after making sure your fuses are ok, go in the trunk and behind the access cover where the battery is located. above the battery should be a fuse panel, which may be hidden under the insulation trim, there should be some fuses and relays there. the relay closest to the rear of the car is probably the relay you are looking for. you can try swapping it with another relay in the panel if the relays are the same. bmw always puts a part number on their relays. i would start with checking the fuses and relay first.

I had the same problem. I thought it was an issue with a blown fuse, but also noticed that the rear wiper was very stiff.
I solved it by opening the rear window (so the wiper is not clicked into the motor) then squirt some WD40 into the wiper mechanism (I put the oil in from the outside). Gently move the wiper from side to side until it starts to free up - after a couple of movements the wiper should be moving freely again. No issues since.
At the same time, check that the washer jet is correctly angled. Mine was squirting directly into the wiper which may have caused it to rust up a bit.
