Question: 3 out of 4 power windows stopped working, what could be the cause?

Our bmw windows stopped working recently. The front driver side window works but the other 3 stopped working. When you try to roll down the front passenger and rear drivers side windows nothing happens, no noise no movement. When you try to roll down the rear passenger window, it makes a repeated clicking noise, but the window doesn't move. the lights don't dim or anything when you try and roll down the window. I am trying to figure out why the windows aren't working, and what caused them to stop working, so I can get fixing them. Any suggestions?

Did they all quit at the same time? Because it sounds like you've got a couple of different issues.

The rear passenger window sounds like it has a bad window regulator. Since the switch is getting the motor to move, the electrical side of the circuit is fine.

For the front passenger and rear driver window, the problem could be electrical. Check the fuse and the switch. If you have power leaving the switch, check the motor.

Thank you for the response. I checked the fuses and found that one of the window fuses was blown, when I replaced the fuse, all the windows, except for the rear passenger window, are working. Now it is just the rear passenger window, the one that was clicking, that doesn't work. You said that it might be that the regulator is bad. what is a best way to check if the regulator is no longer working?

You need to remove the door panel and physically inspect it. Here's the instructions:

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
