The power windows on your vehicle are controlled by an electronic control module , as are the power mirrors !
Power Window System Components
The power window system consists of the following components:
• Driver door module (DDM)
• Passenger door module (PDM)
• Body control module (BCM)
• LR power window switch
• RR power window switch
• Window up and window down relays in each of the rear passenger window switches
• Window lockout switch
• Reversible power window motors in each of the doors (circuit breaker protected)
• LT DOOR CB 25A (System power for left rear window)
• RT DOOR CB 25A (System power for right rear window)

Your best bet , take your vehicle to a qualified repair shop.

1 Open the door, place the blade of the screwdriver behind the lock switch on the door panel and pop it out of the door panel. Repeat this process for the trim panel around the power window switches and the interior door handle, pulling both of those pieces off of the door.
2 Unbolt the door panel from the door using the 3/8-inch ratchet and socket. There are bolts behind the door lock and in the corners of the panel. If this is a front-door panel, pull off the triangular panel that covers the mirror bolts using your hands. Then lift the door panel up towards the top of the door, and then pull it off the door.
3 Plug in the window switches again to the harness on the door. Roll the window down halfway until you can see the bolts that clamp the window in place through the access holes. There are two 10mm bolts that clamp the window to the window track, and there are access holes that allow you to unbolt those clamps using a 3/8-inch ratchet and socket. Unbolt the clamps at this point
.4 Pull up the rear of the window--the section toward the back of the Tahoe--and tilt the window up so that it is oriented perpendicular to its normal position. Pull the window out of the door panel, tilting it in towards the interior of the vehicle.
5 Slide the replacement window in place in the same manner you pulled out the stock window. Tilt the window back into the clamps, then loosely tighten the clamps in place. Roll the window up and down a few times to make sure it fits correctly, then tighten down the clamps on the window using the 3/8-inch ratchet and socket.
6 Reassemble the door panel in the reverse order of dis assembly.

You need a new window lift motor.

If the window motor still runs (assuming that they're power windows) press the button like you're winding up the window and have someone else pull the window up by pressing havnig one hand on one side of the glass and the other hand on the other side with the door open.

It may be that it is not on the track properly or your power window motor is old and tierd and can take the window down but it doesn't have the juice in it any more to bring it back up. replace the motor and it will work. This problem happened to me in my '76 ford ltd and a new motor fixed it.

get it to the dealer asap.

you definitely need to take apart the door. There's something not right inside.

Same problem on passenger door 92,000 miles. Dealer said he can reset the regulator inside the door by pressing button. I am looking for more information on this problem too. He estimates 1/2 hr (~$50) to do work.

1. Raise and support the rear door window glass to the full up position.
2. Remove the interior door handle.
3. Remove the rear door speaker.
4. Remove the water shield.
5. Disconnect the rear door window regulator motor electrical connector.
6. Remove the rear door window regulator rivets.
7. Remove the rear door window regulator by sliding the regulator arms off of the window glass track.
8. Installation is the reverse of the removal procedure, noting the following:
   • Cycle the door glass to make sure of engagement of the drive mechanism.
   • Remove the rear door window glass-to-regulator bolt or rivet.
   • Position the rear door window glass as necessary to access the rear door window glass-to-regulator rivet.
   • Secure the rear door window glass in the full UP position with tape.
   • Disconnect the window regulator motor electrical connector.
   • Remove the 2 window regulator nuts.
   • Remove the 3 window regulator motor bracket nuts.
   • Install the window regulator assembly. Tighten the 3 motor bracket nuts to 89 inch lbs. (10 Nm).
   • Install the 2 window regulator nuts. Tighten the nuts to 89 inch lbs. (10 Nm).
   • Connect the window regulator motor electrical connector.
   • Remove the tape securing the rear door window glass in the full UP position.
   • Position the rear door window glass as necessary to access the rear door window glass-to-regulator rivet. Tighten the bolt to 62 inch lbs. (7 Nm), or install a new rivet.
