The Lubavitcher Rebbe did not "pasken" (make halachic rulings), nor have a publicly announced position on ascending Har HaBayit (the Temple Mount). However, many years ago Rabbi Yitzchack Ginsburg and Rabbi Moshe Schloss (two Chabad rabbis) were going up onto Har HaBayit.
Reb Moshe Weber, obm, wrote the Rebbe and asked if it was alright. The Rebbe wrote back that under no circumstances should anyone go up onto Har Habayit. (A contact for a copy of the letter is available.) Reb Edo told me that Reb Moshe told him it was one of the most severe sins to go up.
Akiva adds: Clearly halachic opinions regarding ascending Har HaBayit differ greatly (with the majority prohibiting it). One is strongly advised to consult one's rabbi, rosh yeshiva, Rebbe, or halachic authority prior to deciding to ascend.
