I have a 2006 TSX - the passenger side, overhead center courtesy light was out so I replaced the bulb. However, I can't get the light to stay on. If I push the drivers side light, I hear a click and it stays on. Not so with this side. If I push in the button (white button in picture) I have to hold it in for the light to stay on, but when I release it, light goes off. There is never a "click" on. The same is true if cover is on or off.

 

Replace the unit.
