What is this white plastic rod?

I removed the dash on my 1999 T&C to re-solder the circuit board and this rod fell out. I can't see where it fits back in. Can someone help?

Here's a wag. A standoff that pushes into the circuit board or surrounding case to keep it from touching something close by?

Well, I'm through scratching my head and hunting for a hole to poke it in. Maybe a previous owner's kid stuck it in the AC vent.
