My window will slowly roll up, but not completely.

After trying to roll the window up I tried to lift it by hand, but after raising it all the way up it falls on its own.

My car has 190000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi, thanks for writing in. The window regulator is most likely broken and no longer will lift the motor. I recommend having the door panel removed and check the window regulator to see if it is broken or the motor and regulator needs replaced. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.

Your power windows might be slow because your alternator is dying. The alternator not only keeps the battery charged, but it helps power your vehicle`s accessories and components.
The most common reasons a Chevrolet Tahoe window won`t go up or down are window`s electrical system such as a fuse or relay, a broken window motor, or a broken window regulator.
There are a multitude of reasons why your car window might not roll up, including: The fuses are blown, preventing the electrical controls handling the window from working. The child safety lock is engaged by accident. The window switch is functioning correctly, but the window motor has malfunctioned.
Clean the frames with a small amount of furniture wax on a soft cloth, focusing on the two vertical sides. Use wax to lubricate the window tracks. Slide the window up and down or back and forth a few times to allow the wax to work into and spread along the tracks.
Grip the window between your palms and slide it up.

Pressing the glass firmly between your palms, slowly move your hands up to raise the window. If there`s not much of the window sticking up, try to pull it up a little with your fingers so you can get your palms on it.

Usually, this indicates a faulty window regulator. The window regulator is the mechanism that mechanically raises and lowers the window in the tracks. Most new cars use regulators that utilize cables and spools, often with plastic parts.
It sounds like your regulator is not aligned correctly and not riveted in all the needed places. It could also be that your door metal has a crack in it, and when the window raises to a certain level, the metal in the door can`t support it and it gets out of alignment.
Here`s what to look for. When you`re cranking the window handle and the window doesn`t roll up or down, either the crank gears are worn out or the regulator is off its track. Crank gears are sometimes made of plastic that can wear down from repeated use. Or, perhaps, the regulator arm is not aligned in its lower track.
Silicone and dry Teflon are often used by car owners to lubricate the window tracks. This is because chemicals like silicone stay slick in every weather and provide long-term protection to your car window tracks.

All four windows won’t roll up or down
ANSWER : Hi there:

When you press the button to unlock the door it completes a circuit, enabling the lock actuator to receive power which activates the locking mechanism to the desired position. The circuit is routed through a door lock relay, which acts as a switch to direct the power to actuators on the door locks. In some cases, the door lock relay is what becomes damaged or faulty; which can cause the intermittent operation of your door locks as you’ve described. You might need to have your door lock relay replaced, but should have this issue inspected by a professional mechanic first to determine if the lock relay is the source of your issue.

My window on my passenger side won’t roll down and the lock button doesn’t lock the doors.
ANSWER : Hello, thank you for writing in. Your issue is most likely a switch. The window motor would not effect the door lock functions. The only true way to know is to test the power available to the switch and see if it is passing through, or making it to the motor. Where the power stops and is not utilized, is the component that has failed. If the power supply is not making it to the switch, then you have another wiring or fuse issue. Without doing some electrical testing, you may want to start with replacing the switch. For more help with diagnosis and resolving the issue, contact our service department to schedule an appointment.

My window rolls down but has a major problem rolling up.
ANSWER : The window motors can certainly be the cause of the windows struggle to go up. From age, the window motors may have worn windings and drawing too much power. Also, the window regulator or window tracks can also be causes. The window regulator can wear with age and create more resistance to lowering and rising. The window motor can struggle to overcome that resistance. Same goes for worn or broken window tracks. Unfortunately the only real way to determine which is the cause can only be determined by removing each door panel to inspect the movement of the regulators and measure the voltage draw at each motor.A certified technician can do this for you to determine the cause at each door.

Having a problem with the passenger side window switch; the window will go down but not back up
ANSWER : Hi there, this issue generally comes up often when we see a power window that does not work on the passenger switch, but still works with the driver’s master switch. It means that the passenger side window switch has failed. The fact that the drivers switch operates the window properly lets you know that the window components all function properly as that the problem is probably electrical.

A technician that is diagnosing this would use the wiring diagram to find the proper wires to test and check for power when the window is rolled up to see if there is power present when the window is commanded to roll down with the switch. Given that you are still under warranty, this scenario should be something the dealership would resolve free of charge as part of the warranty. If the vehicle is only under powertrain warranty and not the full warranty, the technicians at YourMechanic are able to provide diagnosis for your window and can perform a power window switch replacement for you if necessary.

My window is rolled all the way down and won’t roll back up. It is also not making any noise and it’s just the drivers side.
ANSWER : Hey there. This is likely a short in the power window switch or potentially faulty or pinched wires. I would suggest removing the door panel to trace the wires to the power switch to make sure they are all connected and not broken or pinched. If you’d like to have this resolved, you may want to consider having a professional, such as one from YourMechanic, come to your location to diagnose and repair your power window for you.

Power window on driver side goes down when car placed in reverse or drive without touching power window buttons.
ANSWER : Hi there. The only thing that would cause this is an electrical short, caused perhaps by an exposed wire in the power window module, which is located in the center console of your Ford Explorer. The best advice we could offer would be to have a professional mobile mechanic come to your location to complete an electrical problems inspection to try and isolate the source of this issue.

Driver’s side windows do not properly function
ANSWER : If removing the driver door window switch (or the driver-side console switch), and applying direct power to the harness yields successful operation of the window, the problem is the switch that was removed for the test. This can be confirmed utilizing a voltmeter/multimeter, and following the "power path" from the fuse, to the switch, to the output side of the switch (harness plug side of the switch), etc. A YourMechanic technician can assist with the diagnosis of your window issue and help you fix it accordingly.

How do I fix the window on the driver side?
ANSWER : Hi, thanks for writing in. It sounds like it is time to replace the motor and regulator assembly in your car. The regulator is binding and the motor has a circuit protection kicking out due to the overload. If you would like help with this replacement, consider having an expert automotive technician from YourMechanic come to your home or office to perform the replacement for you.
