Electrical/sensor problems? Dome light, clock, open-door light....

[porkchop]

Hi, new here...

The clock on my Aveo constantly comes on for a few minutes then goes off for another few minutes. The dome light also no longer works, I've changed the bulb a few times, still does not work. Also, the HUD light that tells you that you have a door open is constantly on... even though all the doors are closed.

The alarm a while ago also used to go off on it's own constantly and eventually it has just stopped working. The car no longer whistles when I lock it. I think there are a few minor things but it seems either those problems went away or I've forgotten about them because they've become so minor.

I'm wondering if anybody has some ideas where I should check to see why I'm having these problems and if they're linked? Fuse? Sensor problem?
