2013 ml 350 bluetec liftgate
my battery (both of them) went completely dead.. After both were replaced, my liftgate would not open with my remote or by using the latch on driver's side door. A local mechanic that i use said to replace the liftgate control module.. Done. But door still wont open .. I can open it manually. Does anyone know if this has something to do with my dead battery? Like, i had i to "re-train" the windows so they would power up with one touch.. Just curious.
Thanks.
