I have now attached a photo of the panel.
My wife's highlander is a 2002 Limited and the A/C started blowing hot air on the driver side while the left side blows cold air. This started happening just after we pick it up from its regular service and the
dealership says they did not do anything to cause this. Initially was an intermittend problem but now it just blows hot air like the heat is on on the left side. Our highlander has a different panel with only two knobs and it looks different than the one shown in the photos. Any help is greatly appreciated.
By the way, great forum!
