Diagnosing/fixing seat that won't go forward Denali

[Bucky1]

2011 passenger seat won't go forward. It seems to be all the way back. Move switch to the rear and it clicks. Move switch forward and no noise or anything. Where do you start with these? Anything that it usually is?
The seat will move in all other directions.

I have read on here that the wiring harness can get pinched, you have to pull the cover off the back of the seat to access the harness, others have replaced the switch and had success, I personally haven't had any problems with the seats so that's all I can share about it.
