Upgrade to power folding mirrors, Extra wiring necessary? Options

[quick_5hifter]

Problem #1:
My car has electrically adjustable heated mirrors.
I've just purchased a set of used power folding mirrors, also electrically adjustable, but they are not heated.
I've removed my old mirrors a few times, so I remember that the main plugs are (probably) the same as the "new" power folding mirrors.
The question is: do I have to add any extra wires to the installation, for the "new" mirrors to power fold?
I also have the door control panel that contains the power folding operation button.
If it makes any difference, my car is an european hatchback ST202 made in 1995 and it has also:
-power windows and sunroof;
-power lock;
-power antenna;
-A/C (not climate control).
I didn't replace the mirrors yet, because I would like to know if I have to modify wiring first, so I don't have to work 2/3 times.

Problem #2 (must read Problem #1 first):
One of my heated mirrors' glass is broken and I've managed to recover the heating installation (that plastic thing with the copper "maze" on the mirror's back); can I just glue the "heater" to another glass, in order to make it heated? If it's a "YES", what kind of glue should I use?

Problem #3:
The power folding mirrors that I've purchased seem to have a little problem (the seller told me that): the left mirror needs a little "mechanical" help to fold itself, but it unfolds perfectly; could this problem be solved by an electrician?

Thank you very much for answers to any of my questions! And please excuse my bad english!

(Edit: as I always do before creating a new topic, I used the search function and I didn't find anything to solve my problems.)
