I have a 2007 honda crv. None of the interior lights work. I checked the fuse under the hood and it was ok. I then replaced it anyway with the spare. It still didn't work. I checked the map light bulbs and they appear to be ok. I even replaced one with a new bulb and it still didn't work. Any ideas would be appreciated.

 

There's another fuse under dash, I think it's #13 small interior lights. Or #22 7.5a. Under the hood. Aside from that you'd hafta pull the light down and check for power at the plug behind the light. If nothing there, follow wires to the next connection and check there.

 

Hi the attached document details the parameters required for the interior lights to work and the wiring diagram – Page 2 shows the wiring diagram.
The workshop manual also relates to using the Honda diagnostic tool, so it might be worth a visit to your local dealer.
