The window lock out/window child lock button is inop on my 2006 LT. It was working OK a little while back and it has suddenly stopped working. Anybody??

Thanks guys..

 

Well its probably the switch itself that has failed. The window switches are in one assembly that isn't really serviceable other than just replacing the complete unit. Good used ones are available on e-bay for about $35 and up, its something you can do yourself.
