This can be caused by a number of things, including a communication error between the window motor and window button. Other reasons for a failing power window in a Mercedes are faulty wiring, malfunctioning switches, and overheated window motors.
If all your Mercedes-Benz windows have stopped working, first check for a blown fuse. If your Mercedes-Benz doesn`t have fuses for the window, check fuses for the door module. Also, check the master switch in the driver`s door. If the master switch is defective, it can prevent all windows from working.
The most common reasons a Mercedes-Benz C300 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.
Window malfunctions are typically caused by a faulty window regulator (also called a window track), or a broken motor, cable pulley or window switch. Sometimes it can be a combination of those things.
A dropped window is an indicator of a bad, disconnected, or misplaced balance shoe. Each double-hung window in your home has four balance cartridges, two per jamb liner. If one of the balance shoes inside isn`t working properly, the sash will slide down when you attempt to raise it.
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.
If you can log in, press Windows + R and type cmd. Then press Ctrl + Shift + Enter to launch Command Prompt as administrator cmd. Type systemreset -factoryreset on the Command Prompt and press Enter. You`ll get a choice to keep your files or remove everything.
Collapsed glass is a problem that occurs when your dual pane windows start to leak. Double-paned windows are made with two pieces of glass. Between those two window panes is a special type of gas, usually Argon, that is used to provide insulation.
You can expect to pay an average cost of $100 to $400 to replace your windshield, a side window, or a rear car window. Classic and exotic vehicles will be more expensive. Small, triangular side windows can also be more expensive due to the difficulty of installation.
An electric window circuit

The switch is wired to the battery via a relay and a fuse or a circuit breaker. Although they can be a real convenience (no more leaning over the passenger seat to open or close the window) they can also be a considerable annoyance when they stop working.

How do I know if my power window motor is bad? If your window won`t close completely, it doesn`t move as quickly as it used to, the window doesn`t move at all, or there are strange noises or smells when you press a power window switch, the power window motor has likely failed.
Its the keyfob that is the culprit. On a normal/functioning keyfob, if you press and hold the unlock button, the two front windows will go down automatically when the keyfob is in range of the car. I do this on hot days when approaching the car to start letting the heat out.
Windows would go down unlocking the door (fob or key). Turns out they had left something disconnected inside the door. On the inside of the door, on the lock, make sure everything that needs to be connected, specially the levers connected to the locking mechanism.

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.

ANSWER : Hi there. Usually when both window switches do not work it is due to an electrical fault with the primary control module. There is a center module that relays all electricity from switches to individual window drive motors to open and close. When more than one switch doesn’t appear to be working, it typically due to an issue with that center window control module or electrical relay powering the system. It would be a good idea to have a professional mechanic come to your location and complete a window not working inspection to determine precisely what is causing this issue before attempting any further repairs.

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.

The rear window automatically comes down after closing it using the second stage on the switch.
ANSWER : Try this procedure for resetting the windows: with all the car windows fully closed, enter the car and put the key in the switch. Turn the key to the on position, but do not start the car. Lower the driver’s window fully using the first position of the switch. When the window reaches the bottom, push the switch the rest of the way down to the second position and hold it there for ten seconds.

Then, raise the window fully using the first position and, when the window reaches the top, press the switch the rest of the way to the second position and hold it there for ten seconds. Repeat this procedure for all the other windows from the driver’s control, next doing passenger’s front, then passenger’s rear, and then driver’s rear. Then, turn off the key and remove it. The next time you turn the car on, the windows should work correctly.

If not, then I recommend having a certified mechanic, such as one from YourMechanic, come to your location to inspect the windows for you.

ANSWER : The switch internals of one or both switches are faulty or there is a bad connection to the switches. To resolve this, the switches have to be removed from the door so that you can get access to the terminals.

What is causing my power window to act strangely?
ANSWER : It sounds like the window motor is approaching the end of its useful life. When electric motors age and wear, they become less efficient and less powerful. They will slow down and start to draw more current. The power window circuit is protected by a circuit breaker. Your motor when pushing the window up, is exceeding the limit of the breaker, then it opens the circuit.

The breaker only takes a second or two to cool off and resume, and then the process repeats. There are some things you can check and try. Check the rubber window track. Make sure it is in good condition. You can lubricate it with a silicone grease, like dielectric or tune-up grease. Use a small paintbrush to lube the inside of it where the edge of the glass contacts.

Clean and wax the window glass. Friction from the glass to the rubber atop the door panel can slow a window down. Window tint will also create more friction. Doing all of this before replacing the motor might be enough, but if the motor is tripping the breaker, it will probably need to be replaced. You can also try these things on the passenger side to see how much faster it will become. If you want to have this the window motor replaced, a technician from YourMechanic can come to your home or office to perform this service.
