It could very well be torn vapor barrier. If you had window regulator problem in the past, the vapor barrier had to have been removed.

To see if that's the problem you could leave your rear door open and pour water over the outer window trim part. If the vapor barrier is torn, then you will see water dripping down between door panel and inner part of door. If that's the case, open your door panel and re seal the vapor barrier.
