i have a centre console arm rest that doesn't always lock down, sometimes it opens straight away which has left me thinking
if i've pressed the arm rest down far enough but today i noticed that the latch hasn't been returning to the locked position as quickly
as it should,luckily it is an easy fix.
1) open arm rest and remove 2 cross head screws
2) unclip the plastic undertray down the sides until there is just enough room to unclip and remove the lock assembly
3) on one side of the lock there is a plastic hook attached to the release button (stops the button coming out too far) gently lift it to release the two halves
4) once seperated give both halves a good clean,you will find some heavy grease around the spring and runners
5) i then used a ptfe spray on both halves and re-assembled
jobs done
i have seen on other sites that owners have gone back under warranty for this but its not worth the time and effort its a 10 minute job to do.
