I finally had to adjust the Passenger side Rear Window on my car. Until recently I was able to get the window to raise completely as long as the Engine was running but that stopped working. The Window would get ALMOST closed but not enough. I had to open the door, grab the front edge of the Window, and pull it the rest of the way so it was completely closed.

I took the back seat out to replace the rear Speakers and while I had things apart I diddled with the window. Turns out the window on my car was raising too far and hitting the weather-strip in the Top. See image below:

The top of the Rear glass should be the same height as the Door glass. See image below (this is the Driver's side):

There are 2 bolts that have to be loosened so you can adjust the glass. One of them is covered by a rubber plug (at least it was on my car). See image below: It's the rubber plug with the yellow stains on it.

The 2 bolts are recessed quite a ways behind the body panel. You'll have to use a socket extension to reach them. Be CAREFUL. I snagged the socket on the lip of the hole in the body panel and dropped the socket and extension down in between the body panel and the window mechanism. I was able to retrieve it, luckily, but it's VERY easy to lose the sockets down into this abyss.

This is what the bolts look like when the rubber plug is removed:

After loosening the bolts you can adjust the glass. It takes some diddling to get things sorted out. This was the best I was able to achieve with my Passenger Side Window:

I'm not sure why I can't get the top of both pieces of glass to match like on the Driver's side. It may be due to how the Rear Glass on the Passenger side is installed or the manufacturing tolerances, but I suspect the REAL problem is that the Passenger side Door Glass needs to be raised to match the height of the Rear Window Glass.

For my purposes this is good enough. I can now raise the Rear Windows with the Top Up and not have to manually adjust the glass afterwards. I don't have any water leaks so I can live with the Glass adjustments as they are now.

FYI.

I am having similar issues with my passenger side rear window. And I am replacing the speaker anyway. Perfect!

Hi Rick, very good diagnostic and repair work
Good job 👍
I have a 2017 vert and my right rear window will not quite close all the way by about an inch with the top up
With the top down it closes just fine
The left side is good, not sure if I dare mess with it, if you know what I mean....

Here ya go, I had put this together for the VERT owners a few years back…. It may help you even more - specifically the additional pdf attachment RE: just the vert windows.

Great post. I've been having a problem with my passenger side rear windows as well. I'm gonna take a look at it.

I was worried that disassembling the rear seat and trim would be insufferable and so I put it off as long as I could. Turns out it's easier than I expected. I just recently had to pull the dash to replace the Evaporator and that is a major PITA. But the back seat is easy. The trim is also easy. There are a few tricky spots but with a little patience it goes pretty quickly.

I have an electronic copy of the Service Manual I bought from eBay for less than $20 bucks. It's a digitized copy of the actual Ford Service Manual that's a LOT easier to use than the printed version. At $20 it's a steal. It isn't absolutely necessary but it helps when you get stuck.

Anyway, using the Service Manual it goes pretty quickly. It was worth it to me to get the rear window fixed. Until recently I could raise the window completely with engine running but then that stopped working. That's when I knew I'd have to bite the bullet and adjust the d#@! thing. I'm too lazy to walk around the car and pull the window completely closed every time I want to raise the window.

So don't fear it too much. It's not nearly as difficult as you're expecting. The biggest problem is finding places to put the seat & trim panels while you have everything apart.

Good luck.

I have the same issue with my rear pass. window not closing all the way. My current workaround is to unlatch the top, push up on it with my hand, and then roll the window up the rest of the way. Or, if I’m getting anything out from the passenger side I’ll just grab it and pull.

Thanks. I'm very pleased with it. The color combination was one of the reasons I purchased the car. I looked a quite a few before I purchased this one.

I tried pushing the top up on my car but I couldn't get it to work. For some reason unlatching the top seems to disable the window switches. At least it does on my car.

I'm too lazy to walk around the car to pull the window up so I tore things apart & diddled with the window until I got it to raise all the way on its own. Once I got started it wasn't that difficult. Just a nuisance.

Good on you Rick 👍 I'm always impressed by anyone willing to go where they've never gone before regarding maintenance and repair, whether it be minor or significant
Also, the beauty of that besides learning and saving money, is sharing it with others, making it easier for them to go there too
