Very typical for the window motor to fail. The tailgate will not open when the window isn't rolled down. If there is voltage to the terminals of the window motor when you actuate the switch but the motor does not turn, replace the motor. Once you are able to roll the window down, the tailgate should open again.

This video should solve it. If the window is not dropping enough see the video at about time 4:10 where a problem causing this can be seen followed by a solution. https://youtu.be/xLQOzLaq5mw

Got the problem fixed..tailgate was jamming..thanks.

No there is no bypass. The Motor in my tailgate crapped out on me last year partly to do with a rusted out tailgate that let water in! I replaced my tailgate, but in my research found that the only way to get the window down was to remove the inside panels on the tailgate, un screw the cover plate, and then unbolt the motor to allow the window to drop enough to open the tailgate. Once the tailgate is down it will be easier to see the internals and remove the motor. Hope this helps you

Remove the interior trim panel which will not be easy since the gate is up ---- you can then access the lock mechanism and will probably find a bent linkage rod or a broken plastic retainer clip.

open the tailgate... pull the window up with your hands, and take out the gear. its a round plastic gear and i had the same problem... mine was completely shattered and its about 12 bucks to replace

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

There is a saftey built into the tailgate that will interupt the ground to the switch in the center console with the tailgate open. This keeps the operator from trying to roll the window up with the tailgate open. If you have no ground to the rear window switch it is most likely the tailgate safety switch. If it is like my '88 it is built into the drvers side tailgate latch.

I believe you have to open the rear window to open the tailgate??
Tailgate opens right to left [ passenger to driver ] side?
Tailgate handle will not work if window not open - feels like it is disconnected. The "button" releases the window only.
If you open the rear window and the tailgate still will not open. You need to remove the inside tailgate cover to get access to the handle and release switch. You can access the the window release the same way [ just a little harder to do]. You will probably end up breaking the vinyl panel to do this but so will the auto body shop and they will charge you $$$$$ to replace it.
