Unplug the passenger fan and put 12v to it. Saying there is a problem with the passenger side fan and not doing anything to test it does not help. At least you will narrow the problem down to the fan or the wiring. As for the fan clutch, pop the hood and spin the fan by hand. Start at the 12o clock blade and give it a nice spin and see if it continues to spin. It should not even make one complete revolution. Next get the car up to operating temp and then some then have someone turn the engine off while you watch the fan. It should stop when the engine stops. If it continues to freewheel, replace the clutch or service it with silicone. View the links.
