No heat / 2003 Explorer
Have a no heat problem with a friends explorer. All related fuses appear fine, blower is strong, plenty of antifreeze, the thermostat appears to be working fine (engine temp guage normal), and both the inlet and the outlet lines into the firewall get nice and warm.
It almost appears as if the heat/cold fade switch isn't working, but I haven't had a chance to tear that apart yet. Was hoping for some advice. Thanks.
