Hello all. Haven't been here in a while. 2004 Lincoln Town Car, 4.6L. I have a problem with my heater. The heat doesn't (always) get hot even after the temp indicator is in the fully warmed up indication (middle of the gage or a little bit higher). Most time's, after driving a while it'll eventually turn on and get hot. The fan comes on after the temp comes up, so I believe the temp control is working, but it blows cold air...until it decides to blow hot air. I think there is a Heater Control Valve controlling coolant flow into the heater core, but I can't locate it. Can you guys point me in the right direction? Where is this valve, and how difficult it is to replace? If I'm on the wrong track, I'm all ears!
