If you havent done one, a Lincoln isnt a good one to learn on...but if you do it, just remember, the a/c and heat are disconnected and the entire plenum is removed....this requires some dash removal, support removal, Then once you have done that and get the plenum out, you need to remove the top of the plenum to access the core. If the heat was OK b4 the car was worked on, look for broken or disconnected vacuum lines at the thermal blower lock out, it's spliced into the inlet hose of the heater core, if this isn't working, you wont have good heat!
