I have a 91 Explorer and the moon/sunroof leaks a little, and the passenger side rear window, not the one in the door, leaks too. i know the side window bolts in, just wondering how difficult it is to do these two things.
The rear window should be easy.Its held in by 10mm size nuts.Be careful prying the window out.It should be pretty straight forward once you get it out.Tighten nuts evenly and do not overtighten or you will make very many little pieces.
Before you go tearing things apart,check the source.For the side window,place a dollar bill between the glass and the weatherstrip,latch the window and pull on the dollar.there should be some drag when pulling.Do this at several locations.If the window is leaking from the rear section,remove the latch and add a shim between the latch and the body.This should tighten up the window.when done water test the glass with a garden hose to confirm the repair.
As for the sunroof.A sunroof is a controlled waterleak.No sunroof is water tight.They all let water in,thats the purpose of having 4 drains on the sunroof tub.With the sunroof open take a cup of water and slowly pour in each corner.You should see water leaking from behind the fron wheels and just infront of the rear wheels.If not check the drain hoses.
