Dash and radio lights don't work at night. They are on during the day. 2003 Chev Impala. Have checked all the fuses.

The same thing happens on my 2003 Impala. I found that my dimmer switch has an intermittent failure where sometimes the dash lights go out even with the headlights on.
If I wiggle the dimmer just right, the dash, radio, steering wheel, door locks, and every other light comes on (when the headlights are on). My fix was to mount my Garmin on the steering column in front of the speedometer so when the lights go out I know how fast I'm going. A replacement dimmer (or bypassing the current one and adding a resistor) should take care of it.

The auto door lock feature dose not work.

There is 3 relays in one of the fuse panels that are labeled doorlocks one of them is probably bad. Push the door lock button and find the one that is clicking this is the one that is back. This should fix your problem
