The 10-Second Test Shops Charge You $100+ For
AC blowing hot at a red light. Radiator fan dead. Horn, lights or windows gone out of nowhere. Most people panic, drive to the shop and hand over $100+ just to hear what's wrong.
A lot of the time, it's one burned-out relay. It's a tiny switch under the hood that powers your AC, fan, fuel pump and more. When it dies, everything it controls dies with it. Ignore a bad fan relay and your engine can start running hot.
RelayCheck Pro gives you the answer on the spot. Clip it to your battery, plug in the relay and hit test. Green means good. Red means you found your problem. No guessing, no swapping random parts, no diagnostic fee.
