I have a 2003 Ex and I have not been driving it much. My company gave me a work truck, so the need to drive the ex has went way down. This is all good because it keeps miles off of it and will ultimately make the truck last longer, but the problem I have is I am noticing moisture on all the windows with it sitting. I don't have anywhere to park it inside so unfortunatley it is in the driveway. I have looked all over inside and can not seem to find any moisture on the carpets. I would assume there is moisture in the cab somewhere if it is condensating. I was thinking about buying a waterproof car cover to put on it when it is parked. What do you think? Any suggestions. Should I even be worried about the moisture?

 

running the A/C will suck the moisture out of the cabin air, I would do that every couple days. I had to do that for my 73 cause of the leaky door seals when I lived in coastal northern california to keep the moisture from building up even if it didnt rain. Check all of your door seals, maybe you need to do the door seal mod (run latex tube through the original rubber weatherstrip)
Moisture inside a vehicle leads to bad rust later on, and corrodes your electrical system, along with corroding all of the non-painted metal parts in your dash, seats, etc.

 

I had a leak in my windsheild on my Ex. Leaked into fuse box and glove box which caused weird sporatic electrical issues. Installed new front windsheild and stopped leak. Interior is now dry. Check seal above the mirror.

What is 'dirty' weather?

 

my guess would be dusty, sandy, windy weather that might blow dirt/tree peices..ect into the cowl area.

 

Ah so, Grasshopper. aka Thanks !

 

L.A. Smog

To the OP, consider one of those window mount solar vent fans. It jams up between the window and the top weatherstirp. Runs during the day to cycle the air out of the car. We used them in Arizona to keep the interior from boiling.

 

crack the windows, install a solar fan is a good idea.
A lot of waterproof car covers have another feature they don't list, they trap water in as well...so under it turns into a nice little greenhouse as all the moisture gets trapped under it.(ask my camper how I know the hard way)

 

You could go to lowes/home depot and buy one of those little jars of moisture preventer. Damp rid is the name of it. Just leave one in front, and maybe one in back when not driving it. Remove when you drive it.
