Folding Mirrors
 

My folding mirrors have suddenly stopped folding.

All other functions work fine.

Any ideas on this?

Thanks

My folding mirrors work when they want to.
The passenger side rarely works - drivers side is much more likely to work.

They stopped working after I stopped folding them as much - living in a very dusty environment, I expect that they are so full of dust which why not working.
The drivers side works a lot better now - I did have to lightly encourage it a couple of times though.

I expect once cleaned and re greased all should be 100% fine for both sides
