    1994 Buick Roadmaster won't divert heat to defroster or floor

    There is a vacuum line that's plastic on the passenger side back near the firewall. Sometime they have a little black ball looking thing (vacuum canister) that the vacuum line hooks to. Look for vacuum leaks in that area. That will cause the problem you described.
