I would try swapping the fuse box as you have one - ten minute job.
Check the fan isn't seized by spinning it round.
If the blowers fail on all 3 speeds, it's usually the fusebox. I just fixed my birds mk5 with the same problem, took the fusebox out and resoldered any dodgy looking connections. I did find one bad looking one and I reckon that was it.
If the fans fail on 1 & 2 then it's the resistor pack on the fan thats gone.
