Use the flat side of a metal spudger to peel the black rubber cover off of the casing.
Use some force; the rubber cover is securely attached to the housing.
Rotate the casing until it fits onto the housing with no gaps between it and the clear cover.
Make sure the casing is properly oriented onto the housing. Orientation is important here.

Place the driver flat on a table before completely separating the two halves of the housing so components of the drill don't fall out during opening.
Pry apart the two halves of the housing at the back side of the driver using the metal spudger. The housing is easier to remove if you pry from both sides.

Lift out the motor.
Follow the wires.
The circuit board located nearest the battery pack and the LED light will be hard to pull out.
Remember to precisely place all components in their correct slots with their correct orientations when reassembling.

DO NOT attempt to desolder the white shrink wrapped wire located at the bottom left of the trigger assembly. It requires advanced soldering techniques and isn't necessary.
The soldering iron is hot and could burn you.
Take note of where each wire is attached to the trigger assembly for resoldering the new trigger.
Use the soldering iron to desolder and remove the red, blue, and three black wires.
If you don't know how to desolder, or need to brush up on your skills, iFixit posted a How To Solder and Desolder Connections guide.

The following steps are for your new trigger assembly.
Be careful not to cut the wire while stripping the insulation off.
Using 16 gauge wire strippers, strip about one quarter inch off both the white wire of your new trigger assembly, and the white wire coming out of the translucent orange fuse.
