My controls for the heater and air don't move and the fan only seems to blow low on 1992 Toyota 4Runner

What do I need to do to fix this. I order a new set of cables and buttons to replace the frozen ones. I see that there was a recall on 1992 4-runnner air conditioner expansion valve. Does this mean Toyota will fix it for free?
