03 Navigator Ultimate door ajar message running board won't retract

[mthiese]

I just bought a 2003 Navi Ultimate. The running boards were sqeaking when they retracted and extended. I put some wd40 on the moving joints thinking that would solve the problem. It didn't. Now I'm getting a door ajar message and the running board on the driver side won't retract when the door shuts. It retracts when the car starts moving but then extends again when I come to a stop. It's annoying. It's probably a sensor, but I don't know. Any insight would be appreciated.

RETRACTABLE RUNNING BOARD DEPLOYMENT CONCERNS
Publication Date: September 9, 2004
LINCOLN:
2003-2004 Navigator

ISSUE:

Some 2003-2004 Lincoln Navigator retractable running boards may exhibit false reversal, partial deployment or retraction and/or jerky/noisy operation. This may be due to mechanical binding or damage to running board deployment mechanisms.
ACTION:

Verify there are no hidden debris in the running board tracks that may cause the condition. Clean the running board tracks with a high pressure washer if available and test the system again. If the condition is not corrected follow normal Workshop Manual diagnostics. If the condition continues refer to the Service Procedure for component testing and replacement.

DO you have a warranty??

That will get the message to go away, but the other half is what Fordace posted.

Good luck.
