BMW 325i Window Regulator

How to Easily Troubleshoot BMW 325i Window Regulator Problems

You have just been promoted at work, and today marks your first day as a boss. To make this day extra special, you put on your best corporate wear while you practice delivering your first executive speech. Nothing else can complete the package other than a compact luxury car that will bring you to your office-a BMW 325i, to be more specific. And so you excitedly drive downtown to meet your new officemates and your brand new swivel chair. During the ride, you decide to roll down the windows to savor the warmth and novelty of the day. Press you did on your BMW 325i window regulator whennothing happens-your car window did not lower even a tenth of an inch. Nasty, isn't it? Don't let such glitches ruin your day. Read more and learn some basic steps you can do to easily troubleshoot BMW 325i window regulator problems.

Stuck windows

Although your BMW 325i window system is primarily composed of gears and an electric motor, the main controller of the whole assembly is still the regulator. So if you're stuck with jammed windows, the first thing that you should do is check your BMW 325i window regulator. You can detach the clips that secure the window assembly to your car's door so that you can have a thorough look at the possible defects of your regulator. A broken regulator requires immediate replacement.

Loose wirings

If you see some loose thin steel wire just about your BMW 325i window regulator, consider replacing the component right away. Loose wirings may result from hard slamming, which shakes the window system assembly inside your door panel. In replacing a loose lifter mechanism (a.k.a. window regulator), do not forget to get improved lock nuts as well. These should hold your BMW 325i window regulator better in place.

Broken electric motor

As most BMW 325i window regulators today are already electric, the problem with your lifter mechanism might involve the tiny electric motor that powers it. To verify if the trouble really originates from the motor, go to the power distribution center. It is just under your car's hood, above the firewall on the left side. Examine fuse number 14 at 20 amp. Any unusual reading indicates need for immediate replacement.

  • Simple Steps to Keep the Good Condition of Your BMW 325i Window Regulator 27 February 2013

    The BMW 325i window regulator is probably one of the car parts you use most often. You press it when you want to lower the windows to let in the cool or warm breeze from the outside. You press it, still, to raise the windows when the outside air already becomes too warm or too cold for you. With such practical function and frequent use, do not expect it to be exempted from wear and damage. If you want to keep your BMW 325i window regulator in its good condition, then you had better read on for some simple maintenance tips.


    Replace defective components.


    Your BMW 325i window regulator works with a web of other window system parts, so if you want to keep a good regulator, it is also important to have well-functioning gears and electric motor. The motor is especially crucial in the function of your regulator, so once you see defect or wear in this part, get a replacement right away. It is also highly suggested to replace as soon as signs of defect arise because BMW 325i window regulator costs are way pricier than they appear.


    Check the parts periodically.


    As the adage goes, it is better to prevent than to cure. So check and work on the minor scratches and stalls right away even before they require major repairs or replacement. To have a good look at each of the components, you may need to remove the door panels of your BMW 325i. This may require some effort, but it still is an easy and sure way to spot possible defects in your car's window system. For all you know, a component might already be decaying in your window assembly, and this might just cause your BMW 325i window regulator to malfunction. One important piece to always keep an eye out for is the gray part on your window system's metal slide. This small piece is essential in carrying the window's weight for the raising and lowering function of your BMW 325i window regulator, and decay on this part can negatively alter the performance of your car's lifter mechanism.
