Fan Relay good, Fuses good, Looking into deeper under the dash stuff.

Fan will not blow, rear defog will not work, temp control won't work. We straight wired the blower fan from relay and it worked and also put voltage to relay and it works. For some reason, fan relay is not getting current. We're lost.
