One evening, I pushed the button to one of my map lights… a little harder than usual.  It turned on, but the button no longer worked.  I had pushed it up too hard, and something had come loose.  Turned out to be an easy fix…

WARNING: as you remove the dome light assembly, watch for very small loose parts.


  • Electrical tape (Optional)


Step 5

Collect your parts. You need to have everything below (1st picture), plus the black switch base which is still connected to the map light frame (2nd picture).  The white piece is still likely also still on the map light frame, but it can be easily unclipped (2nd picture).

Step 6

Reassemble the parts. Leave the button cover out for now.  The small white part has grooves that line up with grooves in the metal part.  The order & direction of the parts is shown below.  With the parts in the right direction, assemble with the black piece.

Step 7 (Optional)

Wrap the 2 base pieces with electrical tape. I found that once my switch had come apart once, it wanted to come apart more easily a second time.  To prevent this, I wrapped the white & black pieces a few times with electrical tape, in a diagonal direction.  I didn’t get a picture of this, sorry.

Step 8

Snap the switch back into place, plug the wiring harness back in, and test.

Step 9

Put your car back together.
