P0480 -on a 2005 Jeep Grand Cherokee

Question

We diagnosed our 2005 Jeep Grand Cherokee and found a code P0480 and P0481, what can we do?

Answer 1

P0480 cooling fan 1 control circuit

P0481 cooling fan 2 control circuit

What these 2 code have in common is they share the same fuse and the same relay and the same moduel. So first check fuse 23 which is a 50 amp fuse (big one), make sure its not burnt open, The next is the cooling fan relay ( its better your replace rather than swap), Because you lost both cooling fan 1 and 2 which means low speed and high speed, your basically will need a cooling fan motor
