Same problem here...
I've got the automatic AC/Heat on my 2002 limited. Some of the buttons (AC, Auto, Defrost) only work some of the time. It's not a matter of how hard you push them, because when they are working you only have to touch them lightly. Also, when one doesn't work, the others...
I'm impressed....
I just changed my oil filter for the first time on my 2002 4runner. I kept the skid plate in place (maybe that was a bad idea???) and oil apparently spilled on top of the skid plate is slowly dripping near the rear of the plate. It's not something I can even clean up...
