Did you bypass the relay, to see if the blower motor would run?
I don't know what tests you've done? The red wire at the relay, should be hot all the time. The purple wire carries voltage to the fan. If you use a jumper wire between those two circuits, the fan should run. You may need to use an inline fuse in the jumper, just to be safe.
According to my info, with the relay energized, only the high speed circuit has continuity to the blower motor.
When you check fuses, you also need to check that one of the terminals is hot, where the fuse plugs-in. Some circuits are hot all the time, some go hot when you turn on the key.
