I got the front heat working good, now to tackle the rear.

I replaced the rear blend door actuator which is now working properly. The coolant lines to the rear core are not getting hot. I thought one of the lines was slightly warm. Is there a separate heater control valve for the rear? Maybe the core is clogged?

I think there is a heater valve located between the passenger side exhaust manifold and the upper control arm.
