Jayemtee is spot on- it's quite the sticky wicket. Here's the procedure that I followed in order to access the connector and bulb:
1) Remove the power mirror holder, and the mirror housing.
2) Carefully push on the top edge of the mirror holder by hand.

**Carefully push on the top edge of the mirror holder (A) by hand and detach the bottom hooks (B)**
3) Put a shop towel in the opening between the lower edge of the mirror holder and the mirror housing to prevent scratches, and detach the bottom hooks with a flat-tip screwdriver wrapped with protective tape.
4) Separate the mirror holder from the actuator by releasing the hooks. If equipped, disconnect the mirror defogger connectors.
5) If necessary, remove the mirror housing.
6) Remove the screws.
7) Release the hooks, then remove the visor and the mirror housing.
Disconnect the 2P connector from the side turn signal light.

You should be able to access the bulb now. Be careful when you're handling it though, as it is quite fragile!
