Looking at a 2015 EL and noticed that when the rear quarter window is open, it is pretty easy to flex the window, especially at the top. Kind of flimsy.

2 questions.....

Can the vehicle be driven with the rear quarter window open?

If so, do they vibrate?

 

I've had absolutely no problems with mine. I have driven with them open at highway speeds.

 

Thanks.

My concern was them flexing enough to "pop". Really seems like it should have been designed with two "posts". The one on the bottom and another up near the top.

I will be putting a cage (divider) in back of the 2nd row and needed to make sure I could drive with them open so my dogs can get air.

 

Ford's been using a similar system in the Navigator since at least 2000. We had one and it worked great. It only had one motor/linkage and never gave us any problems. Those were similar sized windows to the Expedition. And while I haven't put lots of miles on my EL, those windows work well even in strong winds.

 

no problems....

 

since 1997

 

Both quarter window actuators are actuating fine on my Excursion (for 16 years). And those are big windows, too!
