Hi all 

I've got a bmw 1 series 116i msport 2014 

I was moving the passenger wing mirror an it just stopped working now I carnt use any windows or wing mirrors on the drivers side main switch 

I've bought a new switch an that doesn't work I've checked fuse with a multi meter an all fine 

Any ideas 

Thanks simon 

Check for continuity between the live at the switch and the fuse. Check the earth from the switch to the main body. 
you should have 12 v at the switch plug with the engine running. 
The wiring loom runs through the door near the hinges and can sometimes become brittle. 
if there is no power at the switch, make a + and - wire from a 12v battery to the switch terminals and see if the switch works. That will confirm the loom issue.
