Hi all ! have asked this question before but no response,hope someone can help this time. My XJR has powerfold wing mirrors, they work fine until you try to put them back to normal and then the passenger one almost folds 180 degrees. I am quite happy repairing or replacing the faulty one but i have no idea how to access or remove it .I presume there must be some sort of microswitch/stop that is broken. Obviously dont want to damage it ,so any suggestions would be much appreciated. many thanks...
