Why is the low speed fan not working on my Mustang?

Why is my car fan not coming on?
You should have power at the terminal on the low speed side once the car is at operating temps and then check the high speed side by turning on the AC. The high speed side should kick in shortly after the AC is on and you will get voltage there. If you get voltage on the high speed side then it is something wrong with the fan.
What should I do if my radiator fan is not working?
A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.
