W211 (2009) Electrically folding wing mirror issue Both mirrors fold in perfectly, no problem at all. The NS mirror folds out fine but the OS mirror is stiff. It tries and gets about half way before giving up. To get it to fold out all the way it needs a gentle push at the same time as the motor is working. In effect I'm giving the motor a helping hand. Hoping it's just dried out stiff pivot points or hinges but grateful for any hints tips before I start pulling it apart.
