A few more details. The interior dash lights, climate control, and stereo lights blink, but not the interior courtesy lights. The rear taillights, license plate light and side marker lights blink along with those on the front except the fog lights. Here'* the wierd part - if I reach in and press the fog light button, all flashing stops and all lights are on. If I turn the fog lights back off, everything starts flashing again. If I turn the headlights on, all flashing stops. If I turn the headlights back off, everything stays off and doesn't do it again until the next morning.
