2000 Wrangler (TJ). Heater makes heat and the air gets cold but they don't blow?

What is your question?

One day I turned the switch for a different speed for air conditioner to blow, and it was like I had not turned it at all. There were no "clicks" as you went from one speed to another. The knob just turned back and forth as if it wasn't making a connection to make either the heater work or the air. The heater produces heat and the air conditioner makes temp cold, there is just no air flow to get the cold or hot air out. Is this a problem with the switch on the panel, a fuse or is it the blower motor?

What makes this problem better or worse?

Nothing, it just doesn't have air flow

How long has your 2000 Jeep Wrangler had this problem?
