It's also possible that the problem is deeper inside the door. If so, you'll need to pull the door panel and go poking around. Remember to pull the fuse to prevent amputating your fingers. You can use either a rubber wedge doorstop or a couple of feet of duct tape to anchor the glass up while you work. Sometimes the problem is nothing more than a loose bolt allowing the door's inner structure to move around, misaligning the window track.
All bets are off if the door has been damaged in a crash. It may take a long time to get everything working right. Lastly, the mechanism that runs the window up and down may be faulty.
Whether it's a gear-and-sector, scissors lift or cable-operated mechanism, you'll need to watch it moving up and down a few times. Again, keep your fingers out of the works. Sometimes the problem will be a loose fastener or rivet, sometimes a broken or missing bushing.
Cables can bind on the drum or become sticky. Lube all the friction points with white grease. Don't forget there are gaskets in the window track down below the top of the door, and you may need to reglue, repair or lubricate them.
It may be possible to replace a bad motor, or you may need the entire mechanism. Check the weatherstripping and window channel for torn, loose or folded rubber parts, or foreign objects in the way. Some late-model high-end cars have frameless windows that automatically crank themselves open a quarter-inch or so as the doors are opened. It happens so fast that you may not notice it.
The window opens rapidly, clearing the seal before the door latch clears. It then closes automatically about a second after the door latch latches. There are two advantages to this. First, the slightly open window vents interior air, which can actually make doors on tightly sealed cars hard to open by springing the door back open against air pressure. It also lets the manufacturer use a vastly different style of seal on the top of the window.
The seal can more closely resemble a sedan door seal, with a small lip protruding over the top of the glass. This type of seal won't work on frameless windows because the glass has to clear the seal as it opens and closes. This type of seal allows less water and noise intrusion. The downside is with the logic control module needed to achieve this. Repairs will probably need a factory shop manual and, potentially, some expensive parts.

Recent Window Switch is not working Inspection reviews. Excellent Rating. Rating Summary. Whitney 39 years of experience. Request Whitney. BMW Ci L Always friendly and comprehensive. Whitney is awesome! He diagnosed my problem within about 2 minutes and set a plan to fix it.
I was able to watch him work, so I increased my mechanical knowledge as well. I will never use another mechanic service again! I finally found a mechanic who I trust and who makes it super easy for me, all a better price than any shops I have been too.
Mark 11 years of experience. Request Mark. Ford Explorer V This was my first experience with YM and I could not have been happier. Once I found YM on-line, I scheduled an appointment which was simple and quick.
From that point forward, Mark took over and did everyhting he said he would do that is a rareity these days. He was punctual, detailed, thourough, and an excellent communicator. Mark was very punctual and thorough. He came back because he wasn't completely happy with the first OEM part window regulator that he received after installation. He went an purchased a new part from the BMW dealer and reinstalled the new part.
Highly recommend Mark for his knowledge of BMWs Scott 36 years of experience. Request Scott. Toyota Tacoma V The switch is wired to the battery the vehicles electrical system. The window lift on most cars uses a linkage to lift the window glass while keeping it level. A small electric motor is attached to a worm gear and several other spur gears to create a large gear reduction, giving it enough torque to lift and lower the window.
An important feature of power windows is that they cannot be forced open. Worm gears have a self-locking feature because of the angle of contact between the worm and the gear. The worm can spin the gear, but the gear cannot spin the worm — friction between the teeth causes the gears to bind preventing it from moving.
The linkage has a long arm or cable, which attaches to a bar that holds the bottom of the window. The end of the arm or cable can slide in a groove in the bar as the window rises.
On the other end of the bar is a large plate that has gear teeth cut into and the motor turns a gear that engages these teeth. The same linkage is often used on cars with manual windows but instead of a motor turning the gear the handle turns it. The power comes into the window-switch control panel on the door and is distributed to a contact in the centre of each of the four, or two depending on the type of vehicle window switches.
Two contacts one on either side of the power contact are connected to the vehicle ground and to the motor.
