rear wiper not working

[no2lurch]

on my e30 touring the rear wiper dont work.

the light comes on with the switch but the wiper dont move. the washer jet works thoguh.

anything to look out for? the connectors on the plug seem to look fine and clean.

see if its getting power with a test light and if so it must be the motor itself so open it up and check that its not rusted and give a good clean with some sandpaper and put a drop of grease in it
