My windshield keeps fogging up while driving. It's almost like the re-circulating switch is not working to allow fresh air in. It has never happened before. I've turned the re-circulating switch off and on and it seems to be working by the indicating light and the noise from the blower. Does anyone have this experience and the fix? This is the first rain after a long hot spell and I have been using the air-con quite a bit. Any advise will be greatly appreciated.
