Added DL3 mirrors, puddle lamps will not work. Help please...
 

I recently took the tow mirrors off of my truck and reinstalled the factory DL3 mirrors. Prior to install, I purchased some donor mirrors from a tahoe with puddle lamps and swapped the necessary parts onto my mirrors. After install, all options work (power adjust, power fold, signal) except for the puddle lamps. Is there something I am missing here?

Truck is 2009 Sierra SLT

Thanks,

Are the bulbs good?

Sig says full LEDs so maybe a LED is bad

Yes, my bad. I have tried leds and a set of brand new incandescents just for safe measure. I know that they should come on with the dome, but I also changed my approach and exit lighting functions just for peace of mind.
