    If the fans are not coming it could be as simple as a bad fuse. the fans go bad also. The relay rarely fails but they do sometimes.

    In the fuse box, look for a 40amp fuse (fuse #4) replace it if it is bad, if it blows again then one of the fans is shorted or there is a short in the wiring.

    A simple way to check the relay is to swap it with a different relay in the fuse box (of the same type)

    Hope this helps...
