thorough inspection.
It depends on the function of the blown fuse. Certain fuses control critical systems, and driving without them may not be safe or feasible.
