Crazy Blinking behavior

New to the Maxima family and just bought a 2002 Maxima SLE. Love it and just turned 30k miles. Just last night I started getting some kind of indicator. I know it's trying to tell me something but I don't know what. When I turn the ignition on the blinker sounds and turn signals and clock flash for 30 seconds, then pauses another 30 seconds, pause and then about another 15 seconds and then goes away. No dash panel indicators on... Not the typical rapid blinker sound that I have heard in other vehicles when your blinker bulbs are burned out...

I am sure this is the place to get to the bottom of this. So thanks in advance for any insights...

Spud..
