Hi everybody. I have a 94 ranger 4.0 with 195,000 miles, and I have a bad problem with the windows fogging up. Nothing I do seems to help. I tried window anti-fog fluilds, cloths, and yes the defroster also. Sometimes as the engine is warming up for the 1st few miles I get steam out of the vents. Anybody got any ideas or answers? Any help at all would be appreciated!
Merry Christmas & Happy New Year!

Sounds like the heater core is leaking.

 

yeah it sounds like youre getting some fluid in the vents making tons of humidity

 

99.99999% of the time, when you keep having that problem it means you have coolant in the air... do you smell any coolant??

 

If it has a sweet smell to it, heater core time.

 

I love the smell of burning atifreeze in the morning!

 

I had a 06 ranger that did that so bad especially when it was raining I would have to pull over or stop where I was and wait for it to go away. I took it to the dealer and they said nothing is wrong.

 

It sounds like a bad core to me too. If you don't have a bad heater core then does your A/C compressor come on when you put the heater control in the window defrost position? The A/C is supposed to work in defrost position to remove moisture from the windows and inside the cab. The A/C in conjunction with heat cleans the windows off.

It could be low on freon, bad comp., bad clutch, bad selector switch, etc. Your going to have to do some trouble shooting to find the problem.

 

My Truck (07') windows fog over all the time but when I turn it on defrost it cuts it out. I have wiped my windows down and tried cleaning them but it still does it. It doesnt do it all the time but when it does, I just turn it on defrost and it knocks it out in no time.

Good luck with it man
