Keep high-current circuits switching cleanly with the Bosch relay 0986AH0115. This Bosch Micro Relay lets a low-current control signal switch a heavier electrical load. It fits many vehicles, among them the 1999-2014 Chevrolet Silverado 1500, 2010-2018 Chevrolet Equinox and 1999-2014 GMC Sierra 1500. See the "Vehicles it fits" section for the full list and engine details.
Depending on the vehicle, this relay is cataloged for circuits such as the fuel pump, horn, HVAC blower motor and diesel glow plugs.
- High-capacity switching: As a Micro relay, it is rated to handle up to 25A.
- OE quality and design: Built to exact Original Equipment standards for fit, form and function.
- Robust construction: Made with high-quality materials designed to withstand extreme temperatures and vibration.
- Switching life: Engineered for up to 250,000 switching cycles.
A relay carries the heavy current so the control switch does not have to. This helps reduce switch load and helps prevent voltage drops to components such as headlights, fans and pumps.
Signs a relay may need replacing include a component that won't turn on, works only intermittently, or stays on after it is switched off. Fuses, wiring or the component itself can cause the same symptoms, so diagnose the circuit first. If a failed relay is the cause, this Bosch auto relay replaces it.
