I went to get into my new Express Cargo AWD and the whole roof was wet. The headliner was so drenched my dash was wet, and my cup holders were filled to the rim with water. I brought my car up to the dealership for inspection, and they told me that it was condensation build up which was normal in the rainy season. They said to expect it to sweat in the summer, and that I must dry it out daily to prevent it. It’s not an easy chore to just keep it dry. It took almost 4 days to dry with heaters inside the car. After it’s dry and I go about my business then park it the inside is soaking wet again. What could be the cause of this and how can I stop it?
Hi! I assume that the problem you're having is with the drains under the windshield wipers being clogged and unable to release the water. It would make sense because, if the drains are clogged by the windshield wipers, the water would have leaked by the front dashboard and will likely end up in the cup holders. The best way to check if this is happening is by removing the windshield wiper arm assembly and the plastic cover to access the drain holes.
I'd recommend having the vehicle inspected by a certified mechanic, such as one from YourMechanic, as they can help you pinpoint the source of water.
