Ok I am getting tired of this but does anyone have any idea why would my car fog up overnight and have moist inside. I mean it takes me 30 mins to defog it and I just use a spare windshield wipper to whipe inside and there is so much water...

I have noticed its just my millenia since the other 2 cars are normal and if they do fog up they don't have moist inside.

I have tried to turning it to close it so the outside air doesent come in but it doesent work, I have tried many things and nothing worked out for me.

Also my heater has loss power which when I turn the fan to the high it is not high belive it or not but its not blowing enough.

Does anyone have any ideas, I know this is the best place to get information

 

Check the carpets very carefully to see if any are damp. Excessive moisture on the interior windows in the morning is almost a sure sign of a water leak into the interior of the vehicle. Don't forget the trunk and tire well also. My 323 has a little leak at the tail light gaskets and my windows are sometimes so covered with interior moisture that I use a squeegee to remove after a good rain.

 

Scouter: don't know how old your message is, but my thoughts are that the AC isn't drying your vent air enough. On defrost, your AC unit dries the air so it doesn't fog up and if your AC doesn't work then it can't pull moisture out of the air. Shouldn't have a lot to do with fan speed I don't think. More with either wet carpet or A/C problems. Good luck.
