I replaced the two "quick release" heater core connectors front and rear that were leaking coolant 3 days ago. No more leaks. For the first time this year I tried the rear heat this morning. Nothing, just blows cool air. I'm hoping its just an air bubble rather than the controller. Is there a way to verify coolant flow to the rear? Both hoses from the engine to the connectors, and the two thin metal return lines are hot to touch after driving.
