How do I replace the drivers side mirror assembly?

If the signal flashes on the outside of the glass, then the yellow lens will pop off the mirror assembly using a small screwdriver etc for bulb access. If the signal flashes inside the mirror assembly, the mirror will need replacement or there is a wiring issue

To replace your side mirror, disconnect the battery's negative cable. Take off the interior door panel. Unplug the wiring harness if you have power-controlled mirrors. Take out the mirror bolts with either a socket wrench or a nut driver. Separate the actual mirror from the mirror assembly. Use a torx driver to extract the screws, and then pry the plastic tabs on the backing until the two pieces separate. Attach the new mirror to the assembly by snapping it onto the backing with the tabs.-----------------------------------------------------------------------------------------

If it's just that the bulbs that have burnt out you'll need to position the exterior mirror glass inward toward the vehicle.(Note: Use caution to not trap the side lamp assembly wiring during installation, or damage to the wiring may occur.) Using a flat blade screwdriver or something similar, push the mirror side lamp assembly forward while releasing the retaining clip. Separate the bulb holders from the mirror side lamp assembly and remove the side lamp. Replace the bulbs and reassemble. I hope this helps you out.
