there are two separate actuators for the rear system. one controls temperature and the other controls vents from head to feet. mine problem was the later. that acutuator for esv 2003 is 89018365. it is located just below third seat cup holder passenger side and can be replaced simply by removing cup holder. triangular shaped part with wire harness.
