Hi, I noticed that my passenger side folding mirror is jerky and makes a clicking and sometimes a squeaking noise when i lock and unlock the car. Is it possible to lubricate the mechanism to make it move freely please? If so, should I use WD40? There is a lot of dust in the air where we are at the moment. could it need dismantling and cleaning perhaps? I need to get it sorted quickly as doing a 1000Km journey in a couple of days. Should I perhaps take it to my local dealer? Thanks for any advice.
