There is power in the ground wire to the radiator fan & it makes the fan not blow so the engine overheats. How do you fix this? A test on the plug showed power in the ground wire that goes to the radiator. The fan was also tested & it will work without the ground wire. How do we get the power out of that wire so the car won't overheat?

If you have power in a ground, there has to be a short to power. Basically, a power wire is supplying power to the ground. Usually, that will blow a fuse. Follow the ground wire to see if you can find the short.

Or you can cut the ground wire at the fan motor temporarily for a test and take it straight to the battery negative terminal and see what happens
