Possibly stupid question, tread lightly

[Mudder]

I have a possibly dumb question but recently I’ve wondered so thought I’d ask. My truck sits outside and on mornings where it has frosted over or iced over and I have to defrost the windshield etc I am getting a ton of moisture and condensation on the inside of the windshield. Enough I have to wipe it off to see. Is that normal? I’ve had other vehicles that sat outside and I don’t remember that from them. Should I check seals or is it just the size or what?

My 02 did that years ago. Turned out the 3rd break light was leaking. Underside of carpet was soaked. Had to take it out and let it dry good. And fixed the light. Just someplace to start

My heater always has a slight coolant smell to it and my RAM is quick to fog windows, but I have no leak and no wet carpet.

I’ve dealt with the 3rd brake light leak before but have switched lights and hoped this new gasket was ok. Guess I’ll have to redo it and see how it goes.

Feel around the floors for wetness. Shouldn't be there...

Yup. You have a wet vehicle.

Even water on the floor mats will do that. I live in a humid environment so it does that any cold morning. Defroster evaporates it pretty quick once it's warm, but occasionally I wipe it with a paper towel to speed up the process. If you have rubber mats it's a good idea to take them out on a warm day and let the carpets dry.

I live in Arkansas. It’s pretty humid. And I do have the rubber mats. In the past when the 3rd brake light leaked I could feel it on the seat and headliner.

You could also check your door seals.

Everyone covered the basics of door seals and third light. Maybe go find yourself and dehumidifier that runs on batteries and see if it helps.

Use is high quality window cleaner and clean the windows really well. I just detailed my truck yesterday and this morning my windshield was clear. I notice after a bit it gets a film on it. A good cleaning takes that away and maybe less for moisture to cling onto

My two cents [emoji6]

Maybe teenagers are making out in it at night. Set up a camera.

I live in Arkansas as well and if it's any consolation... my RAM has had moisture inside and my work car is a 2017 Kia Forte and it's been just as wet inside. This winter has been really wet.

Maybe the cabin filters are getting saturated and evaporating into the dash ?

Mine did that but thankfully i realized it was the third brake light quickly before a lot of damage could be done. I would look there.

 

[mowin]

Do you have the defrost on fresh or recric?

 

[Mudder]

I think I had it on fresh

A few weeks back had a number of days of rain and above freezing temps and just getting in and out of truck left a lot of moisture on the mat. Temps dropped to around freezing one night and had inside of windshield coated with frost. I just let defroster do its thing and once the interior dried out a bit everything was back to normal.

Obviously you are experiencing moisture build-up inside the vehicle. Leaks, of course, are often causes, but the ambient air humidity should be monitored to determine if environmental conditions are in play. For example, on rainy overnights in the summertime I get the same symptom. In the wintertime if my floor mats or carpet collects too much water I'll have the same thing. Parking on an incline may have an effect if water builds up in the cowl and doesn't drain out. In fact, on my Dakota the cowl drains got clogged by house roofing material once and I had a severe case of moisture build up in the truck.
