Self-consistent calculations are made of wave functions and two kinds of Hall resistance for a 2DEG confined in a uniform ballistic quantum wire in a weak perpendicular magnetic field when several subbands are occupied. We find intermittent quenching of the Hall resistance associated with the local chemical potential as the electron density varies. The quenching is due to the overlap of opposite-going wave functions in the same subband, which is enhanced significantly by the singularity of the density of states at the subband minimum as well as by Coulomb interactions between electrons.
