they dont kiss in any of the episodes
Miroku and Sango don't kiss in any episodes....SO far, maybe in InuYasha! Kanketsu-hen. But they do kiss in the manga. Miroku was in a matter of life and death, and Sango kissed him, whereas InuYasha and Kagome kissed in InuYasha movie 2: The castle beyond the looking glass
I think there are a couple, but the best one is Inuyasha: The Final Act episode 18
Yes they kiss.
Episode 18 of InuYasha the final Act
Inuyasha and Kagome kiss in episode of Inuyasha Kanketsu hen (the final act) They also kiss in the second movie, Inuyasha the movie: Castle Beyond the Looking Glass. They almost kiss in episode 18 of Inuyasha Kanketsu hen and they almost kiss in ep 14 (not kanketsu hen)
well....there's episode 135 when sango was drunk and tried to kiss inuyasha. so she told him to sit out of jealously......LOL, like sango w/ miroku! :) and also in movie 1-he didn't appreciate her home cooking and said that all he wanted/needed was ramen
on episode 23
Yes, in the final episode of InuYasha: The Final Act, Miroku is actually on his way back home to Sango who is, at the time, giving birth to their third child. They are happily married with a set of twin girls, and a new baby boy. Miroku's Wind Tunnel no longer exists, so Sango and Miroku can carry out happy lives together.

he doesnt kiss her in her room
The manga they kiss in is InuYasha. Regarding the chapter they kiss in, it is chapter 523 page 11. (The page is right below this... it's a related link.)
Sango never actually 'looses her mind'. she gets completely distraught during episode 50, that unforgettable face, over her brother Kohaku and almost commits homicide/suicide over him, then in 100, fight in the forest of despair, where she was in the coccoon of the moth demon, and saw an illusion of kohaku killing her friends (not real!). Finally, sango gets drunk on the mist of sages, as it is what appears to be sake in gas form. She then attempts to kiss InuYasha, and leave the others behind, then finnaly beat the snot out of miroku in episode 135, the last banquet of miroku's master.
