Sorry about the late responce. Here you go... The 1st pic is the heater box assy. The 2nd is the defronts/floor vacume pod i am pointing to. Check this for vacume.if none then check to see if there is vacume going through the fire wll from the motor. If you do have vacume here the door is jammed(pic 3 ) . or the vacume pod itself is bad.
