Not sure what you mean. There is a dial for temp and one to select where the air blows out Dash floor defrost etc an A/C button & recirc.
Chevy Mechanic: Dan, Technician replied 2 years ago
It sounds like you probably have auto control and the most common problem is the blower motor control module. Here are testing/replacement instructions. Let me know how it goes or if you have more questions, thanks.
