Foggy windshields for car are a real safety problem. Foggy window makes it difficult to determine out and for that reason dangerous they are driving. Especially when it’s raining and the automobile windows need to be rolled away this can be a huge difficulty.

The problem might be a whole lot worse if the haze about the windows has a filmy uniformity preventing the view in reality even after wiping the windows off. If there's a filmy scum it could be an indication the radiator core is leaking.

When heater cores leak - it smells! It starts out to become a sweet smell but as the coolant soaks into the carpet it begins to sour producing one think that something remained in the auto to ferment. As an absorbent heater core allowed coolant in the passenger compartment, the coolant then disappears; it rises in the air then lands on in the windows. The residue smears effortlessly when wiped. Having worked on cars, for that owner of the car, the odor could be puzzling but definitely they are going to be searching for the source. If a leaked heater is alleged, the coolant intensity may be short. That’s one sign, after-all when the coolant’s low it had to go somewhere. More often than not heater cores are situated on the passenger side from the vehicle. So next inspect the carpet by pulling it back and searching for coolant. Resolve if it is coolant (signifying a heater core leakage) or if it is plain water (signifying a stopped up or leaky evaporator drain.

Air Conditioning

When the heater core isn’t dripping and there’s no sour or sweet odor, the haze could just be caused simply from high humidity. The higher humidity the more likely the windows will fog up. When it rains, there’s far more humidity in the air so it is most likely that moisture can create on the windshield. A working AC program removes significantly from the moisture in the air. The main windshield defroster removes vapor swiftly in huge part because of the AC program. Even when the temperature control is placed to warm, the air conditioning compressor continues to be pumping refrigerant through the ac components and also the program is working to help remove the moisture. It does this by passing the air by way of the evaporator core; the moisture grips towards the chill evaporator and drains from the automobile through a tube in the bottom from the evaporator case. Therefore if the AC isn’t working properly, the defrost won't work also to eliminate moisture and defog the windshield.
