I'm having this problem during cold days (~10-15F)
Thin ice is forming on the inner side of the front window, which fog the car real bad
so I have to clean the window using de-icer and a cloth. It happened 3 times the past 2 weeks, I checked all my windows and doors before and it's all shut,
do this happen to any people?

 

My guess is that your A/C is not removing moisture from the inside air. (In case you weren't aware, the A/C will be running to remove moisture even with certain heat settings.) Sounds like you may have the controls set to recycle air which will tend to result in a buildup of moisture in the inside air. (Make sure you have the air source switch set to outside air.) Then when the car sits in sub-freezing temperatures, the moisture condenses out and can freezes on internal parts of the car. Either that or you have a source of moisture (heater core leak?) in the car or the heater controls are not set correctly to allow the A/C to remove the moisture in the air.

You might want to review the owners manual just to be sure the A/C is on when the controls are set to the heater settings you're using.

 

Your problem is a symptom of moist air being recirculated in the cabin, and condensing on the inside surface of the cold glass. The solution is to either heat the glass, or dry out the air inside the cabin - the manual is your best bet in this case.
