defrost

hey guys my heater ,a/c control went up the other day so i decided to bypass the fan to a switch, i can get everything else to work floor vents ext. but no matter where i turn the lever behind the glove box i cant seem to get any air out of the defrost vents. i see there are alot of vacuum lines under there is there any way i can rig it to come out the defrost for the time being?
