My outdoor mirror glass is somehow loose. It sits indissolubly firmly in the mirror, but wobbles in all directions, especially on the highway by wind pressure the glass always adjusts. Adjust ( automatically by mini joystick) the mirror can only be adjusted in three directions: up, down and away from the car (so the view away from the car) The motor works towards the car, but the glass does not move. I always stuff a small piece of wood (stock, splitter whatever… ) between is a) very annoying and b) dangerous on the highway… Can I do something or how do I take out the mirror glass and look at the adjusting unit? (is a heatable mirror by the way)
