Having problems with your 2003 Lincoln Navigator ?
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.
