You can disconnect the connector to the fan and check to see if you have power at one of the large metal flat pin. If you have power then you know that the fuse is o.k. If you don't have power then you know that the fuse is blown. The only reason why that fuse (50 amps that's right 50 amps) fuse will blow is because there was a short in the fan circuit. The only electrical components on that circuit is the fan. If the fuse is blown you need a new fan.

Another way to test if the fan is o.k is if you have software program to communicate with the truck. The right program can check for faults and can command the DME to turn the fan on.

Search my posts for fan problem and solution.
