I purchased new heated chrome cap side mirrors for my 2009 suburban LT with turn signal and puddle lamps. They are not power fold. They have a black plug and white plug. I installed mirrors and plugged them into window controller in the spot for black plug and white plug. The mirrors move fine and turn signals work with no problem, they flash when I lock and unlock doors. The problem is the puddle lamps don't come on when I lock and unlock the doors. I brought truck in garage, closed the door to create dark atmosphere, once night lights in interior came on, I shut truck off and lock and unlocked doors since puddle lamps probably come on only at night, but still no illumination from puddle lamps when I locked and unlocked doors. I made sure bulb was in them and good, and also made sure the plug was in tight. My old mirrors were only power and heated with no puddle and no turn signal. They had only 1 plug which was the black plug. Anybody know for sure what I need to do and how to get puddle lamps to come on?????

 

That option may need to be enabled in the BCM, will need to take it to the dealer to program would be my guess...

 

Took to someone today, and they switched out my switches with the switches that have powerfold mirror option and puddle lamps worked well. So thats one option, but guy had those switches sold already. The other option is to see if my switches can be programmed which would be great, if it could be done. Any one know where I can purchase some switches with powerfold option, besides dealer, bc can't find any on ebay at the moment or craigslist.

 

Try your dealer or gmpartsdirect.

 

Yeah they were 98 bucks a pop on there, which was cheapest so far, still looking for a better price, before I pull the trigger and purchase from there.
