Dashboard clock doesn't work and odometer resets to 0 each time I turn the car on
 

Does anyone have any idea what happened or how to fix it?

Also, I installed a new dome light I got from eBay - maybe that could be the problem

Thanks

That would be a good place to start, reinstall the original dome light and recheck all fuses are working to see if things return to normal. Possible that the new dome light is drawing more current than the original OEM one, however I am stumped as to what relationship the dome light would have with the clock and your odometer resetting to 0.

Im going to go take the light out right now, will report back soon

Bump.. Removed the lights and all the fuses are good.. any other ideas?

I actually had this problem recently. My problem was the battery connection on the positive terminal. It didn't drain the battery or anything, but it did reset my trip back to zero and mess up the time on my clock. You might want to check that.

I checked that.. its all good.. any other ideas?

The clock and the odometer have a battery backup circuit that saves the settings. The fuse for it is #12 value of 10 Amps. Although if this fuse is blown a few other thing like your clock security indicator lamp, NATS and what Nissan calls the board computer would also not function properly. It looks like it would also effect the memory of the Heating and AC setting and your phone power jack as well. Also you auto seat positioner memory if you have that feature it would not work.

I have same problem on 2000 maxima. Clock, security don't work. Odometer rests every time start car. Electronic parts fuse blows every time I replace it

You have to figure out what is blowing the fuse. Easiest thing to start with is to unplug the clock and see if the fuse still blows.
