Camry interior overhead map light does not work. In order to turn it on, tried to press it. But did not pop up, neither turn on light.

There are two interior dome map lights on roof of front seats, they attached together. One is on driver side, which has problem. Another light is fine, on passenger's side.

I guess some spring switch is broken. Any idea how to open the light and fix it?

Thanks in advance.

 

Open the plastic cover, both the press button and light is OK. Put plastic cover back to original position, it seems it not easy to turn on by press.
