That doesn't sound very good. If a bump upset something electrically to cause one thing to go out and something that wasn't working to suddenly work - you definitely have an electrical short somewhere under the dash.
I'd start looking at obvious modications - since you just recently picked up the car - look for wiring that is just hanging or dangling. Possible that someone installed an alarm system and just disconnected the "brain" without rerouting the wires that were tapped. Or there was an audio component (aftermarket headunit, wired navigation, amplifer) that was tapped to the existing wiring.
If nothing seems obvious - check the main fuse block, make sure nothing is obviously suspect there (wires or clips jammed into fuses), remove the gauge cluster itself making sure that power is disconnected first - and see if any wiring behind it was shorted out.
