The Chevrolet SSR (Super Sport Roadster), produced from 2003 to 2006, is a unique blend of a pickup truck and convertible, offering a retro-inspired design with modern performance. While its distinctive styling and retractable hardtop make it stand out, the SSR also depends on a reliable electrical system to ensure all of its advanced features function smoothly. The fuse box and relays are integral components of this system.
The fuse box in the Chevrolet SSR is responsible for protecting the vehicle’s electrical circuits from overloads or short circuits. The SSR has a fuse box located in the engine compartment and another in the cabin, typically under the dashboard. These fuse boxes manage and protect various electrical components, including the retractable roof mechanism, lighting, infotainment system, and power accessories like windows and seats. If an electrical feature fails, checking the related fuse is often the first troubleshooting step, as a blown fuse is a common cause of electrical issues.
Relays in the SSR act as electrically controlled switches that allow lower-power circuits to control high-current systems. For example, relays control the power supply to the starter motor, fuel pump, and cooling fans. A malfunctioning relay can cause significant issues, such as the engine not starting or the cooling fans failing to operate, leading to potential overheating.
Regularly inspecting and maintaining the fuse boxes and relays is essential for keeping the Chevrolet SSR’s electrical system reliable, ensuring all features, from the unique retractable roof to the essential engine components, operate as intended.

WARNING
- Never replace a fuse with one that has a higher amperage rating.
- A fuse with a too-high amperage could damage the electrical part and cause a fire.
- On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
- If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
- Terminal and harness assignments for individual connectors will vary depending on vehicle equipment level, model, and market.
