Since it's been raining here in California I have been having trying to use the defogger (for the front windshield) and I notice that it was not clearing my windshield as fogs increase as I turn on the heater in the inside. First thing that came to mind is it might be a climate control. But yesterday I did that and guess what it wasn't it. So I am here out of idea on what to do for my issue. Any help will be nice. Thanks.
