I'm afraid it didn't make sence grammatically and literally. It would be wrote as "あなたの心はどこにありますか", as masaya said. You wrote "heart" without any article; I am guessing that you meant it concerning human feeling, emotion or ethics not human organ; speak with caution, it sounds somewhat offensive.

What do you mean in English? If you mean "You have no heart." by saying "Where is your heart?", 「あなたの心はどこですか etc. 」may not be enough.

Sorry, doesn't make sense. Maybe you should write : あなたの心はどこですか or あなたの心はどこにありますか どこにあなたの心はありますか etc Perfect translation is hard but my word order must be correct. If the heart means the organ in the chest, it called 心臓. If it means feelings, it's 心

I found one example in my dictionary. It says “Where is your heart?” means 優しい心はどこに行ったの、冷たいね。So you could also say (あなたの)優しい気持ちはどうしたんですか。(あなたの) 優しい心はどこに行ったんですか。

In English should be Where you are mind (exist) ?( Heart sometime use as mind but this case not fit for the sentence ) mind (mental reaction ) should be used I think you want say " what do you think about somebody. This sound like a Japanese English.
