HI, Just wondering if anyone else is having problems with the heating control in there Toyota 4Runner. I have a 2000Limited 4Runner with 75,000km. The problem is it rarely works when I want to change Modes. Sometimes it does other times I can press the buttons and no way will it change mode!!! The A/C buttons are the same ,if I get it on I can't get it to shut off!!! I took it to the toyota dealer and they want 1385.00 to replace it!!!

warranty?
