A couple of suggestions....

heater control cables, a couple run across the heater/ventilation box and
are "held" in place with adhesive tape - maybe one or two have come adrift
and the housings are rattling against the vent system?

The plastic vent hoses leading to the defogger outlets? Th outlets
themselves?

The ashtray?

A bit of schmumpf ?
