You have a problem with your blend door actuator. Every year, twice a year, my husband manually moves the blend door actuator and puts a tie wrap on it so it will stay in either the heat or cool position. You can reach this through the glovebox, which you will need to remove. I had this fixed at the dealer once long, long ago - very expensive because the plastic piece that needs replacing means they must remove the seats and the whole dash area including the steering wheel to properly replace what is broken. If you want to see how that is done go here: Much easier going through the glovebox.

No, But it isn't a wise decision. What if you get it back together and the other side blows a week from now.

Will new thermastat restore heat to my 1998 lincoln markviii lsc collectors edition?

If the engine seems to be running well, the problem is not likely with the thermostat, but with the blend door in the heater control box. These have a tendency to get stuck over time. To see if the have the potential for heat, warm the engine up to normal temperature. Then under the hood, find the heater hoses. They are smaller diameter hoses (about one inch in diameter). There are two of them one runs to the heater core, the other is the return line fell both hoses. If they are warm to the touch (almost hot), then you have coolant thru the core. If only one side is hot, then you may have a clogged heater core. If there is heat on both, the problem is in either the dash controls for the heat, of the blend box under the dash.

I hav a 1998 Lincoln Mark 8, my AC works, but no heat. What is the problem?

Completely separated systems: the cool comes from an evaporator powered by the compressor, the heat from a radiator from the cooling fluid heated by the engine. If you don't have heat then either the radiator / heater or the controlling valve are clogged or respectively blocked shut. Try to clean them by running a radiator cleaning solution. If that fails the dash will have to be removed to access the heater to remove it and valve for a thorough cleaning and/or replacement.
