Do they still think your AC is broken or is it that it can't handle the heat and humidity where you live? I do notice that my climate control swings pretty high and low. I've had better "auto" climate control in other vehicles than I have in this LR4.
Just continues to stop working. It really seems like it has a mind of its own. Everyone is pretty stumped. I'll send you an update soon on PM as to what's going on.
