When it rains? Sounds like a bad heater core.

SOURCE: 2003 Lincoln Navigator door sensor problems

One of your courtesy light switch's is defective, it can be in any of the five doors (rear hatch has 2), Ford can determine which one (courtesy light switch) is at fault by using a NGS (New Gen Star Tester) to monitor the switches through the Generic Electronic Module of your truck, these switches are attached to the door latch assembly and are time consuming to replace, so the Ford tester is the cheapest option.

A safety feature on your car is that it will not shift out of "park" if you are not applying the brakes . Make sure your doing that while trying to shift out of park .

I have a 2003 Nav with the exact same problem. I've found it diminishes when taken out of overdrive. Also it's intermittent but more towards bucking. Sorry to post this under solutions.

03 Navigator. Right front strut falls over night. Have replaced the bag, seals and solenoid. What else can it be?


It could be the airline from the pump to the bag Solenoid. The bag Solenoid is shaped like an injector. There is also a Vent Solenoid (shaped like a cube) which is away from the bag. Use soapy water to detect leaks.

Would be interested in what you found and I hope my solution helps you.

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.

I am getting no rear heat what could be the problem?


The actuator needs to be replaced that is behind the rear panel on the passenger side. NAPA has this part for around $50. To get this panel off and make the access easy, take out middle right seat and rear right seat. Once you get all of this out of your way, you will see two actuators, one for vent (roof or feet) and one for heat & cold. Took about 3 hours from start to finish and this included a trip to NAPA.

Coolant vapors coming through vents


Sounds to me like a leaking heater core, probably just started. Quite an extensive operation to replace. If you happen to be in a cold climate, the windows will undoubtedly fog up. Hope this helps
