P0480-Where or what is the fan relay 1. I am not having very good luck finding this anywhere. The fan was replaced and is fairly new.

 

u2472 talks about the guage cluster
I think they are all related to the fan issue code.

I don't have the powertrain/emission manual to do a search for that relay only thing i can suggest is to follow the wires from where the clutch fan connects at the radiator shroud.

 

I see. thanks

If I'm reading the descriptions correctly these all indicate connection problems at the fan or between the instrument cluster and /or smart junction box. Any chance something got unplugged and was not plugged back in properly when the fan was worked on?

 

Thanks for that I will check again. Now that i think about it i may not have cleared the codes from before i changed the fan...oops!
