Engine Compartment Relays

The engine compartment also houses several relays essential for various systems:

• Fuel Pump Relay: Controls power to the fuel pump.
• Ignition Relay: Controls power to the ignition system.
• ECM Relay: Powers the Engine Control Module (ECM).
• Starter Relay: Engages the starter motor.
• A/C Clutch Relay: Activates the air conditioning compressor clutch.
• Headlight Relays: Control the high and low beam headlights.
• Horn Relay: Activates the horn.

Passenger Compartment Fuse Box (Dash Kick Panel)

This fuse box, located on the driver's side kick panel, typically protects interior electrical components, accessories, and some lighting circuits. You may need to remove a small access panel to expose the fuses. Always consult your vehicle's owner's manual or the diagram on the fuse box cover for the precise layout.

Fuse #	Amp	Color	Circuit / Component Protected
1	10A	Red	Radio/Infotainment
2	15A	Blue	Power Outlet (Cigar Lighter)
3	10A	Red	USB Ports
4	10A	Red	SRS Airbag System
5	7.5A	Brown	Interior Lights
6	15A	Blue	Brakes (Stop Lights)
7	10A	Red	Turn Signals / Hazard Lights
8	20A	Yellow	Power Windows (Driver)
9	15A	Blue	Power Windows (Passenger Front)
10	10A	Red	Heated Seats (Driver)
11	10A	Red	Heated Seats (Passenger)
12	7.5A	Brown	Instrument Panel
13	15A	Blue	Wipers (Rear)
14	20A	Yellow	Door Lock Actuators
15	10A	Red	Mirror Adjust
16	10A	Red	ABS/VDC Indicator
17	7.5A	Brown	Cabin Fuse (Various low-current)
18	10A	Red	Sunroof (if equipped)
19	15A	Blue	Combination Meter
20	10A	Red	TPMS (Tire Pressure Monitoring)

Passenger Compartment Relays

While fewer than the engine bay, the passenger compartment fuse box may contain a few relays for systems like:

• Accessory Relay: Powers certain accessories when the ignition is on.
• Power Window Relays: Control power to the power windows.
• Door Lock Relay: Controls the central locking system.

How to Test a Fuse

Testing a fuse is a straightforward process:

1. Locate the Fuse Box: Identify the correct fuse box for the circuit you're troubleshooting.
2. Identify the Suspect Fuse: Consult the fuse box diagram to find the fuse associated with the malfunctioning component.
3. Visual Inspection: Most fuses have a small wire or filament inside. If this wire is broken or melted, the fuse is blown. Many modern fuses also have a small test point on top, allowing for easier testing.
4. Use a Fuse Tester or Multimeter: For a more definitive test, use a fuse tester or set a multimeter to the continuity setting. With the fuse removed from its slot, touch the probes to the metal terminals of the fuse. If the tester lights up or the multimeter beeps (indicating continuity), the fuse is good. If there's no light or beep, the fuse is blown.
5. Replace with Correct Amperage: If the fuse is blown, replace it with a new fuse of the exact same amperage rating and physical size. Using a fuse with a higher amperage can lead to serious electrical damage or fire.

Always turn off the ignition and disconnect the negative battery terminal before replacing any major fuses or relays.

Common Blown Fuses on This Vehicle

While any fuse can blow, some are more commonly affected due to their circuits' usage or design:

• Cigar Lighter / 12V Outlet (Fuse 2, 15A, Passenger Compartment): Often blown due to overcurrent from charging multiple devices or using high-power accessories. If your phone charger or air compressor stops working, check this fuse first.
• Radio/Infotainment System (Fuse 1, 10A, Passenger Compartment): Issues with aftermarket radio installations or short circuits within the system can cause this fuse to blow. If your radio is dead, verify this fuse is intact.
• Headlights (F-1, F-2, 15A, Engine Compartment): While less common with modern sealed-beam units, a short in the wiring or issues with the headlight assembly can cause these to blow. If one or both of your low beams are out, check these fuses.
• Blower Motor (F-11, 20A, Engine Compartment): A failing blower motor or an obstruction in the blower fan can cause excessive current draw, leading to this fuse blowing. If your HVAC fan isn't working, this is a prime suspect.
• Brake Lights (Fuse 6, 15A, Passenger Compartment): If your brake lights suddenly stop working, this fuse is the first place to check. It's often simple short in the wiring or a faulty brake light switch.

Always verify the printed legend in the fuse box lid against your owner's manual, as minor trim variations can occur.
