Has anyone taken apart the Air Intake Selector button on your HVAC controls?  Its the one in the middle of the Air Flow Selector (far left knob).  I accidentally opened mine(converting to LEDs) and there are a lot of tiny parts.  It is also spring loaded so it sprung open.  And now I can't figure out how to put it back together.  I have it back together, but it will not click.  The problem I'm having is with a little cooper piece and a small silver staple shaped piece of metal.  Any help or suggestions would be appreciated.
