Are you sure the radiator fan isn't working? The fan only turns on when certain conditions are met, such as the coolant going above a certain temperature.

Which relays did you pull to test, and which circuits are those tied to? This is the best starting point. Check your manual for reference.

Disconnect the battery for 20-30 min.
