Having a spot of agro with my door mirror adjuster. Didn't work so gave it a good squirt of Servisol (contact cleaner and lubricant) which has restored up and down movement a bit but done nothing for left/right.
Looks like the switch would come apart by depressing 4 small lugs.
Anyone had one apart - and put it back together!

Not had one of these apart, but shouldn't be too tricky.
Just be sure that you don't lose any small contact plates or springs.

Thankfully 80s / 90s technology is quite simple and crude to work on.

If the switch continues to refuse to work, try checking any soldered connections.

I had my Astra mirror switch apart which got broke in the process! Looked like the joystick button was ultrasonically welded in after the case was assembled.
Anyway nothing to loose I set to it with a small watchmaker screwdriver and as soon as the case was parting company I had loose bits inside! Came apart ok and I could see immediately where the bits came from and decided they would be able to be reassembled.
Contact areas were green with verdigris. Plain copper contacts with silver plated cones that are moved by the joystick. It all cleaned up ok with very fine scotchbrite and debris flushed away with contact cleaner, tiny spot of synthetic oil on the joystick spring loaded plungers and it all went back together well and it feels much nicer.
Fit back tomorrow and feel sure it should be all good!
Probably have my fingers crossed just in case though!
Took a photo but not very good at that bit!
