No heat

Well, grampus, (as one to another) since nobody gave you any help yet...your best bet would be to get a Haynes or Chilton manual for your vehicle and check out the procedure for replacing a heater core. It can get pretty involved, and time consuming. Hopefully there is an access door for easy removal of the core. But on some, you have to first remove the heater case to get at the core-very tedious job. The actual procedure for your car will be necessary.
Good luck, Alphonso. And merry Christmas.

2000 lincoln navigator when i turn on my heat i smell antifreeze from the vent and moisture on windshield

you have a heater core leak. If you start seeing coolant on the passenger side floor, that is another dead giveaway. This is not any easy replacement, you will have to remove the entire dashboard. Heater cores are pretty cheap though, the last one i bought was for a dodge, it was $35.00. I hope this helps.
