SOURCE: 2003 escalade rear climate control no heat just cold air.
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.

The heater core may be stopped up. Try to back flush it with a water hose.

SOURCE: module location for blower motor on a 1994 Buick
on the paasenger side of the car under the dash. Remove the lower dash panel below the glove box and the module is in the duct for the heat to the far right side of the footwell.
SOURCE: my climate control only blows out cold air but the rear climate control works as it should
Could be the controller or a faulty blend door.
The blend doors direct air thru the heater core and evaporator along with the vents. The controller uses electric motors to change the direction of air flow.
