My husband installed the update last Friday on our '23 Yukon AT4, and Sunday when we drove, the A/C on the drivers side wasnt working, only blew hot air, passenger side worked. Have not driven the car until today and now both sides of A/C do not work. Call into GMC service to bring it in to get fixed. Anyone else have issues with A/C after installing update?
Did update and now A/C doesnt work, only emits hot air
