Need help with defog my windshield !!

Need help with defog my windshield !!

Yes ! A/C was on
Yes ! Recirculation was off

All the way turn to windshield air . But still cant get defog , had to use windshield blade to get it clear and was alot of water outside !!

Humid is high in my area and was hot after rain ( Houston area ) . I have no idea how can I defog , any help will be appreciate !

 

I had this happen last night, I just cranked up the heat while on defog and it cleared up after a few.

 

so it was fogging on the exterior of the window? Defog wouldn't work but wipers would? Thats a temp/humidity gradient issue not defrost issue. Happens now and then, use wipers til temps start to equalize.

 

How do I clear foggy windows when it’s hot outside?
Unlike foggy windows caused by cold weather, hot weather fog forms on the outside of the car’s windows. There are some simple fixes to this problem.

• Turn on your windshield wipers. Simply by turning on your front a rear-window wipers, you can wipe away the condensation and see much clearer. While this tip helps you to see out the front and rear windows, it does not eliminate the problem from side windows.
• Lower your A/C, or turn it off completely. Increasing the temperature in your car balances the temperature difference between the inside of your car and the outside air temperature. This will stop condensation from forming. You are usually able to prevent condensation without turning off your A/C completely.
• Keep your recirculating air feature off. Again, turning off your air recirculation will help correct the problem.

Don't use your air conditioning on the defrost vents your only cooling the windshield and generating more moisture.

 

Thank you y'all . You are best

 

Make sure your cab air filter is clean too. At least if any of that is on the inside.
