replace the mirror glass...the copper heating elements in the heated mirrors have a tendency to get too warm, and melt themselves to the plastic backing plate of the mirror...have seen it on numerous tahoes and escalades. new heated power mirror should only be about 44.50 from your dealership, if you have power/heated/auto dimming, the dealership is going to quote you 302.90! search around on ebay, look for escalade mirrors of the same year and tahoe/suburban/1500 pickups of similar year range mirrors. very easy to fix, look around on this FAQ and you will find where I posted a how-to in response to a question about replacing the mirror on a 2002 i think it was.
Rastar image.
It gets blurry and smaller
Put your graphics on lowest setting.
A plane mirror forms an erect, virtual image of the same size as the object. As a person gets closer to a plane mirror, the image gets larger.
it is because of the differences between the mirror's temperature and the air's temperature.
no it doesnt it gets smaller
When light shines onto an object viewed in a mirror, the rays are reflected into the eye. The rays come from a position behind the mirror. The image is the sane size as the object and the same distance from the mirror. In the image, left is right and right becomes left. The angle that the light gets pointed on to the mirror is the same as the angle that gets reflected of the mirror!
there is an imaginary point in front of the concave mirror, called the focal point or focus, which is half the length of the radius of the sphere of which the mirror was a part of(radius of curvature). usually an object if seen in between the mirror and focus gets magnified, beyond the focus, it gets inverted and reduced.
Water can get in when the firewall flashing is missing outside under the windshield cowling. The water gets into the heater/defroster system and then drains on to the floor.
Exhaledair contains water vapor. It gets condensed on the mirror making your image look hazy.
it doesnt fly
You need check it. Very often it gets scratched and as a result damaged. If it's damaged even in one place it will not work. If it's the case you can repair it using a special defroster repair kit which you can get from Advance Auto parts. Check the fuse too.
