On most vehicles covered by this guide, the rear view mirror is attached to a support which is bonded to the windshield glass. If so mounted, the mirror is usually slipped in place over the mount, then secured using a small hex head set screw.
On some vehicles equipped with mirror mounted map lights, the mirror may be attached to a support at the windshield moulding.
- If the mirror is mounted on the upper windshield moulding, remove the retaining screws. If equipped with a map light, pull the mirror downward and disconnect the light electrical connector. Remove the mirror.
- If the mirror is attached to the windshield, remove the mounting set screw and remove the mirror from the vehicle.
- If the windshield is being replaced on windshield mounted mirrors, measure the support location in from points around the windshield, these measurements will be used during installation to assure proper positioning of the support.
- If the support has come off the windshield, as is often the case on older vehicles, see if there is a spot of old adhesive remaining. If so, the location should be marked or measured to assure proper installation.
The mirror support is usually installed using a plastic-polyvinyl butyl adhesive. Service replacement windshields often come with the mirror support bonded to the glass assembly. To install a detached mirror support or install a new part, the following items are needed:
- Determine the rear view mirror support position on the windshield. Support is to be located at the center of the glass, slightly below the top of the windshield.
- Mark the location on the outside of the glass with wax pencil or crayon. Also make a larger diameter circle around the mirror support circle on the outside of the glass surface.
- On the inside of the glass surface, clean the large circle with a paper towel and domestic scouring cleanser, glass cleaning solution or polishing compound. Rub until the area is completely clean and dry. When dry, clean the area with an alcohol saturated paper towel to remove any traces of scouring powder of cleaning solution from this area.
- With a piece of fine grit (No. 320 or No. 360) emery cloth or sandpaper, sand the bonding surface of the new rear view mirror support or factory installed support. If original rear view mirror support is to be reused, all traces of the factory installed adhesive must be removed prior to reinstallation.
- Wipe the sanded mirror support with a clean paper towel saturated with alcohol and allow it to dry.
- Follow the directions on the manufacturer's kit to prepare the rear view mirror support prior to installation on the glass.
- Properly position the support to its premarked location, with rounded end pointed upward, press the support against the glass for 30-60 seconds, exerting steady pressure against the glass. After five minutes, any excess adhesive may be removed with an alcohol moistened paper towel or glass cleaning solution.
- Install and secure the mirror.
