PONTIAC MONTANA HEATER PROBLEM

2006 Pontiac Montana

Thank you for your time and answers. I've been tryin' to fix my wife's heater. But to no prevail, my last resouce is to disconnect heater core and flush it. Blows good air, changed cabin filters, thermostat, the door works good, core gets hot to touch.

Check to see if power is going to actuators on heater box itself. Onedirects temp the other direction. Pic enclosed.
