Turn Signal in mirrors

[Kee Fuller]

So, I just installed my newly flashed BCM into my ppt that i got from white audio and media. The turn signals in the mirrors still do not work. Has anybody else had this issue after flashing the BCM?

Not sure if this might help, but my 07 Tahoe originally had the power mirror manual fold mirror's with no turn signal in the glass, and when I installed the OEM turn signal mirrors with power fold, I had to install both driver and passenger side window switches from the other vehicle that I took the mirrors off of in order for the turn signal light to work. I tried just the driver side switch at 1st and only the driver side would fold and light would work, until I went to the passenger side and replaced the window switch from the other truck, everything worked. I never flashed my BCM, I just swapped everything out, hopefully this helps you.

You have zero info on what year truck you have, but I don't think the NNBS PPV is wired for that. Our '10 wasn't anyway.

if it is not wired for it you can just tap into the blinkers at the bcm, but there should be wires for it at the drivers door switch

I wouldnt know where to start honestly

on the drivers door switch there is a mirror wire harness, I think there is 2 harness connectors to the mirrors or there should be, I had a thread on adding the puddle lights to the interior lights so that may point you in the right direction, I had the white connector off and the mirror blinkers were still working so the blinker signal must be on the 2nd mirror harness, I would just start testing the wires on the connector for a signal with the the blinkers or hazard lights going.

I wonder if you swap the door harnesses from a truck that had dl3 mirrors. Would that work
