You could also install a valve in the supply side heater hose located in the engine compartment if there is room. When closed this will prevent hot coolant from reaching your heater core thereby preventing heat transfer. You can easily open it up to drive in the spring/fall as required. The PO of 18309 installed one in the downstream return hose, replacing the stock vaccum valve. This works great for me. I am also in Mpls and have driven into Nov as long as there is no snow/salt etc. Just another option.  Best of luck
