Fabia vRS wing mirror adjustment

My wing mirror adjustment and heated mirrors wont work, 

They look like that have been changed for black ones (red car)

Had the door card off an everything looks connected apart from door speaker which is missing

Cant see any obvious snaps in the wire also where the door loom goes through the shell into the car, cant see any damage there.

Haven't checked the passenger door yet

Is there anything else i can try before i pull the other door card off? 

Any particular place to look for problems?

Thanks
