[QUOTE="Vman, post: 442172, member: 22091"] Get the engine up to operating temp and carefully feel the two hoses going to and from the heater core. Hot coolant goes into the core in one hose, and comes out the other. Both should be about the same temp. If not, you may have a heater core blocked up and need a flush or to replace it. If that's not it, there are two other things that can cause it. Either your selector knob inside the cabin, or the blend door actuator. There are videos out there that cover all of this if you search on them. [/QUOTE]
