heater blower motor question

yes only one blower motor, but i believe that is normal for an a/c and heater box.

one other note.....when i push the a/c or max a/c button the blower motor blows harder. when i push heat or defrost it slow a bit. when i push off...it stops.

with the fan switch in the off position.....and any of the max a/c....a/c....heat....def...buttons pushed it still turns the fan very slow.

this really isn't a big deal...i'll just leave the push button in the off position when air blowing is not needed. i just wondered if it was normal to have blower motor moving when the fan switch is off and one of the buttons was selected.

forgot to add...the control cut out for the dash bezel....it was originally only heater controls...but some point in its life someone hacked it up to fit the a/c controls. its very nice let me tell you.
