New Jersey 1998 Chevy Mailibu

I need a price on two parts if you have them for my 1998 chevy Malibu base (with rear defrost option and V6 option, automatic trans,) :

1 - AC/Heater control unit - ACDelco 15-72846 (this is a controller with the rear defrost option on it) - actually a button on the controller board inside the plastic housing is bad but there is no part breakdown so I can buy just the button to solder onto the board. Maybe, if you have a damaged unit I just need a button or two off it. The recycle air button does not work.

2 - the cable/assembly for the driver side manual seat back adjustment (tilting seat back and forth) - currently the cable in there only disengages one side and not the other. I think the passenger side might be the same. I do not see how to adjust the cable and its stretched out somehow by the previous owner.

Please let me know, thank you.
