Radio and Temperature Lights Dimmed

I have a 2003 Honda Accord EX. One night the panel lights for the radio and temperature controls just went out. I checked the dimmer by the odometer- the two were unrelated. I found that I could barely, barely see the digital numbers in the daytime, so I know the thing didn’t blow out. What’s wrong? Oh yeah, the vents above the panel stop blowing air when I turn the heat on. Ugh.
