About this item

Car guys and gals, if your A/C is acting up or your radiator fan isn't kicking in properly, these relays might be exactly what you need! This 2-pack gives you a spare, because let's face it - when one goes, the other might not be far behind.

These are 4-pin, 12V DC relays that can handle serious current - we're talking 30A/40A, which is more than enough for most car A/C systems and radiator fans. The nylon shell is tough enough to handle engine bay heat and vibration, while the brass pins resist corrosion and ensure solid electrical connections.

Here's how they work: when your car's interior temperature gets too high, the sensor triggers the relay to turn on the A/C cooling. When it reaches the perfect temperature, the relay cuts power. This cycling keeps your cabin comfortable and reduces driver fatigue on long trips.

Installation is straightforward - just match up the wires to the correct pins. They're waterproof too, so rain or splashes won't cause issues. Perfect for cars, trucks, SUVs - basically anything with an A/C system. Keep your cool (literally) with reliable relays that won't let you down when you need them most!
