A power window that stops halfway is almost always a worn motor or a regulator that has lost grip on the glass. The good news: you can usually nudge it back up by hand and limp home. Here is what is wrong and what it costs to fix.

Motor brushes are worn down. The motor still spins on the easy direction (down) but stalls partway when fighting gravity (up). Tap the door panel near the motor while pressing up - if it moves a bit more then stops, brushes are the cause. Cost: $200 - $450. DIY: Medium. Severity: Low.

On the driver master switch, look for a small "lock" or "child window lock" button. If it is engaged, the passenger and rear windows cannot move. Press it off and try again.
Open the fuse box (usually under the dash or in the engine bay). Locate the "Power Window" or "PWR WINDOW" fuse - typically 25-30A. Pull it and look at the metal strip across the top. A broken strip means a blown fuse. Replace with the exact amperage printed on the fuse.
With the door panel off, locate the window motor (round can-shaped piece bolted to the regulator). Apply 12V from a battery jumper directly to the two motor leads. If the motor spins, the wiring or switch is at fault. If it does not, the motor is dead.
Sit in the seat. Hold the switch UP for 3 seconds after the window stops. Then hold it DOWN for 3 seconds after it stops. Repeat 2-3 times. This re-teaches the controller the window's travel limits.
If your scanner shows one of these B-codes (body) along with the symptom, run a free AI diagnosis to confirm.

Sometimes. Slap the glass with flat palms and lift evenly with both hands. If the motor is dead but the regulator still grips, you can usually get it up and tape it in place until you fix it.
The auto up/down controller has lost calibration. Reinitialize by holding the switch up for 3 seconds after the window stops, then down for 3 seconds. Specific procedure varies by make.
$200 - $500 at a shop including labor. DIY parts run $80 - $250. The most common fix is a motor-and-regulator assembly, which takes about 60-90 minutes per door.
Yes, but it is a theft and weather risk. Tape plastic over the opening for rain and park in secure spots until repaired.
Gravity makes "down" easy and "up" hard. Worn motor brushes can deliver enough current for the easy direction but not the hard one. Replace the motor.
Only if the auto up/down lost calibration after the old battery died. A weak battery itself rarely causes window failure - the motor draws current for only a few seconds at a time.
