Did you ever figure this out? My wife drove mine yesterday and now it won’t recline all of the other functions work.I have a 2008 Suburban and my passenger seat reclined and will not go back up. All the other buttons on the side of the seat work fine. The only button not working is to make the seat come up and recline. I don't know if I just have a switch problem or motor problem. Although I think that if it were a motor problem none of the other switches would work either. Does anyone have any recommendations on where to go from here? Thank you!
