Well it was a fairly brisk morning here in northern Illinois this morning and I fully expected to have to scrape a thin layer of ice of the windshield this morning. What I didn't expect was to have to scrape it off of the INSIDE of the windshield. In all the cars I have owned in the past this is usually caused by damaged door seals, but I thoroughly inspected the seals and found nothing. Anyone know what might be the cause of this on my 06 XLT?

 

I have the same problem with my 05.

 

My guess would be the new electronic valves for the hvac one might be bad and is leaving a door open allowing outside air to get inside your truck.

 

Would this be the blend door motor? Or are there other ones and if so where are they located?

Thanks for any help

 

I had a little but in Eastern Iowa but it went away after about 2 minutes of defrosting

 

Where in Illinois? I'm in the Elmhurst area

 

There are a total of 3 i think

Blend door
One to open outside or inside air
And one for setting.

 

Sycamore. Where are said doors located.

 

All my vehicals have done that from time to time in the past. I find normally when it happens the air inside the truck was quite humid when it was parked. So when it freezes all the moister turns to ice. That's always been my problem most times.

 

I just had the windows tinted so I was wondering if the moisture from that was the cause.
