Hi!! I just purchased a 2012 ram longhorn laramie 4X4 truck about 2 months ago. It has a 6.7 Cummins. I have noticed that it has the turn signal on the tow mirrors. They are not working. I put a test light on them and I am not getting any juice to it. Of course there is no owners manual with the truck. Any suggestions?

 

If they were added to the truck after purchase previous owner may not have taken to dealership for programming. My 09 had tow mirrors i added, never did have the signals or puddle lights activated.

 

I believe they are factory. The puddle lights work.
