Well, probably a bad wire between the PCM and the fuse box due to the relay
frying. But to check the fan, with a good relay in the PDC and ignition
on(truck doesn't have to be running) hook a wire from the blue wire with
pink tracer on the connector in the fuse box to ground. Should kick the fan
on. My truck has the same problem, and I just ran a manual switch for
ground to that wire until I installed my aftermarket fan.

Help, I'm a bit stuck. ('00 - 5.9 - Dak)
I know the code is for the electric fan and it is not working.
The Relay was fried so I borrowed on from the Durango. Cleared the code but
the fan still did not run. Fuse in fuse box under hood ok.
Is there any chance of an in line fuse or anything else to look for?
Like what turns it on and where is it?
Is there a way to buy pass and see if fan works?
Many thanks
Bill
