I am still having trouble with the side windows in the cab over (not a wraparound) I resealed them properly (removed, cleaned, butyl tape, re installed) I got a good "squish" of butyl around the outside. The seam is good, the water seems to coming in from the place that the window slides. Any advice? I'm super frustrated. I haven't been able to find any drain holes, is that my problem? I'm planning on further investigation today, but would love some help! Thanks.
