The window may not leak but water can still find it's way in there and be trapped. Seen it before in the wreckers.

Don't use any sealant at all if you want, however it is against the advise of the Ford Service manuals.

The question was about the slider glass with a frame around it,not the solid fixed glass. A lot of them are installed after the trucks were bought new by the owners or other glass shops. The solid fixed glass ones I have removed normally have a little sealent , but not much . Sometimes they are sealed completly around with silicon,which means you can't get it out without damage to the seal. I won't try to out guess ford motor company . I just know I have not had any problems with water, maybe it's because we only have a yearly average of 10 to 20 percent of humidity here where I live. I would seal only for a little more security ,not water.
