I have also unplugged a heater core by hooking a hose and put the outlet hose in a bucket. Lotsa crap came out and then there was flow! I'd trry flushing in both directions.

 

Hey All,

After just cleaning out my rear heater and re-routing new hoses as the original small-diameter metal ones were COMPLETELY clogged, I'd do a flush first and then see...maybe check the valve to see if it really is opening (and allowing water to flow!) when you shove that lever to RED...

Just fixed my 91 4Runner. It was one of the connections under the glove box. It was just disconnected.
