The left (larger) 3rd row seat on my 2015 Suburban LSX no longer collapses when I press the button in the back. The motor grinds, but the seat does not move. I can certainly take it in to get it fixed, but I need the seat down ASAP. Is there a way to lower the seat manually? Even if I need to remove some parts in order to pull some wires to unlatch it.

 

Most seat mechanisms are now driven by a cable that the motor powers. Pulling out the seat is the only way to really see what's going on and to repair it. Doesn't the 3rd row come out completely by unlatching from the floor ? They do on my Tahoe, not sure on a Sub though.
