how do you guys clean the rear window in front of the third brake light? I was getting the grime off mine this morning, and noticed there's a small space between the two. ideas?

I have not tried this, but I would be willing to say that the High Mount Brake Light probably pops off some how.

After doing some searching:

I found that you can pop a cover off of the High Mount Brake light in order to change the light bulb in side. I might think the best thing to do is maybe slide a thin layer of paper towels between the window and the light. That may be the only way to go. I dont know.

Yeah,just pushing in those small tabs on the sides releases the cover.If you want to make sure you get it nice and clean behind the there,just remove those two 10mm bolts that hold the rest of the unit in place.:)

Update: Yesterday while changing the high mount stop bulb,I found a little trick that makes removing that cover quick and easy,all you need to do is take your thumb and fore finger and squeeze the center of the cover and just pull it straight off.:)
