I’m now in my fifth winter with the Land Rover. And every winter I spend some time bitching and whining about the little truck’s heater. Less since the F-150 joined the fleet because it has a great heater and has become my winter vehicle of choice on really cold days. Yesterday I noticed two white-ish tabs on either side of the Rover’s heating unit near the floorboard.

When I gave it a tug a small door opened on the side of the heater. A vent. Aimed at the driver’s feet. Another one of the passenger side. Fuck. Me. Warm air (not hot, mind you) came flowing out. Since I never have a passenger, I’ll leave that one closed so all of the toasty air comes my way.

My understanding of how the heater works is water gets warmed by the engine after it’s been running for a bit. And that water (somehow) heats the air that gets blown into the passenger compartment. To make this happen there’s a small brass valve that must be opened in the winter and closed in the summer.
