MonteCarlo 2000




The W-Body rearview mirror snaps onto a small metal tab called the rearview mirror support. The rearview mirror is removed from the support by prying with a small flat-bladed tool. There is also a small wiring connector, under a cover, if it is a lighted rearview mirror.

The rearview mirror is attached to a rearview mirror support which is bonded to the windshield. The support is installed using a plastic-polyvinyl butyl adhesive. To install a detached mirror support or install a new part, the following items are needed.

Loctite® Minute-Bond Adhesive 312 two component pack, GM part number #1052369, or equivalent.
The original rearview mirror support (properly prepared, see below) or a replacement rearview mirror support.
Wax marking pencil or crayon.
Isopropyl alcohol.
Clean paper towel.
Fine grit emery cloth or sandpaper (320 or 360)

The following procedure calls for layout lines on the windshield. Make all marks on the outside of the windshield. This keeps the inside of the glass clean of wax marking pencil marks. Simply look through the windshield from the inside when positioning the mirror support, lining up the layout marks on the outside of the glass.

  3. Measure and find the center of the windshield and draw a line.
  5. Position the support centered on the center line and with the top of the support aligned under the horizontal line.

  17. Wipe the sanded rearview mirror support with a clean paper towel saturated with isopropyl alcohol and allow to dry.
  19. Follow the directions on the manufacturer's kit to prepare the rearview mirror support prior to installation on the windshield.
