How do you replace sideview mirror on 1992 Chevy astro van?
If you are just replacing the broken glass on the Chevy astro
van it is simple. Well, you first must breakdown the mirror from
the plate called a frame. One simple way to do this is to get a
flat strong instrument like a wide screw driver or scraper. Now to
loosen the adhesive from the plate you must apply some heat.
Ideally a propane torch is good, but if you have the wife's
hairdryer or a heat gun that will also work. Heat up the mirror
enough so you can get the screwdriver or the scraper under the
mirror and pull all the broken pieces off. Make sure you are
wearing gloves and protective eyewear, and after the side view
mirror glass is removed, make sure all the mirror and adhesive is
clean off the framed plate.
Now you need to get a glass only product. I have purchased them
at this website
Once you have removed your side view mirror from the frame, you
now need to , apply a non latex based silicone glue to the black
frame. Apply the glue outward so it extends past the lip of the
frame. I call this the snow cone effect. Glue it in 5 spots. One in
the middle and 4 in the middle corners. Don't get too close to the
frames edge, as it will ooze out of the frame, making a mess. So
use small dabs of the adhesive 3/8" inch wide by 1/2" outwards.
Once you have adhered the mirror to the plate, get some easily
removable tape, like masking tape, and tape the mirror around the
mirror housing so that the mirror will not slide off the frame.
This will also allow you to drive without the mirror falling out.
Keep the tape on for 24 hours for cold climates and 5 hours in warm
until the glue dries. Then remove the tape and your are done. This
project is easy, and can be performed on many cars, trucks, and
vans, not just the Chevy Astro
