Check the power distribution panel under the hood first–it contains the primary protection elements for ignition, cooling fan, and ABS, and provides faster access than the interior unit. For this PT model from the mid-2000s, the engine compartment module typically includes high-amperage links ranging from 30A to 60A, assigned to systems like radiator fan control, starter relay, and air conditioning clutch.
Inside the cabin, the secondary panel is positioned beneath the dashboard on the driver’s side. It houses lower-rated protective components (from 10A to 25A) responsible for lighting circuits, audio system, power windows, and instrument cluster. Pay attention to slot numbering: it follows a left-to-right, top-to-bottom sequence, and mismatching positions during replacement can disable multiple subsystems simultaneously.
Use the lid markings or factory chart to verify each slot. For example, interior lighting and radio memory often share adjacent positions but operate on separate lines. The horn and hazard signals are typically routed through relay-controlled paths, located either in the engine bay module or integrated into the same panel depending on trim level.
When diagnosing electrical faults, inspect not only the protective element itself but also the контакты: oxidation or slight deformation can interrupt current flow even if the strip inside remains intact. A multimeter reading of 0–0.3 ohms across terminals confirms proper conductivity. Values above this range indicate resistance buildup and require cleaning or replacement.
Always disconnect the battery before accessing any panel to prevent short circuits. Replacing components with incorrect amperage–such as installing a 25A unit in a circuit rated for 15A–can lead to overheating of wiring and damage to control modules. Keep a printed layout reference in the glove compartment for quick troubleshooting during travel.

Check the power distribution unit under the hood first when electrical components stop working; it sits near the battery and contains high-amperage links for critical systems such as the starter, cooling fan, and ABS module.
The interior protection panel is mounted beneath the dashboard on the driver’s side. Access requires removing a small cover panel; inside, each slot corresponds to circuits like radio, interior lighting, and power windows. A plastic puller tool is often clipped inside for safe removal of elements.
Each slot is marked with a number and amperage rating. Use the labeling chart printed on the cover or in the owner’s manual to match the correct circuit. Installing a higher-rated element risks wiring damage, while a lower rating may cause repeated failures.
Common assignments inside the cabin panel include:
- Slot 1 – instrument cluster
- Slot 4 – brake lights
- Slot 8 – windshield wipers
- Slot 12 – audio system
- Slot 16 – air conditioning control
Under-hood distribution typically includes larger cartridge-style protectors. These handle:
- Engine control module
- Radiator fan motor
- Ignition system
- Transmission control
If a component fails intermittently, inspect for corrosion or loose contacts rather than replacing the element immediately. Moisture intrusion near the engine compartment unit can lead to unstable electrical flow.
Use a multimeter to verify continuity across the metal strip. A visual check is not always reliable, especially with hairline breaks. Testing ensures accurate diagnosis before replacing parts.
Keep spare elements of common ratings (10A, 15A, 20A) in the glove compartment. Quick replacement on the road reduces downtime and helps isolate whether the issue is a simple overload or a deeper wiring fault.
Exact placement of interior and engine bay fuse boxes in the 2007 PT Cruiser with access instructions
Open the driver-side door and remove the small plastic cover at the end of the dashboard panel to reach the cabin electrical module; the panel edge facing the door conceals the latch, and a flat trim tool helps release it without cracking the clips.
The interior unit sits to the left of the steering column, slightly below the air vent line, mounted behind a rectangular trim piece; tilt the cover outward from the top edge first, then pull straight to disengage the lower tabs, ensuring no wiring harness is disturbed during removal.
Engine compartment power distribution location
Lift the hood and locate the main power distribution center on the left side near the battery; it is a black rectangular housing secured with snap-fit tabs, and pressing both side latches simultaneously allows the lid to lift cleanly without forcing it.
Inside the engine bay housing, the relays and high-amperage protection elements are arranged in rows; access requires steady upward pressure on the lid hinge after unlatching, and it is advisable to keep the cover aligned to avoid bending the plastic hinge pins.
Access tips and handling precautions
Before interacting with either compartment, switch off ignition and disconnect the negative battery terminal to prevent accidental short circuits; use a flashlight to identify components clearly, and avoid pulling any element at an angle, as the connectors are tightly seated and can loosen from repeated improper handling.
