2012 silverado 2500 crazyness

[2012 2500 dmax]

Hopefully someone here can help out cause i'm ready to surrender.

2012 2500 hd with power memory and adjustable pedals driver seat.

Driver seat adjustment controls won't work unless i unplug the motor for the pedals adjustment.

With the plug unplugged from the adjustable pedals motor all the seat adjustment controls work fine as well as the memory.

At the motor for the adjustable pedals i have verified the 5v ref as well as the position sensor output, both are fine.

Tried a new seat control module, does the same thing,   

 

Hopefully i didn't post this in the wrong section, sorry if i did and please move as necessary.

 

Thanks.
