My '06 Commander seems to be having some electrical problems. The rear assist lights come on, the auto high beam/low beam changes on the computer, the air bag light comes on & chimes. If the A/C is on, it goes from face to feet & back up. I've had it in & the dealer changed the ignition switch. This didn't fix it. I've searched the service bulletins but don't see anything specific to that problem. Any thoughts?
