Whenever my A/C is turned on, patches of fog or mist appears on the same spot of my windshield - middle bottom area. Lumalaki ng lumalaki hanggang mahirap na visibility. Sa labas yung fog. I use my wiper to clear it off pero bumabalik. It's not even very cold inside the car. Tama lang. The only way to quickly get rid of it is to turn off the A/C and roll down the windows. This can happen no matter what the temp is outside. May nakaexperience na ba ng ganito? How do you fix this?
