I have a 05 chevy malibu classic base model. similar problems. there are 3 settings on the lights. Auto setting allows the odometer to be read and radio back-lights come on. but in parking light setting or lights on setting the odometer dims to almost unreadable and radio lights go out even though you can hear the radio playing music. None of the ac heater lights work and the dash doesn't light up except for the dummie lights. The horn was working, Now the horn has stopped working and the lights on window switch don't light up. I have replaced dimmer switch, turn signal-light switch and dash cluster. I am now told it might be the BCM(body control module)and apparently it needs to get flashed or replaced and reprogrammed at the dealership. Also, when in auto during the day the odometer and radio are illuminated but when it gets dark they go out. No blown fuses now, have jiggled all wires and looked for cuts and shorts in wires.
