My rear tailgate window will not open

several things come to mind, how long since opened? if very long time might be latches rusted up, other is that connection inside has come loose. remove the inner liner of tailgate and look inside and try pulling the latch rods by hand and free up tailgate. fix rod if disconnected and /or clean latches with wd-40 and brush, spray clean and spray with lithium grease.

i have 99 blazer did same thing took panle off tailgate wire came off window latch put it back on been fine ever since

pop rear land rover logo off tail gait latch and works handdle back and forth with some spray lube. should open up.

Do you live in a dusty area? My sister lives in dusty New Mexico and had a malfunctioning XUV tailgate. My reasoning was that something must tell the tailgate not to drop down if the glass is up, and if it can't tell, then it will only open sideways.
So we removed the trim panel, and the tailgate was indeed full of dust. By reaching my arm in, I found two plastic optical sensors which tell the gate whether the glass is up or down; both were coated with dust. After cleaning these the tailgate was back to its normal operation. The two sensors are flat, round - about the size of a nickel or dime...I couldn't see them, just found them by guessing that they must be there. Hope this helps!

its a linkage problem . you need to remove the door panel to repair

I had the same problem. I was able to get the back window open.
I took the the 4 screws off that are on top of the inside of the door (where the tailgate window latch is).
Got a metal coat hanger. straightened it and made a hook at one end.
carefully pushed the plastic part of the tailgate towards the inside
slid the coat hanger straight down (to the level of the tailgate key/handle) to catch the door latch from the inside and pulled up.
that will get the tailgate open.
then you need to take the rest of the screws out of the lower part of the tailgate to get at the latch assembly. Carefully take the plastic off.
(you will need to take the nice black insulation stuff off the metal part of the door carefully so you can replace it and tape it up if necessary after fixing the latch.)
peel the insulation off the metal part of the door, you will see the assembly rod has come off the latch and will need putting back in place and a little sqweeze to stay on.
really bad design I guess, but since I fixed it at 140000, I haven't had any trouble with it at 166000.

if you take off interior panel.....push out the dent with a bar....then try button if no work go back inside and you should see bars going down from handle to latch area...pull up on it and should pop the trunk

if there are no broken wires inside the tailgate try lubing the latches with WD40 and open and close the tailgate several times. If the latches are properly closed on both sides the window will not work

The rear window has to be completely down in order to move the tailgate! You should be happy that your window is stuck up, unlike mine which is stuck all the way down! I have to completly take apart my tailgate!! If you want to try a trick to get the rear window down, my bronco has a rear window switch right next to the headlight knob, take the 2 purple wires on that window switch, and cross them, if your motor still works and if the wires are good, that should make the window go down!!! good luck, hope that helps!

the actuators have a white stem that sticks out of the bottom of them. if you push up on the ones on the driver side it will open the back hatch for you.
