Question: "There is heavy condensation in my car and a damp smell. Today I found the carpets are wet. I went through a car wash and didn't see anything leak."
Answer: It's very rare to be actually able to see the where the leak is coming from without taking parts of the car apart. Leaks are sneaky, they find the smaller holes to get in and dribble down the backs of panels until they fill up the floor pans and make your carpets wet. We begin by checking our database, looking at all the usual places we know cars to leak. We usually have a pretty good idea where a leak is before a car gets to us, but we have to check everything anyway, every car is a bit different, especially those that have been involved in accidents because a crash can open up welds and seams.
