Understanding Your Corolla’s Headlight System
Before we dive into the specifics, it’s good to understand the basic components. Your Corolla’s headlight system relies on fuses for overcurrent protection and relays to switch the higher current for your headlights on and off. If one of these fails, your headlights won’t work.
2009-2013 Toyota Corolla Headlight Fuse & Relays (E140)
If you own a 2009, 2010, 2011, 2012, or 2013 Toyota Corolla (also known as the E140 generation), here’s where to look:
- Locate the Main Fuse and Relay Box: Pop the hood of your Corolla. The main fuse and relay box is conveniently located on the passenger side of the engine bay.
- Access the Fuses: Lift the lid of the fuse box. You’ll find a helpful diagram printed right on the underside of the cover, indicating the position of each fuse and relay.
- Main Headlight Relay: This is the primary power switch for your headlights. If multiple headlight functions are out, this is a good place to start your diagnosis.
- Dimmer Relay (High/Low Beam Relay): This crucial relay controls the switching between your high and low beams. If only one beam type (high or low) isn’t working on both sides, this relay could be the issue.
- High Beam Fuses: You’ll find two 10-amp fuses specifically for your high beams. If your high beams are out, check both of these first.
- Low Beam Fuses: Similarly, there are two 10-amp fuses dedicated to your low beams. If your low beams aren’t illuminating the road, these are the fuses to inspect.
2014-2018 Toyota Corolla Headlight Fuse & Relays (E170)
For 2014, 2015, 2016, 2017, and 2018 Toyota Corolla models (the E170 generation), follow these steps:
- Locate the Engine Bay Fuse Box: Open your hood and look towards the right side of your engine bay. You’ll spot a large black fuse and relay box.
- Open the Lid: Lift the lid to reveal the fuse and relay diagram, which will guide you to the correct components.
- Main Headlight Relay: This relay is central to your headlight operation.
- High Beam Fuses: Your high beams are typically controlled by the headlight relay and protected by two 10-amp fuses (often red). If either of these fuses fails, both high beams will cease to function.
- Low Beam Fuses: The low beams also run through the headlight relay and are protected by two additional 10-amp fuses (also commonly red). If these fuses blow, both low beams will go out.
2019-2025 Toyota Corolla Headlight Fuse & Relays
If you own a newer 2019, 2020, 2021, 2022, 2023, 2024, or 2025 Toyota Corolla, the fuse box location for headlights is different:
- Locate the Driver’s Side Fuse Box: Pop your hood and look for the fuse box on the driver’s side of the engine bay, usually under a protective cover.
- Access the Fuses: Press in on the tab and lift the cover to gain access to the fuses.
- Right-Hand Headlight Fuse: You’ll find a 10-amp fuse specifically for your right-hand headlight.
- Left-Hand Headlight Fuse: Likewise, there’s a separate 10-amp fuse for your left-hand headlight. If one of your headlights is out, check its corresponding fuse first.
- Daytime Running Light (DRL) Fuse: Don’t forget the 7.5-amp daytime running light (DRL) fuse. This fuse is always energized, regardless of whether your high beams or low beams are on, ensuring your DRLs are functioning. If your DRLs aren’t working, this is the fuse to check.
Conclusion
And there you have it! Now you’re equipped with the knowledge to find and inspect the essential fuses and relays that power your Toyota Corolla’s headlights across various model years. Identifying a blown fuse or a faulty relay is a crucial first step in troubleshooting headlight issues.
