Heating and air system won’t turn off and temperature control doesn’t work

Hello, sounds like a climate control system issue. Check for blown fuses. Also, is this vehicle possibly still underneath the 3 year / 36,000 mile factory warranty? If so, see your local Nissan dealership! Beyond this, do you have any aftermarket components installed? Your concern sounds more like outside influence (something added on causing conflict) than a defect. www.repairpal.com/repair-shops
