I cannot seem to get the windshield and windows clear of all my fog,always seems to be some on the upper part of the windshield,and the back i usually covered about 75%.Defrost works but doesnt seem to clear it.Any tips to getting a clearer windshield?

 

don't use the recirculated air, crack a window or two also. i don't have trouble with the windshield, but if there is any moisture in the vehicle from snow or rain the back windows will fog up like crazy. i think rain X has something called Fog X that you can use, i've never tried it though. cracking a window usually helps the most for me.

 

i dont know, mine sucks too, make sure your windows are clean,

 

Put the heater on fresh air and open a window. Google search works well.

 

u migh have a heater core leak and blowing moisture on teh glass

 

x2 on crack a window open, I always direct my heat at the windshield also cause if there is 2 people in the truck the front gets foggy. These trucks are known for it.

 

i use fogtech i coat the inside of all the windows and have no problem. i first bought it to stop my paintball mask from fogging but since it is such a small area i decided to use it on my vehicles. i even use it on my mirrors outside. it helps deflect rain and stops frost build on them since i dont have heated mirrors.

 

Have you tried anything as simple as cleaning the inside of your windows? It seems like smoke, particles, etc makes windows fog like crazy.
