Whether you’re working on a 2003 model or the latest 2024 version, this guide will walk you through exactly where to find the starter relay and fuse, plus how to test them like a pro. So let’s break it down by generation.

🔧 2003–2008 Toyota Corolla (E130)

Underhood Fuse Box:

1. Open the hood and locate the engine fuse box.
2. Look for a green 30-amp fuse — this is your main starter fuse.
   ✅ Pro Tip: If it’s blown and you’re in a pinch, you can temporarily swap it with the adjacent amplifier fuse. Just don’t forget to replace it ASAP!

Interior Fuse Box:

• Open the coin tray near the steering wheel or look beneath the dashboard by the pedals.
• Locate the 15-amp fuse labeled AM2.
• This powers the ignition switch, which energizes the starter relay.
• If this fuse is good, the black wire at the ignition switch will be live at all times.

🔧 2009–2013 Toyota Corolla (E140)

Cabin Fuse Box:

• Located just below the steering wheel—pull the cover to access.
• Check the 7.5-amp fuse responsible for both the starter system and power outlet.

Engine Bay Fuse Box:

• Located at the back-right corner of the engine bay, near the driver’s side.
• Look for:
  • Green 30-amp fuse – main starter fuse.
  • Blue 15-amp fuse – also related to the starting system.
• Make sure both are intact. Replace them if the metal strip inside is burnt or broken.

🔧 2014–2018 Toyota Corolla (E170) Starter Fuse

Underhood Fuse Box:

• Open the hood and locate the fuse box on the driver’s side.
• Lift the cover and inspect the following:

Key Components:

• 30-amp starter fuse – sends power to the starter motor.
• 7.5-amp AM2 fuse – energizes the ignition switch.
• Starter relay – a small purple relay near these fuses.

Quick Fix Tip:

• While someone turns the key to “Start”, tap the relay lightly with a screwdriver handle. If the relay is sticking, this might get it working again.
• If that fails, swap it with another relay with the same pin layout to test functionality.

🔧 2019–2024 Toyota Corolla (E210)

Engine Fuse Box (M20A-FKS and 2ZR-FAE motors):

• Located under the hood—open the fuse panel as shown in your manual.
• Find:
  • Starter relay – may click or stick if faulty. Tap it while turning the key.
  • Green 30-amp starter fuse – check for visible damage or breaks.

Cabin Fuse Box:

• Located just to the left of the driver’s footwell—you might need to kneel to see it clearly.
• Look for a 7.5-amp mini fuse tied to the starter control system.

Pro Tip:

If the mini fuse is blown, your car won’t even attempt to crank. You can find replacements easily at any auto parts store—just ask for a 7.5-amp mini fuse.
