I pull a snowmobile trailer with two side marker lights and three driving lights, and the lights have gone out. Brake lights and turn signals still work, so I'm thinking it's a fuse. I can't find the fuse that would control this, any ideas?

 

I'm not really familiar with MDX but did you check the passenger door? Some Acuras have a 2nd fuse box.

 

Took it to the dealer and mechanic showed me another fuse box behind third row seat. You have to fold left back seat partially down to see it.

 

Thank you for the trailer light info! I could find nothing in the owners manual on this. Since all my lights were gone on the trailer light harness, I figured it was a fuse somewhere hidden.

Mine was behind the 3rd row seat diver's side. Like mentioned above, you have to fold left back seat partially to get access. There's a small opening with a wire harness that has 2 small 7.5 fuses. Both of them were blown (tried to connect to a different trailer that must have had shorts in the wiring).

Anyway, replaced and all is right with the world again.

Thanks again!
