[High-Performance Specs] Heavy-duty 12V DC 40A 5-Pin SPDT (Single Pole Double Throw) relay designed for precision circuit control. Features high-conductivity silver alloy contacts and a built-in resistor for transient suppression, protecting sensitive vehicle electronics and ECMs from voltage spikes. [Broad Vehicle Compatibility] Engineered as a direct professional-grade replacement for OEM # 15328865, 12193602, 15-81106, 13506836, and 96263403. Perfectly compatible with Chevy Silverado/Tahoe/Suburban, GMC Sierra/Yukon, Buick, Cadillac, and Pontiac models across a wide range of years. [Application & Troubleshooting] The ultimate fix for common electrical failures: resolves issues like cooling fans not spinning (preventing engine overheating), fuel pump priming failures (engine won't start), or erratic A/C compressor behavior. Ideal for troubleshooting Diagnostic Trouble Codes (DTCs) related to relay circuit malfunctions. [Rugged Construction & Sealed Design] Built to withstand the harshest engine bay conditions. The resin-sealed, vibration-resistant housing protects internal components from dust, moisture, and extreme temperatures (-40°F to 221°F). Each relay undergoes 100% functional load testing before shipping to ensure industrial-grade reliability. [Cost-Effective 2-Pack Value] Includes 2 high-quality relays, providing an immediate fix and a spare for your glove box or fuse box. Standard blade terminal design ensures a "plug-and-play" installation—no specialized tools or wiring modifications required for a professional-standard repair.

Restore Your Vehicle's Electrical Integrity with Professional-Grade Relays

When your vehicle’s cooling fan stops spinning or the engine fails to turn over due to a fuel pump issue, a faulty relay is often the hidden culprit. This 2-Pack 15328865 12V 40A 5-Pin SPDT Automotive Relay is engineered by specialists to provide a reliable, long-term solution for GM vehicle owners and DIY enthusiasts alike.

Why Choose Our Relays?Unlike generic alternatives, our relays feature a built-in suppression resistor. In modern vehicles, switching an inductive load (like a fan motor) can create a massive voltage kickback. Our resistor-protected design absorbs this energy, shielding your vehicle's expensive Engine Control Module (ECM) from potential damage.

Versatile & Reliable PerformanceWhether you are fixing a "clicking" sound in the fuse box or replacing a burnt-out fan control relay to prevent overheating in summer traffic, these 40A heavy-duty units are up to the task. They are designed for high-current applications including:

• Cooling Fan Control: Keeps your engine at the optimal temperature.

• Fuel Pump Systems: Ensures consistent fuel delivery for reliable starts.

• A/C & Horns: Restores comfort and safety functions instantly.

Professional Quality for DIYersTested to exceed 100,000 cycles, our relays are built with premium silver alloy contacts for minimal voltage drop and superior heat resistance. The standard 5-pin layout makes installation a 30-second job—simply pull the old relay and plug this one in. Don't get stranded by a simple electrical failure; keep these spares in your toolkit today.
