I'm unable to locate a leak anywhere. I've noticed recently after a rain that the inside of the cab windows become heavy with dew as if the humidity inside is very high. A couple of times I've found droplets of water on the metal liner/skirting just inside the drivers side front and back doors at floor level. The windows are closed tightly and I've found no wet carpet areas. About a year ago, the dealer replaced the clearance light/covers on some sort of recall. Any ideas where to look?
