Rear wiper and washer not working

[Jim666]

Have checked fuses all ok but no pos feed down to washer motor 

is this likely to be the switch 

it will very intermittently operate if switch is left on

Hi Jim

The switch should be easy enough to check with a multi meter, same with the loom to the washer motor. Check the earth connections carefully BMW use a lot of common earth points which are often at the bottom of the problems.
