Locate the interior and engine compartment power distribution units first, then match each slot number with its assigned circuit before removing any insert. In most configurations, the cabin panel sits behind a lower dashboard cover near the steering column, while the engine compartment unit is mounted next to the battery under a plastic lid with clip locks.
Each insert is marked with an amperage rating such as 10A, 15A, or 30A, which must be matched exactly during replacement. Lower ratings protect lighting, infotainment, and control modules, while higher values serve systems like cooling fans or power windows. Pulling a higher-rated insert into a lower-rated slot risks wiring damage, so always verify labeling printed on the cover or service sheet.
Use a test light or multimeter to confirm a failed element before swapping parts. A broken metal strip inside the insert indicates failure, but electrical testing provides certainty. Check both contact points with ignition on; lack of voltage on one side signals a blown component. Keep spare inserts of common ratings in the glove compartment for quick roadside fixes.
Relay blocks positioned alongside these panels manage high-load circuits such as fuel pumps and starter control. Clicking sounds during ignition attempts can help identify working relays, while silent units may require inspection or replacement. Always disconnect the battery negative terminal before handling these components to prevent short circuits.

Check the legend printed on the cover panel before touching any slot, as it maps each position to a specific circuit such as headlights, ECU, or HVAC. This reference saves time and prevents removing the wrong insert.
The interior power distribution unit usually contains low to mid-range ratings between 7.5A and 20A, handling systems like dashboard electronics, audio, and interior lighting. The engine compartment unit includes higher values such as 30A to 80A, assigned to cooling fans, ABS, and ignition-related components.
Typical circuit assignments
- 10A – cabin lights and control switches
- 15A – cigarette lighter and accessory socket
- 20A – wiper motor and washer system
- 30A – power windows and seat adjustment
- 40A+ – radiator fan and main electrical supply
Match the slot number with the printed scheme rather than relying on position alone, as layouts differ by production year and engine type. A mismatch can disable unrelated systems or leave the actual issue unresolved.
Relays located рядом act as electrically controlled switches for high-load systems. They are typically marked with codes like R1, R2, or labeled for functions such as starter or horn. Swapping identical units temporarily can help confirm a faulty relay without special tools.
Visual inspection steps
- Remove the insert using plastic pullers
- Inspect the metal strip for breaks or burn marks
- Check for discoloration indicating overheating
- Reinstall only if the strip is intact
Use identical amperage during replacement; installing a higher-rated insert may allow excessive current and damage wiring harnesses. Keeping a small set of spare inserts in common ratings helps resolve minor electrical faults without delay.

Open the driver-side lower dashboard panel to reach the interior power unit, typically positioned behind a small plastic cover near the steering column. The panel is secured with clips and can be removed by pulling gently from the edge.
This interior unit handles circuits related to cabin electronics such as lighting, infotainment, and control switches. Access is usually possible without tools, though a trim removal tool helps avoid scratching plastic surfaces.
Check the left side of the dashboard if the main cover is not visible, as some configurations place the panel behind a side cap accessible only when the driver door is open. The cap snaps out with light pressure.
The engine compartment power distribution unit is located next to the battery or along the fender wall. It is covered by a sealed plastic lid with locking tabs designed to protect components from moisture and dirt.
Release the locking tabs carefully and lift the cover upward to expose high-amperage inserts and relay units. The underside of the lid usually contains a printed layout showing slot numbers and circuit assignments.
Space around the battery can be tight, so move cables slightly if needed, but avoid disconnecting terminals unless necessary. Contact with metal tools near exposed terminals can cause short circuits.
Ensure ignition is off before accessing any electrical distribution unit, and remove the key from the ignition to prevent accidental current flow. For added safety, disconnect the negative battery terminal when working in the engine area.
After inspection or replacement, press all covers back into place until clips lock firmly. Loose covers may allow dust or moisture inside, leading to corrosion or intermittent electrical faults.
