BMW OR MINI COOPER WINDOW MOTOR REGULATOR & WINDOW POWER SWITCH REPLACEMENT

You don’t think about your BMW or Mini Cooper windows until they don’t work.  Since most drivers use A/C the most common time we open the windows is to use the ATM or order at the drive through.  And then if the window doesn’t work it becomes quite inconvenient.   You might need a window motor repair diagnosis to find out if you need to replace your motor regulator, your power switch or if it is another issue that needs to be repaired.

In the mid 1970’s power windows started as a luxury feature on some cars. Now days, power windows are standard in nearly 95 percent of cars, trucks, and SUVs sold in the United States. If you want the old “crank up and down windows by hand” you almost have to special order that feature.  However the term “roll down the window” still has meaning.  So if your window doesn’t roll up or down properly, it could be the switch, the motor or the regulator, but, how do you determine which has failed?

Here are some warning signs that something is starting to fail.

These are some things for you to look for:

• It takes more than one press to roll the window up or down. This could be an issue with the switch or the motor/regulator.  It might be debris is caught in the switch and is causing the problem.
• You notice that the window rolls up slower or faster than usual. This can be an indication that a problem with the window motor exists. Windows are set to roll at a specific speed.  If this speed varies, either faster or slower, it is an indication that the motor is beginning to fail, or there is an electrical problem with the regulator assembly.  It could also be an issue with a fuse or short in a wire that is not supplying the correct power to the motor regulator.
• You notice a clicking sound from inside the door when the window rolls up or down. The usual cause of this noise is debris in the window assembly or motor.  This debris needs to be removed as soon as possible to prevent damage to the motor or regulator assembly or it might cause the window to catch and break.
• The window is crooked when rolled up or won’t stay up; it jiggles down as you are driving. When it is working properly, the window regulator assembly locks the window in place.  If it isn’t locking in place, it is an indication that you need to get this checked out before it fails.

Sometimes your car skips the warning signs and your windows stop working.

You might notice one of these symptoms:

1. All the windows quit working
2. Only one window stops working
3. Window works from master switch only
4. Windows work intermittently
5. Windows open fine but won’t close

We can troubleshoot these problems for you and get your windows working again.

The issue could be many things including:

• A loss of power in the electrical system
• A bad relay
• A blown fuse
• A failed or failing window power switch
• The failed or failing master power switch
• A bad window motor regulator

While it is thought that the most common reason for one window to stop working is the switch,  at Beyer Motor Works we will test all of your BMW or Mini Cooper window components to determine which ones need to be replaced.

Power windows are a great convenience, which you find out as soon as yours doesn’t work, but it is a safety issue as well.  If the window motor isn’t functioning properly it highly increases the chances of the window shattering or doing the dreaded “pop and drop” into the door panel.   If you suspect there is something wrong with your window components, contact us to schedule an an appointment to have it checked  by one of our professional mechanic as soon as possible to avoid additional window damage and make your next drive through experience easy as the push of a button.
