2006 escape a/c blower
 

a/c blows thru dash vents then intermitently blows out floor vents. would this be the blower motor resistor or blower control knob on dash? or other? thanx for any info.

If you have EATC,electronic automatic temp control, it could be electronic and/or possibly vacuum related.

thanks Hanky, but i do not have auto climate control, so im hoping it is something easy to figure out and repair.
