Why You Need a BMW Electrical Mechanic? While BMWs are renowned for their high quality and performance, proper operation necessitates a large number of electronic systems. Often, these systems will fail or develop problems over time and need a professional BMW electrical mechanic to fix them.
The majority of electrical problems can be quickly and easily fixed, which is good news. These problems typically occur due to a faulty battery, failing alternator, or wiring.
Have a BMW electrical mechanic check for faulty wiring
The wiring harness in a BMW is a complex system made up of electrical connections and hardware components. When this wiring harness is damaged, it can lead to serious problems.
In many cases, faulty wiring can be repaired without needing to replace the entire harness. However, it’s important to have a qualified BMW electrical mechanic perform routine inspections to avoid problems down the road.
The fuse box, which is typically located in the trunk of older versions or the box of newer models, may have blown a wire if your vehicle’s interior lights or stereo aren’t functioning properly. Another common cause of problems with the entire electrical system is a blown fuse, which may indicate that your alternator isn’t functioning properly.
Have a BMW electrical mechanic check a dead battery
Every car has a rechargeable battery that stores electricity, which allows your electric system to work properly. The battery starts the engine and provides power for headlights, cabin lights, and other electrical components.
Keeping the battery charged is easy. Your car uses an alternator that charges the battery while you drive. However, the battery can become corroded and fail to charge. This can cause a variety of electrical problems, including dimming headlights and dashboard backlights.
If the battery has been left unattended, it may drain quickly and leave you unable to start your BMW. Loose connections or frayed wires can also drain your battery, so it’s important to have your BMW’s electrical system inspected by an experienced BMW electrical mechanic.
Have the BMW electrical mechanic check the failing ignition switch
One of the most crucial electrical parts in your vehicle is the ignition switch. It’s attached to the steering column behind your ignition lock cylinder and powers up virtually every electronic device in your vehicle.
You’ll want to replace your ignition switch as soon as possible if it starts acting up. This will prevent you from being stranded on the side of the road. A failing ignition switch can cause a number of symptoms, including a faulty engine or trouble starting your car.
Another symptom of an ignition switch problem is that your dashboard lights flicker sporadically or won’t work at all. This is usually a sign that your transition isn’t working properly or that the cable in your car is. Your ignition switch can be examined by an ASE-certified BMW electrical mechanic engineer to see if it needs to be replaced. Contact Wrench’s mobile mechanics today to schedule an appointment.
Failing Turn Signals
When you drive a BMW, you need your turn signals to be working. They are a crucial safety feature and should always be used. If one or both of your turn signals are not working, they may have a problem with the bulb or flasher unit. Check your owner’s manual to find the proper bulbs and sockets for your vehicle model.
You may also want to look for a bad ground connection at the bulb socket. This can be caused by dirt or debris on the bulb socket, or corrosion. Another issue could be a blown fuse or a bad flasher unit. You can troubleshoot these issues using a test light. If you cannot fix the problem despite your best efforts, try contacting a BMW electrical mechanic.
Slow-Moving Windows
Power windows are a modern convenience that makes it possible to open and close your vehicle with ease. But they can also be a pain when they stop working.
If your electric window motor isn’t moving your windows, it’s a good idea to check for loose connections or faulty wiring. First, trace the wiring path from the switch to the window motor. Use a multi-meter to confirm that the motor is getting the proper voltage. Then, toggle the switch up and down and watch for any slow spots or blockages in the circuit.
This is a good indication that the window motor needs to be replaced. In most cases, a qualified BMW electrical mechanic will be able to replace the window motor for you. Keep in mind, however, that replacing the motor involves special tools and expertise.
