I'm freezing my butt off in my 1983 Mark VI because I'm getting
very little heat. I've replaced the ambient air sensor in the dash
and checked for restrictions in the heater core. Also have replaced
the coolant sensor on the heater core hose and bled the system for
air. Additionally, the door on the passanger side campartment
functions properly and all the vent controls seem to operate fine.
I'm guessing internally the blend door is not working right. The AC
system is fine and works very well. So why don't I have any heat??
One other thing, the blower motor works at all the settings, yet on
high it does not blow nearly as much air as it should, like other
lincolns or any car for the matter. Thanks
