- Determine the location of the mirror mounting base by marking the outside of the windshield with a marking pencil where the base was previously located. If it is not clear where the base was mounted, use the following steps to determine where the base should be installed: Using a measuring tape, measure the distance between the windshield pillars from the base of the shade line . Using a marking pencil, halfway between the windshield pillars, draw a centerline (1) on the windshield from the roof panel to the windshield base. Draw a perpendicular line intersecting the centerline (2) at that location. The top center of the mirror mounting base will be at the intersection of these lines.
- Scrape the inside windshield thoroughly with a safety razor or utility knife in order to remove all old adhesive.
- If reinstalling the original mounting base, place the mirror mounting base in a suitable holding device, such as a vise.
- Clean the mirror mounting base thoroughly with a safety razor or utility knife in order to remove all old adhesive.
- Clean the inside windshield and the mounting surface of the mirror mounting base thoroughly with a clean cloth saturated with naphtha or a 50/50 mixture (by volume) of clean water and isopropyl alcohol.
- Use Inside Mirror Adhesive Kit GM P/N 89021329 (Canadian P/N 993362), or equivalent, to apply a small amount of activator to the mounting surface of the mirror mounting base.
- Apply a small amount of activator to the windshield where the mounting base is to be installed.
- Allow the activator to dry 5 minutes.
- Apply 1 drop of adhesive to the center of the mirror mounting base.
- Immediately apply the mounting base to the windshield, ensuring that the mounting base aligns correctly to the marks made on the outside of the windshield.
- Hold the mounting base firmly in place for 1 minute.
- Allow the adhesive to set for 15 minutes.
- Install the mirror to the mirror mounting base and fasten, if necessary.
- Connect the electrical connector and install the wire cover, if equipped.
The power mirror system consists of the following components
- Outside rearview mirror switch
- Mirror selector switch
- Driver outside rearview mirror
- Passenger outside rearview mirror
- CIG Fuse 15A
Each of the outside rearview mirrors contains two motors. The vertical motor operates the mirror in the up and down directions, and the horizontal motor operates the mirror in the left and right directions. Each of the outside rearview mirror motors are circuit breaker protected.
The outside rearview mirror switch is a 4 position directional switch (Up, Down, Left and Right).
The mirror select switch is a 3 position switch (L, Off and R).
The mirror direction switch is a 4 position switch that allows the operator to move the selected mirror up, down, left or right.
The outside rearview mirror switch receives power through the battery positive voltage circuit from the 15A CIG Fuse. The power mirror switch also receives a constant ground.
The four positions of the direction switch have dual switch contacts. Each of the contacts are connected to opposing sides of the appropriate power mirror motors through the selector switch. The selector switch completes these circuits depending on the position of the selector switch (L or R).
If the selector switch is placed in the L position and the up switch is depressed, battery positive voltage will be supplied to the left outside rearview mirror vertical motor through the left mirror motor down control circuit and ground through the left mirror motor left control circuit. If the down switch is depressed, battery positive voltage will be supplied to the left outside rearview mirror vertical motor through the left mirror motor left control circuit and ground through the left mirror motor down control circuit.
The remainder of the mirror functions operate in the same manner as described above. Placing the power mirror switch in opposing positions, left/right or up/down, will reverse the polarity to the mirror motor.
