It would seem both the window regulator and folding mirror are working OK in themselves but cannot operate independently for some reason. It looks as if there is insufficient voltage going to the door to operate both. That could be because of a poor voltage supply or poor earth. Has the connector plug at the door hinge been checked for corrosion or water ingress. Also fitting a temporary earth to both units may be worth trying - if only to narrow the field of search.
