2012 LS3 no heat driver's side only

My 2012 1SS LS3 has a weird (to me) heater problem- air is hot on both passenger side vents, barely above ambient temp on driver's side.


Naturally I have not been using the heat. Until today in the rain. Windshield de-fog is a joke.


I do get a slight whiff of coolant under the hood. I see nothing but dry engine and hoses etc however. Under side of hood dry. Couldn't get under it- it's raining and I am still recovering from stroke. Coolant temp never went over 205, and that was in a 300 yard line of stopped traffic.
