Interior lights work if I manually push buttons but don't work when any door is open.

Do you have the switch on the dome light set to turn on with the doors open?

What trim Civic? (DX, EX, LX, etc.) Dome lights are separate from the front map lights so it's possible they burned out.

It is LX

You should have one dome light in the center of the ceiling. That is the only light that comes on when the doors are opened (granted the switch on the light is properly set). If the switch is set correctly and the bulb doesn't come on then it has likely burned out. The plastic cover is easy enough to pop off and check.

You are probably right. I was thinking on my other Civic that the front lights also came on. Will check. That's be great if that's all it is! Thanks!
