HVAC problems , blower?

I've had an issue with the amount of air coming out of my vents ... when driving with it on high it will get down to blowing almost nothing. When I move the position switch it will switch thru perfectly fine .. I've replaced the blower fan , resistor, replaced the climate control face plate and all the switches behind

Any ideas?

Maybe the vacuum pump ? Or the check valve?
