Default Re: Interior Condensation?

I was doing this as some added protection whenever I had the Crossfire uncovered to prevent any foreign matter from trees (during fall season) accumulating & potentially blocking the drains in these cowl area. I also was leaving these plastic bags in position whenever I placed the car cover back on the car.

Approximately 2 weeks ago, I took the plastic bags out of the cowling & then covered the car with the car cover. I've inspected the interior 2x in the past couple of weeks and have not found any condensation. Problem seems to be gone, and may be related to some sort of venting issue along the cowling that was blocked by the plastic grocery bags.

Any thoughts?

OK, a little help, maybe? Dry vs humid air circulates whenever there is an opening that allows it. Whenever barometric pressure climbs or drops (and moisture is in the air), that moist humid air will circulate. So, if vents are open or windows are cracked (partially open) the interior will tend to lose or gain moisture. In a garage, it'll accumulate inside the garage unless attached to a home that has a modicum of conditioning the space attached to the garage. If (like mine) it is a standalone garage, the roof of the metal garage gets wet and drips onto the car (trapped in the garage air space and the temp/humidity change outside causes it to form droplets on the interior of the garage). I digress... When a couple of cycles of raising/lowering and humid vs dry air is around a car (or truck, anything) the inside air could be saturated with moisture. Come along, open the door, you may see (or not) moisture on the lower parts of the windshield (mainly because that is the closest to the cowl where an opening is closest to the windshield). Starting the car, you tend to turn on the defroster/heat. Depending on where the dials/switches/***** are, the windows will fog up. This right here is another reason to wait until the car is warmed up (to only fight this window fogging). Normally I do not wait until the car is warmed up, only when the windows fog up to the point of limiting the view outside. IF there is a water leak into the interior, the moisture will be present every time you get in it after it sits a while (of course it is parked or left OUTSIDE, just making a point the moisture isn't there only from a change in humidity and barometric pressure). Anyway, have you ever noticed driving down the road and then turning on the heat or A/C? scary, isn't it? For those few seconds it takes the HVAC system to clear the windows, it is pretty nerve wracking. The first time it happened to me in the crossfire (only happens a little in all my other cars that didn't have a window open or a leak of some type in the body), it was shocking. Now, when in the crossfire, I run the HVAC system when first started and if it fogs the windows, I do not pull out into traffic. Yes, it shouldn't do it but it does. Know this and adjust your driving so that it doesn't happen when it is very important you need to see out the vehicle. THIS CAR DOES IT A LOT, I AM PRETTY SURE IT IS ALSO HAPPENING TO MANY MORE OWNERS HERE IN AT LEAST THE SOUTHEAST. Does this help any?
