I just had a similar problem with my 2001 T&C (although I did not
check the codes).  Engaging the turn signals or hazard lights
would intermittently cause a power failure to the instrument
cluster.  I swapped related fuses, relays, light bulbs, etc.,
cleaned all contacts, took apart the multi-function switch
and cleaned it, removed the instrument cluster and cleaned its
contacts, etc.  The problem went away for a day, and then
the instrument cluster went out altogether.  I took it to a
dealership.  They replaced the instrument cluster, after
which there was power to the cluster but still flickered.
They replaced the multi-function switch and BCM, only to find
that the instrument cluster still flickered.  Eventually they
found a ground contact in the engine compartment that apparently
was corroded.  They cleaned it, and now the whole system functions
as it should.  (Still not convinced I needed the switch and
BCM...  They charged for those parts, but not labor for
installing them.)

Good luck.  Frustrating problem.
