Mini Cooper Fan Not Turning On? Check the Relay Switches!

Is your Mini Cooper cooling fan not working or is your car overheating? In this video, I show you how to quickly diagnose a dead or missing radiator fan relay by swapping R3 (Low Speed) and R4 (High Speed) in the engine bay fuse box. This is a simple 5-minute test you can do before buying an expensive new fan motor! Can also save a trip to a garage.
