A few months ago, me and my wife bought a new 2007 Lincoln Navigator L for $63k. Nice SUV. But, l noticed this morning the power running boards would not go down. It must be the motor. Help Please!

contact the dealership you bought it from

shoul be under warrantary take it back

It is probably NOT the motor. More than likely u accidentally disabled the feature.
Your owners manual tells u how to re-enable the power deploying running boards .
l will paste a copy of the directions for u :

l THINK i'm right on this ( l hope u will let me know!) but if l am not, ur vehicle is covered by a bumper to bumper warranty & it will be no problem to repair !
l hope this helps.

trust me, ethol is always right. it would be kind of strange for the running boards to stop working when they are a pretty simple piece of machinery. my dad is 03 navigator is running boards never stopped working.

take the damn thing back to the dealer its under warranty why ask such a question here you do not have to fix it.

If resetting the feature does not work it is a blown fuse. Warranty work, take 'er in. Good luck.
