This weekend I had the battery disconnected for a time and now when i select feet it blows out of the defrost, when I select defrost it comes out of the feet, and i cannot get it to come out of the middle at all.
Called a couple dealerships and they cant get me in for a while & state that they would need to reprogram the system.
Thought id come here to see if anyone knows of a homing or reset procedure that i can do myself to save $140+ just to have them pull it in the shop.
This is a 2019 Silverado High Country.
