You need to recalibrate the climate control system.

  • Start the van.
  • Slide the temperature lever all the way to the left (full cold).
  • Turn the Mode Control to 'panel' (the one that sends air to your face only).
  • Turn the 'blower switch' to all the way to full.
  • Now go to the leftmost three buttons. Press and hold the top one (rear wiper on constant) and the bottom one (rear wiper washer fluid) until the lights come on solid then begin to flash, and then you can let go.
  • The AC will now calibrate. You will feel the air blow out of all the different zones at different intervals and see lights come on and go off. Then after a minute or two the top button you pressed will be slowly flashing. This means it has been completed.
  • Press the last flashing button and you are done.

Alternate Method (w/o Scan Tool)
Clear all DTCs.
Place the ignition switch to the OFF position.
Install the HVAC actuator.
Connect all previously disconnected components.
Remove the HVAC/ECAS fuse for a minimum of 10 seconds.
Install the HVAC/ECAS fuse.

Changed battery in my 2004 GMC Envoy and now my a/c only blows from the dash and rear vents. What could be wrong and where is the part located on the vehicle?

There are a couple of possibilities, one is that the HVAC system lost its calibration during the battery change or the actuator that controls the vent door has gone bad.
To recalibrate the HVAC system, set all HVAC controls and switches to OFF or fully CCW positions. Disconnect the battery for about 3 - 4 minutes, then reconnect the battery. Do not touch any of the HVAC controls for a few minutes, then try the controls to see if the air flows correctly.

2 wheel drive or 4 X 4 ? Automatic or manual climate control
Do you know what DTC'S - diagnostic trouble code's are ?
DTC B1375
The ignition 3 voltage circuit is a discrete input to the HVAC control module. The HVAC control modules uses the input to determine that the ignition switch is in the RUN position. When the ignition switch is in the RUN position, ignition voltage is applied to the input.
Rather then guessing as to what the problem , not being able to diagnose properly , your best bet mite be to have a qualified repair shop check it out . Would need to hook up a professional or factory scan tool to check code's ,see if the climate control module will communicate with the tool .
HVAC Control Module
The HVAC control module is a class 2 device that interfaces between the operator and the HVAC system to maintain air temperature and distribution settings. The battery positive voltage circuit provides power that the control module uses for keep alive memory (KAM). If the battery positive voltage circuit loses power, all HVAC DTCs and settings will be erased from KAM. The body control module (BCM), which is the vehicle mode master, provides a device on signal.
