P0481 help please...
I've ran into a wall here. The relays are both good, and i've borrowed a good pcm. My haynes manual doesn't have a diagram for the cooling fan system. All I can see is that a dark blue wire runs from the pcm to the 2/3 relay. Is there one wire for each relay, 2 and 3, that runs to the pcm, or just one for both relays?

Not yet. The low speed still works fine, check anyway?? It probably doesn't matter, but when I try to manually command them on with hptuners I dont hear a click at the relays like I do for the low speeds..obviously. If I had a diagram and could see where all the damn wires run from the 2/3 relays it would help, versus having to pull **** apart and trace wires.

I checked continuity on the blue 2/3 relay wire from the plug by the pcm to both on the fuse block, nothing. Guess I have a break somewhere in the signal wire. Simple enough fix..
