There's a safety feature in the tailgate that won't allow the glass to go down if the tg isn't shut firmly. Cgeck that the strikers are not worn out or the latches aren't loose, and try pushing in on the tg as you try the key switch. But if the motor doesn't spin with 12V power, it's toast. Same for the door motors. IF they spin but the glass won't move, the tiny gear drive can get stripped and can be replaced alot cheaper than another motor. Also, checkt the condition of the side felts or glass runs. I sprayed some WD-40 on mine to clean out some of the dirt and grime that kept the glass from moving very fast or not at all. JSM84

Here is a picture of the package noted in the forum. If the motor is working, then this should fix the problem.
