keep in mind the heater lines are an extension (so to speak) of your coolant system that runs through your radiator.
The fluid flows through the radiator and then through a heater core, which also looks like an itty bitty radiator. So
even if the heater is off, you will still get a little heat out of it. The best way to fix this issue is to have a shut off
valve on the heater hose that feeds the heater core. My old chevy van had one and I just turned the valve off during
the summer months. The valve looked just like a faucet valve you'd see on your outside water spigot, others look like
a lever that was on if inline with the hose and off if at a ninety degree angle to the hose. It was a great system though,
however it did have its inconvenience when I needed the heat and had to go pop the hood to open the valve.
