300G mirror project

["skyhawk" <skyhawk@xxxx>]

Dear Membership,
I received a lot of information from various members in response to my question about 300G remote mirror disassembly techniques. Following their instructions, and figuring out some of the methods myself, I was able to get the thing apart. Here's how to do it:

1. Remove the lower-dash plastic joystick bezel (the one that says 'mirror control') by prying it out of the housing..this exposes the spanner nut so that the joystick unit can be removed Loosen this nut, remove joystick from dash mounted pod.
2. On original and untouched units, you will see three wires attached to the joystick. There may be a rubber band surrounding them..sometimes it is gone. The three wire ends are color coded...make note of what goes where. If color code is gone, use three new color dabs so that re-assembly won't result in a mirror that does the opposite of what you tell it to do! Using a pair of needle-nosed pliers, carefully pull the wirecoil sheath away from the housing and remove the single strand of wire from its slot with its stub end intact. Do this for each of the three wires.
3. Under the hood, carefully pry from the firewall the three-wire grommet through which the cables run. Once removed, you will have three cables covered by a plastic sheath with a rubber grommet attached. 
4. Use dishwashing detergent to lube the grommet area where the cables come 
through. Pull each cable through the grommet...one at a time. It will take a hefty tug. Remove the plastic sheath from the cables
5. Remove the screws holding the mirror assembly to the fender...Pull the cables 
through the fender and remove mirror assembly from the car. Tape the edges of the hole to prevent scratches.
6. Remove the big mirror adjustment screw, and the two small screws at the bottom 
of the mirror housing. Pull the cables through the center post one at a time.
7. You now should have 4 pieces...1)the base and outside posts cast as one unit, 
2) the center post through which the cables run 3) a bullet shaped adjustment 
adapter, and 4) the mirror housing with its wires and glass still attached
8. Upon examining the inside of the mirror housing, you'll see a spring and three 
wires attached to the rear of the glass. It looks like the retainer inside the mirror 
housing with its 3 wires and spring is cast as one unit with the mirror 
housing, which makes it appear the glass is non- removable, but the retainer is 
actually pressed into the housing. Place the housing face down on a firm 
surface . Take note of the color coding of the three cables as to which one aligns 
with the PDDC logo on the back of the mirror housing. Insert the end of a narrow 
punch into the hole in the back of the mirror housing through which the cables 
run, until it contacts the retainer. Using a small hammer, give it one or two sharp 
raps, and the retainer with its wires, spring, and glass should separate from the 
mirror housing.

Thanks to all of you who responded......Hope these tips save you some time and effort along the way!!
