There are screw covers on the rear-view mirror housing. Pop these covers off with a thin and flat tool, then tighten the screws that hold the housing to the car.
To tighten a passenger mirror on a 1990 Cadillac Brougham where the head spins on the stem, first, locate the adjustment screw or nut that secures the mirror to the stem. If the screw is accessible, use a screwdriver or wrench to tighten it gently until the mirror is secure. If the screw is not easily reached, you may need to remove the mirror from the vehicle to access it properly. Ensure not to overtighten, as this can damage the mirror or the stem.
under cover!If you are talking about the outside mirrors, there is a plastic/rubber triangle at the front of the window that pops off and then there are several small nuts that come off the release mirror. If it is heated then there will be wiring to unplug. Replacement procedures will be obviuos once that plate/cover is off.
