The rear wiper relay on earlier fuseboxes sits behind the glovebox. (if
I remember correctly)
According wiring diagram, it´s fused via F14 with a black/yellow wire.

There is also an inline connection, from relay to up the A-pillar.
Disconnect, and on the half to the A-pillar, connect one of the wires
(try/error) to +12V and the wiper should start spinning.
