Rear Window Replacement Question

[AE1M]

2016 Silverado HC with sliding center panel on the back window.  Having this replaced by Safelite, recommended by my local Chevy dealer who doesnt do glass work,  Highly recommended from their past experience.  Defroster failed and dealer says unit must be replaced.

 

Questions is where is the connector for the sliding panel and defroster?  I cannot seem to find how to fold down rear seat backs if it’s hidden there.

 

Any info on how/where the electrical connectors might be?

You will need to remove the back seats to get to the drive & electrical connector. Search it on YouTube. Also, there's a hack you can do by cutting off about an inch on the seat back retainer so that the search seat will fold down.
