got a ST170 and was using Forscan and its had errors in there from ages ago, all got deleted at a garage but forscan has obviously kept them, most have been removed but im stumped on 2 that wont delete

Code B2256 - Heated Windscreen relay short to ground Heated window seems to be working perfectly but is this a warning its about to go wrong ?

Also have a Code B1550 - Global closing window motor circuit short to ground, I dont have global closing as only got a 3 door (Wish I did have it though) I did break the window regulator at the weekend by forcing the window down when it was frozen over, could this cause that ? haven't changed it yet as havent found a replacement locally.
