my saturn relay does not blow air from the roof vents just the floor. on 2005 Saturn Relay

it blows cold just won't switch to the roof vents

Asked by for the 2005 Saturn Relay
Check the owners manual some do heat from the roof and A/C from the floor , that simple.
You might have to remove the plastic panels from the left rear inside of the van to see if the actuator motor is switching the vent door.
