The heater didn't work in the car. The A/C suction hose (and the upper radiator hose and the heater outlet hose) had been chewed by rodents. I now have to spray rodent-repellant under the hood of the car every two weeks, have bags of rodent-repellant under the hood, and place traps around the car and the house. Ugh! I am now extremely anxious about the condition of the cooling system of the car and worry that the replacement hoses will also attract rodents.
