As the title mentions, I don't have heat in the rear of my 2017 Suburban Premier 5.3L V8 when it's idling. When I'm driving down the road, the heat is HOT, but not if it sits.
I noticed if I Rev the engine to 1000 rpm or so at idle, the heat will work. It seems as if the water pump doesn't cycle the coolant through the rear heater at idle.
Does anyone else have this problem?
