Hi, I purchased a new 2007 grand cherokee almost a month ago and the windows have a condensation problem that I can not figure out, I have taken it to the dealer a couple of times and they have checked the temp at the vents and the moisture coming from them and everything is ok, I'm wondering if there is a bad seal somewhere letting in moisture. Any feedback would be helpful at this point.
Thanks.

Do you have a Laredo, Limited or Overland? Is it condensing on all windows or just side windows? What is the temperature outside when it happens? What are the heat controls set at? I got a Limited 2 months ago. With the automatic climate control on, cold temps outside and plenty of snow dragged in on my feet, jacket, etc. I’ve noticed condensation on the side windows. I either ignore it and it eventually goes away or I turn the system to defrost.

WKJeeps mentions this at the bottom of the automatic climate control page, so for what ever reason, it must be common. I suspect that in “auto” mode it is re-circulating some portion of cabin air while in "defrost" mode it will pull 100% outside air. But I hope I never have to learn that much about the HVAC system in the Grand...

It is a laredo, and the problem seems to be mainley the side windows but the windshield will do it if you don't run the defrost, the temp outside is between 20 to 30 degrees, There just seems to be alot of moisture I have owned several vehicles and never came across this problem before.
Thanks.

Depends on the outside humidity, when there is inside condensation, I run the a/c with the temperature up and it clears it. Seems to happen on those cold rainy mornings.

Thanks I'll give it a try

I was pleasantly surprised by the lack of fogging on my 08. Our old Durango's windows fogged up every winter morning (temps usually in the high 20s to low 40s) and I've only had to turn on the defroster one time when it was raining pretty hard.

Condensation is a combination of Dew point and available water vapor.
Dew point is obvious, low temp outside, high temp inside. The window glass is cold and water vapor will condensate.
Normal amounts of moisture will be handled by the ventilation system.
So that leaves excessive moisture or inhibited ventilation.
Check all the carpeting for dampness.
Make sure that you don’t have your heating system set on recirculation.
