Which part is broken with my A/C? - GMC Envoy Denali 2005

Asked by Guru9JGGSC May 21, 2023 at 05:10 PM about the 2005 GMC Envoy 4 Dr Denali 4WD SUV

Question type: Maintenance & Repair

I have an Envoy 2005, 5.3L -  My climate control system is blowing air
through the defrost vents & floor, but won't transition to the standard cabin
vents. I get heat but no cool air / a/c. I can turn the air flow up/down, but
can't get the flow through the standard vents. Any idea what part in the
system is the cause? Any help would be appreciated! Thoughts?
Thanks in advance!

Blend door actuators, may need to be reset or replaced. Typically this will happen when the battery is disconnected with the air still in the on position.
