When I removed my dew wipes, ther was no way I was geting the screws out with a pair of pliers.
I had direct access to the screws with a straight screw driver and STILL couldn't get them out, they were in there good.
I ended up having to drill the damn things out, and replace them. Rather than buy the tool, there is quite an easy way.
If you remove the inner door panel and the end brackets,etc, you will have access to some of the screws. If you then remove the window stops, you can roll the window up further to access another. Then if you gently pull up and forward on the glass, it will remove itself from the track and you can get under the window to access the remaining screws. Thats how I had to do mine so I could get a drill in there. There is a more indepth article of the method I mentioned if you run a quick search. It only took me about 30 mins to do both this way though.
