SOURCE: no air coming out of
i had the same problem on my sub its the blower motor in the defrost i had to take it to a pro
SOURCE: 1999 Chevrolet Suburban ac selector door motor.
it should be under dash next to gas peddle on left end of heater box not that hard 2 screws and a plug. its called heater blend door actuator.
SOURCE: 1999 Suburban, A/C on warm air from front vents, cold air in rear
The car uses the same freon in the front as it does in the rear. If the rear a/c is working, you either have a plugged evaporator in the front unit, or perhaps a bad heater switch. Try switching the heater to hot and see if it blows even warmer air from the front vents. If so, the heater switch is working and then it sounds like a plugged evaporator or maybe a plugged orifice tube. That is a good place to start looking. Hope this helps.

MODE SELECTION IS VACUUM OPERATED. DEFROST AND FLOOR ARE A DEFAULT MODE WHEN SYSTEM FAILS. YOU HAVE A VACUUM LEAK, FAULTY VACUUM SWITCH ON DASH CONTROL UNIT OR A BAD VACUUM MOTOR IN DASH

my issue at the moment is that the linkage (control arms) have come apart. it looks like there's a part missing from between the two control arms. there's a small electric motor with one arm and another arm that controls a flap somewhere that shifts the air flow between floor and up top. both of these control arms have a square hole in the ends and i don't see a way for them to be reconnected. so i'm assuming that there's a part missing.
