I have a 2004 pacifica and the radiator fans won't come off even when the car is off. I am getting a p0480 cause the check engine light came on too. This is causing the battery to die and I need to get a boost all the time now.

 

Probably the fan relay:

Either a blown fan relay or a burned fan motor.

 

I replaced the fan relay and it's working fine now. Thanks for the help!
