Hi espods. Welcome to the forum. If this has been happening for quite a while and has been getting progressively worse, try using Silicone Spray Lube on the front and rear rubber channels. That stuff will make the glass slide much easier and will leave a lubricating film behind after evaporating. I use the stuff from the Dodge dealers but you can find it at auto parts stores too. This is especially likely to help if the window moves faster if you help it by pushing or pulling on it.
When the motor struggles with the window and runs slowly, it will draw higher than normal current. Most window motors have a thermal cutout that resets automatically when it cools down. Those cutouts often develop pitted contacts that restricts sufficient current flow so the motor runs slow.
Another place to look is for frayed wires between the door hinges. Two wires go from the passenger's door switch, through the hinges, through the driver's door hinges, and to the driver's master switch. Frayed wires that affect just the one window could be found at either door.
If you think the problem is with the motor, you'll need to remove the door panel, then measure the voltage between the two motor wires when it is trying to run. If you find full battery voltage, suspect a defective motor. If you find significantly less than battery voltage, you'll need to work backwards toward the switches to find where voltage is being dropped across a bad connection, frayed wire, or burned switch contact.
