I've got a P0480 code on my 2006 Grand Caravan SXT 3.8L. I just ordered the fan relay. Fingers crossed!

If that relay is in the fuse and relay center (IPC by the battery), you have sereral relays there that can be swapped, one for the other. If fact there may be a spare relay or atleast a place to put one. (mine has such a space).

Tried the battery trick (code stayed). I will look at the connections now.

Haynes Manual says the following for P0480:

Low-speed fan control relay circuit malfunction

Perhaps a new relay is needed. I have had no first hand experience with this code myself, but others on here most likely have.
The wiring diagram can be found using this method:

I have a code now P0480, what should I do to resolve this problem. Also how do I reset or delete the codes?

Code P0480 is Cooling Fan Relay 1 Control Circuit according to http://www.allpar.com/fix/computer-codes.html

Could be a glitch. Disconnect negative battery terminal for a few minutes, say 10, reconnect and see if the code is still there.

Could be real. Best to check the connections to the cooling fans for corrosion and tightness. Check the fan operation (turning on and off rather than being always on or always off.
