The wife managed to catch the passenger size wing mirror - the wing mirror itself is generally undamaged however now will not open/close. It also appears that using the internal switch to open/close the wing mirrors no longer works.

 

When turning on the ignition, the drive side mirror does open, whilst the passenger side mirror (which was broken) does not open however you can hear the opening mechanism working/turning without success.

 

From the looks of it (photo attached) it looks like the bearings in the base of the wing mirror have snapped/become broken. Any suggestions on how best to fix? Will i need a completely new wing mirror or is it possible to simply remove and replace the apparent metal bearings to fix the issue?

I would say personally that is a complete new mirror. 

 

Some little twerps decided to kick my passenger side mirror off a couple of years back which broke in the same place as yours.

 

After a trying many things to repair it, the mirror mechanism wasn't 100% operational and the mirror casing and positioning was still out.

 

It was fairly simple and inexpensive tracking down a complete mirror unit online from scrapper/ brakers on eBay, Parts Shark and other similar sites. I couldn't find the correct colour however, so had to re-fit my original case which was simple enough thankfully. 

 

The new unit is easy to fit if a little time fiddly as you have to take off the door card before uncovering the nuts that hold it in place, but once it is done should work as well as the original one. 

 

Good luck with it 🤞🏼
