2007 b7 electric windows not working
 

Hi all I have a problem with with all my electric windows not working. They were intermittent for a week or so then stopped altogether. They do not work off any switch or by holding the key in the door. I have checked fuses & the ccm is dry. Electric mirrors, central locking & interior lights are all working. Is there anything else apart from a faulty ccm which would cause them all to go off? Any help would be greatly appreciated 😢
