Passenger Rear View Mirror Not Adjusting

[RossoDiamante]

Have a passenger rear view mirror that doesn't adjust properly. It wiggles a little when I move the adjustment stick. But nothing coordinated or in relation to the direction of the movement of the control stick. It always defaults to the up and out position giving me a great view of the western sky. Is there anything repairable in there or do I need to be looking to replace it? If so, stock vs. aftermarket options?

Thanks,

Brilliant! I'll have to see where would make sense. I am the only one that drives the car. Only one in the family who will touch a manual transmission!

I don't know that I'd mind the vibration. But I would like a view of something other than the tree-tops alongside the highway a quarter mile behind me!

Does "door card" equate to the inner shell, fabric-covered lining? Is it tethered in by everything like the window crank and door opener/release?
