Before I start, let me say this. Princess Auto is your friend. If anyone here is from Canada then you probably know what Princess Auto is. Everything used in this guide may be purchased at Princess auto with the exception of the heating elements which I got from Canadian Tire.
***DISCONNECT YOUR BATTERY!!!***
***ATTEMPT AT YOUR OWN RISK!!!***
***I TAKE NO FAULT FOR YOUR F**K UPS!!!***
These are the heating elements. They are Kimpex Heat Grip Kits for motorcycles. I purchased 2 kits at $30 each. Each kit contains 2 elements. You could do this mod with one kit if you wanted but the mirrors are large enough to accommodate 2 elements each.
This is one of the elements out of the package. They are a peel and stick affair.
Remove the inner door trim.
Unplug the power mirror. There is a little clip holding the wire just inside the door. Pull it free.
I forgot to take a pic of removing the mirror glass. I'll add one tomorrow. After the glass is removed unbolt the mirror assembly from the door. There are 4 bolts. The window must be rolled down to do this. Then simply pull the mirror off the door.
Remove the 4 screws holding the mirror motor, unplug it and remove it.
Remove the 4 screws holding the mirror arm and remove the top cover.
Remove the smaller of the 2 covers on the arm. Take your time and don't break any clips. Then cut 2 lengths of wire about 3 feet long each and insert them through the arm the same as the motor wires.
The motor wire has a large rubber seal around it where it attaches to the door. Don't bother trying to squeeze the 2 wires through with the motor wires, you'll probably just wreck the wires. Instead, poke a hole in the rubber and feed the wires through that way.
Reinstall the mirror assembly to the door. Remember to make sure that seal is in properly. Feed the wires through with the motor wires. You will need to run one wire into the engine bay. I'm not going to suggest a method for this as everyone will have their own idea I'm sure. I will recommend using a fuse for each mirror. You could use the ground wire from the wiring harness for the door. I just grounded directly to the door.
I used 1/4" wire loom around all my wires and ran them along the wall over to the fuse box. This is for both sides.
