i see that door, just no physically way of getting to it... maybe i'm looking at it wrong
there's 2 green doors, one to the west (just been there, last quest part) - one to the east.
red door where the quest indicator is in the south
north - the airlock to go back to the ship.
the 2 paths around to the east are blocked, (the other route where tavik is) and no console beside either (that work). there's some stairs down heading east but not stairs up.

sorry but your directions don't help, Bioware SHOULD be fixing bugs but they aren't (small minor ones like the trooper not having the item quest (where you learn about adding stuff onto weapons and recieve a free mod thing), too the sith warrior whose quests never give them 8 commendations, only 6 even picking up from mobs, to the fact that the first costumes for characters; bounty hunter/imperial agent and smuggler still are mixed up with a couple of options)
these are just from the top of my head.
