So I failed the NCT on my airbag light not coming on when the ignition is turned on. I googled a bit and found some folks say it was probably blocked off with tape so I took out the cluster yesterday and cracked it open - no tissue/tape/blocking of any kind. The light doesn't come on and never did, as far as I can remember.

Anybody have some suggested diagnosis steps? I'm just waiting on a cable to fall into my hands
