A while back the window switches in the drivers door stopped working. I bought some new switches and swapped them oer today and still having the same problem. The electric wing mirrors work on both switches but none of the windows will open or shut via the drivers door and because i put the window lock on the back eindows, they are now stuck closed. All the other switches work (when the lock isn't on the back windows of course). The fault was intermittent but now it's constant. Any ideas please??
