Is your temperature gauge drop closer to "C" when the vehicle is moving at high speeds?? If so, this may be a stuck open thermostat, or missing thermostat. Replace to prevent this issue. Hopefully this helpd!!

Change the thermostat and see if that heats up the Lincoln.Here's how to do it.After removal,it should be closed,to check it,put in pot of water and heat to 183 degrees and it should open and close after you take out of water.
This sounds like you have a pcv hose that has become an open vacuum leak. It is located under the upper intake, or given the year your air filter box may not be correctly sealed and possibly have a mass air flow sensor concern. Any Check engine light or codes to work with ? I f you have further questions just leave a comment on my page,
mine was the same. I took it out on the hiway and ran it at 5 grand for about ten minutes and it seemed to flush out the heater core and now it works fine.
- If temp guage reads normal, the lack of heat may be due to the Heater Control Valve. Located in front of the radiator. Lower passenger side. A real bugger to replace.
- The plastic cap just over the thermostat is key in re-filling the anti freeze and bleeding air.
