2019 Toyota RAV4 Fuse Box Diagram & Amperage

Quick Answer

The 2019 Toyota RAV4 typically has three main fuse box locations: under the hood, behind the glove compartment on the passenger side, and in the cargo area on the driver's side.

Under-Hood Fuse Box (Engine Compartment)

This fuse box, located in the engine bay, houses fuses and relays for critical engine components, lighting, and other high-current systems. Always refer to the diagram on the fuse box lid for exact configurations, as they can vary slightly by trim level and options.

Relay Locations: Within the under-hood fuse box, you'll typically find relays for components such as the Starter, EFI Main, Headlight (High and Low Beam), Cooling Fan, and A/C Magnetic Clutch. Their exact positions are usually marked on the fuse box lid.

Passenger Side Fuse Box (Dash/Kick Panel)

This fuse box is often located behind the glove compartment or in the passenger side kick panel area. It controls various interior electrical accessories and comfort features.

Relay Locations: Common relays in this fuse box include those for the Blower Motor, Wipers, and main body ECU functions.

Cargo Area Fuse Box (Driver's Side)

Located on the driver's side of the cargo area, often behind a removable panel, this fuse box controls power to various rear-mounted accessories and sometimes includes additional fuses for towing or specialized equipment.

Relay Locations: If equipped with a power back door, you might find a relay for it here. Towing relays for specific trailer functions can also be present.

How to Test a Fuse

Testing a fuse is a straightforward process. You will need a multimeter or a fuse tester.

1. Locate the fuse: Identify the suspected fuse using the diagrams above and the legend on your vehicle's fuse box cover.
2. Turn off the ignition: Ensure the vehicle's ignition is off to prevent electrical surges.
3. Remove the fuse: Use the fuse puller (usually found in the under-hood fuse box or with the spare fuses) to carefully remove the fuse. Avoid using pliers that might damage the fuse or its contacts.
4. Visual inspection: Hold the fuse up to the light. If the metal wire or strip inside is broken or melted, the fuse is blown and needs replacement.
5. Test with a multimeter (for less obvious breaks): Set your multimeter to the continuity setting (usually indicated by a symbol resembling a sound wave or diode). Touch the probes to the two exposed metal tabs on top of the fuse. If the multimeter beeps or shows a reading close to zero ohms, the fuse is good. If there's no continuity or an "OL" (open loop) reading, the fuse is blown.
6. Replace with the correct fuse: Always replace a blown fuse with a new one of the exact same amperage (A) and type. Using a fuse with a higher amperage rating can lead to serious electrical damage or fire.

Common Blown Fuses on This Vehicle

While any fuse can blow, some circuits are more prone to issues due to frequent use or component wear. On the 2019 Toyota RAV4, keep an eye on these common culprits:

• Cigar Lighter / 12V Power Outlets (P/OUTLET NO.1 & NO.2, CIG): These fuses often blow due to overcurrent from connected devices, faulty chargers, or foreign objects inserted into the outlet. If your phone charger suddenly stops working, these are the first fuses to check.
• Blower Motor (A/C BLOWER): If your climate control fan stops working on all speeds, this large fuse is a likely suspect. A failing blower motor or a blockage in the HVAC system can draw excessive current.
• Headlights / Tail Lights (H-LP, TAIL): While less common with modern LEDs, a momentary short or bulb failure (if still using incandescent) can cause these fuses to blow. If an entire section of your lighting is out, check here.
• Radio / Infotainment (RADIO): Issues with aftermarket installations, a faulty head unit, or even a software glitch can sometimes lead to this fuse blowing. If your entire infotainment system is dead, start here.

What to check first: Before assuming a fuse is the problem, always verify that the component itself is faulty or if there's an external issue (e.g., a disconnected cable, a device not plugged in correctly). If a fuse blows repeatedly after replacement, it indicates a deeper electrical problem that needs professional diagnosis.
