I have checked as the truck warms up, one hose first warms up then the other as the water goes through the core. The blend door operates to change from defrost, windshield, to the floor, heater, but with no heat. Is the blend door also the directional door? How to fix and gain access, even if I can get the door (baffle) to open manually to let the air to blow into the heater core, if that is the problem?
