Hi guys. can you help me with F/D?

I never used it, always landed visually, but wanted to learn how to use it. I can fly using F/D in HDG and VOR modes, Alt holding works fine too, but i cant use it for performing ILS approach. NAV/LOC, Appr Auto/man - it seems to me that they doesnt work. Turning that modes on disables glideslope indicator, and F/D itself going nuts, it shows far to the side, and not responds to anything. Im talking about hand flown landings.

Was anyone able to use it in this modes, or it doent work?

same question for 727, 737 F/D ?
