Hey guys, any ideas what's going on with my wife's Taurus? Her heater isn't working.. here's what I've troubleshooted thus far.
I can hear the blend door actuator (I think that's the name) motor moving when I turn the knob from hot to cold, and back. However, when I turn it from hot to cold, when I kinda hear a noise as if it's sealing, or something. I don't hear that when I turn from cold to hot.
I used my temperature gun on the hoses that go into the heater core, with the heater off, one was around 180, the other 170, with the heater running, one was 150, the other 160.
I replaced the thermostat approximately a year ago, coolant level seems fine. One thing I notice is if I leave the fan off for a while, but keep the temperature turned to hot, if I turn the fan on, it initially blows a bit warm, then goes back to outside temperature.
I was initially thinking it was the heater core, but the temp gun reading is making me think otherwise now.
