2008 Expedition Heat Inconsistencies
People Smarter Than Me:
My heat comes and goes. Hot in back consistently.
Comes up to set temp when I put car in neutral and keep at 3000 rpm. I did
this to see if I had heater core issue.
Checked all the obvious things first. Coolant levels, t-stat. Blend doors for
front floor have always been an issue but heat at windshield and dash
previously fine.
Water pump issue?
