Heater stopped blowing

What is your question?

Started acting up in summer, one day it's fine, next day, blows very low, now heater does not blow at all. I can feel the cool/ heat, just not blowing air

What makes this problem better or worse?

When I turn ac/ heat on

How long has your 2008 Kia Spectra had this problem?

Noticed it acting up a couple months ago
