Hi I took positive cable off my 2008 GMC Envoy and now my not my vents don’t work it only throws on the top and the floor is there a way I can reset it

ID Status Date Year Make Model Transmission Type A/C Controls Public/Private
#14710 In Progress 08 GMC Envoy public

My windows were working before I took out the battery terminal

Sparky

I would start with trying a recalibration of the actuators. I have included a couple of links to help. To start the recalibration of your vehicle the fuse you will need to work with is the HVAC B fuse in the rear fuse box.
