Does anyone know how to replace fog light bulbs?

does the bottom plastic covers have to come off?

 

The plastic sovers don't have to come off. There is one bolt and two tap in screws that you'll need to remove from each side.
The driver side is the hardest because there is no room to maneuver. What you'll have to do is push the black plastic to the inside and finish your work

 

how about replacing the covers? Both of mine are broken from rocks. At my last service the Dealer noted that they should be replaced. They showed an estimate of $650. Can you believe that?

 

shouldn't that be under warrenty replacement?

 

warranty covering rock damage?

 

My dealer would do it for me. Try to talk to the service manager and see what he says.
My dealer is so cool with warranty repairs that last time my friend had a cracked windshield on his MDX from a rock on the highway, he went there and they marked it as defective and replaced it.
