Focus MK3 2012 Blower issue

[Antdawe]

Hi everyone. 
 

I have a 2012 Focus Titanium. 
 

The blowers sound as if they are at full speed however when switching to windscreen setting very little air is actually coming out. Works ok on front facing vents but not brilliant. 
 

where would suggest starting to check to diagnose the reason?

 

thanks

That's what happens with mines the only option is windscreen only, fans only, windscreen and feet, fans and feet and feet only.

Thanks for that. 
 

my issue was the fan speed was set to full but very little air was coming out. 
 

finally found the cause and it was the pollen filter blocked solid.
