Sounds like a grounding issue. Is the whine there even if the vehicle is off ?

Some vehicles have a power supply for the dash lights.  The dimming of the lights changes the duty cycle of the power supply.

What year Sebrings are we talking about here ? If they are newer ones, just bring them back for warranty.
