Chrysler Sebring Convertible 2004 Dash lights flicker and go out when headlights or just the amber lights are turned on Any one know why?

The rheostat in the light stalk is dirty and getting a bad connection causing the dash lights to flicker dim to bright and so on. Try turning the reading and dash lights on and off several times moving the rotary switch from all the way off to all the way on abd back several times. This sometimes will clear the problem for a period. If not, the light stalk will require replacement.
