My fan has not been turning on, I had the radiator and condenser replaced due to a fender bender and had accidentally dropped the fans electrical connector into the coolant drain pan. How do I replace it?

Did the connector break? If not, you can just clean the connector and it should be fine. Here is the wiring diagram so you can see how the fan cooling system works to turn on the fan motors. Also check the fuse #5 on the right side of the engine bay fuse panel.

The connector did not break, but the fan no longer works tested it with test leads to the battery and the fan is fine. I don’t really know what else it could be.

Usually, it will be the fan controller which is near the rear of the engine compartment. here is the location and the wiring diagrams so you can see how the system works. Also, please check the fuse # 5, 125 amp in the fuse panel right rear of engine compartment. Here is the location on the ME SFI control unit to see if you have any burned connections.
