Having problems with your 2004 GMC Envoy ?
Air flowing thru front vents
\015 My air was flowing through my dashboard before i have an 2004 gmc envoy xuv i had to replace the battery once i replaced the battery n turned my air on it wont blow through my front vents what can i do to make it blow directly like it suppose to\015
When the battery is disconnected and then reconnected, the HVAC goes through a recalibration. Sometimes if all of the HVAC controls are not in their OFF and CCW positions, the recal does not work properly. Try doing the process over again, and make sure that the HVAC controls and switches are in their OFF or full CCW positions. Then disconnect the battery for about 5 -10 minutes, reconnect it and turn the key to the ON position, but do not touch any HVAC controls for about 2 - 3 minutes. This should solve the problem. If not, you have defective door actuator or door gear.
I just changed my battery as well in my 04 Envoy XUV and the air on the passenger side would not blow. The air has since returned after I restarted but the flow on the bottom has been out for some time even before the battery change.
