The common cause of this is a failed air temperature control. blend door and or the electric actuator that moves it. The dealer can do a test scan to confirm this, the repair is very expensive if the blend door is the cause and it has burnt out the actuator motor because the door is warped and jammed, which is the most common cause.

To check the rear expansion valve, see if the a/c lines are different temperatures. One line to the rear evaporator should be hot and the other cold if it is working.
Try to recailbrate the blend door actuator. Remove the HVAC module fuse. Wait at least 15 seconds. Replace it, turn the key on and wait 40 seconds

Could be the HVAC control processor is malfunctioning.Wtihout testing that would just be a guess .

It's possible the HVAC needs to recalibrate itself, try the following;
With key on, set all HVAC controls and switches to their OFF or CCW positions. Turn key off, disconnect battery for a few minutes, then reconnect battery. Turn key on, but do not touch any HVAC controls for about 2 - 3 minutes. After that, see if the vents and all other functions work. If this does not solve the problem, either the mode control actuator(s) or mode door(s) are stuck or defective.

remove the HVAC fuse from the underhood fuse block. Wait 60 seconds. Reinstall the fuse. Turn the key to the run position, do not start. You should here the actuators running through there self test. After about a minute or two it should be all done.

Sounds like a bad blend door actuator. That's the motor that diverts air between the heater core and AC

That's default mode when a problem exists. By which mode does door function, cable, vacuum or electrical. Start there

the most common problem here is a defective air temperature control blend door actuator, this is what moves the door that controls air flow across the heater core or the ac evaporator core, to replace this requires u remove the dash assembly.
