wing mirror-very loud click on folding it in/out
 

hello got a 2004 e53 Passenger side wing mirror housing makes a very loud click when I push it inwards towards car and also when I fold it back out (alas have to do this as car is parked near a school with sidewalk that barely fits a fit through and you know school kids pushing each other around and one car etc ), the wing mirror is actually electric but the housing is not, so far have not had any issues but the click is very loud and not a smooth action like the drivers side,, anyone had this issue before?
