  We compute the monodromy of the mirabolic Harish-Chandra D-module for all
values of the parameters (theta,c) in rank 1, and outside an explicit
codimension 2 set of values in ranks 2 and higher. This shows in particular
that the Finkelberg-Ginzburg conjecture, which is known to hold for generic
values of (theta,c), fails at special values even in rank 1. Our main tools are
Opdam's shift operators and intertwiners for the extended affine Weyl group,
which allow for the resolution of resonances outside the codimension two set.
