Bug Skyrim

Bugs
Esbern will fail to come out of his room. This can sometimes be remedied by spamming the "E" key, or you may use the dev console "TCL" command to disable collision. Esbern does not speak, this can be fixed by extracting the voice files.
If this doesn't work try using the TCL command to walk trough the door. Shut down the TCL, talk to him, when he starts using the chest kill him. Then you can talk to him again and tell him to lead the way.
After you talk to him, type setstage MQ202 160 and setstage MQ202 170, it'll open the door and make him talkative again
Sometimes this quest will fail to start at all and never even show up in your quest log after completing Diplomatic Immunity, in which case you will have to skip ahead to the next quest, Alduin's Wall. In the dev console, type setstage mq203 5.
Tips
If he ever gets stuck again just kill him.
If killing doesn't work try failing to pickpocket/place an item.
When you get outside he is just as a regular companion.
Follow this link and do as the OP says http://www.minecraftforum.net/topic/786124-skyrim-a-cornered-rat-bug-fix/
Tlc didnt work .. he just closes the window anyhow
"FO3 Archive Utility" seems to work best. Download that from

http://www.fallout3nexus.com/downloads/file.php?id=34 file>open>find your skyrim data folder, pick voicesextra.bsa, extract all to your desktop, move it back to your data folder. You could also try the console command "setstage mq203 1" to skip the quest, but this does not solve the voice issues.
