I have a 2009 Honda Civic hatchback DX. And when you turn the headlights on all of the gauges quit working. When you turn the turn signals on the hazard lights start flashing. But when you turn off the lights the gauges start working again. Anybody got a clue to what the problem is ?

Sounds like bad Ground(s)?

The Combination Switch may be bad.

I have realized that I typed in the wrong year model of Honda Civic I have a 1999 DX instead. Thanks for the info TxGreaseMonkey. Where is the combination switch located at?

Turning signal, etc. switch. Disconect negative. Battery cable, prior to removing the switch.
