Help needed with fuse for ventilated seats

[gmatx]

2021 GMC Sierra 2500HD AT4

My ventilated seats stopped working a while ago. The manual shows a fuse in the left side instrument panel fuse block, Fuse F6, for "Heated and ventilated seats left/right". That 15A fuse appears fine.  The manual also shows a fuse in the right side instrument panel fuse block, Fuse F20, for "Ventilated seats".  I am missing that F20 fuse. I don't know if it's always been missing, or if I accidentally removed it when I was hard wiring my dash cam last year.  Can someone please tell me if I'm supposed to have the F20 fuse on the right side, and if so what amperage it's supposed to be?  Thank you.

I was able to figure this out. I was missing a 15 amp fuse on the right side fuse box, in spot F20. Once I put one in my ventilated seats started working again.  Yay!
