4 Essential Things to Know About Your Car’s Power Windows

Power windows are windows in a vehicle that can be opened and shut with the push of a button. Vehicles without power windows have a crank handle. Power windows are convenient as they let you focus on the road while opening or closing the window.

Benefits of Power Windows

Power windows are standard on most vehicles today. They allow people to control the vehicle better and allow easier access for those with arthritis, or hand injuries, to roll down the windows without as much pain. In addition, the windows in the back can be controlled from the front using the master panel. This is very helpful when children are in the back seat, and are unable to reach or roll the windows down themselves.

How Power Windows Work

Power windows have an electronic motor attached to a worm gear, which is attached to several other gears, to create torque to lift the window. A long arm is attached to a bar at the bottom of the window. One end of the arm slides into a groove as the window rises up. On the opposite end of the arm is a gear with teeth cut into it. The motor turns this gear to engage these teeth allowing the window to open.

Power Windows That Don't Work

Power windows can stop working without warning. The most common cause of this is because their regulators and motors are used more often than other features of the vehicle. If your power windows have stop working, have them checked out by a mechanic as this is a safety issue. Passengers may need to exit through the windows in case of an emergency.

Other Common Problems with Power Windows

One of the reason power windows fail is because of a faulty window regulator, which is also called a window track. They also fail because of a broken motor, bad window switch, or a broken cable pulley. The main causes to these malfunctioning include snow and ice. As the area around the glass freezes, the window regulators have to work extra hard, making the mechanism wear out prematurely.

Power windows are convenient and easy to use. Furthermore, they come standard on most vehicles. If your power windows stop working all of a sudden, consult the professionals at YourMechanic to have windows inspected right away. In addition, let the car warm up in the winter allowing the snow and ice to clear from the window. By doing this the regulator won’t have to work as hard.

Volkswagen Will Only Sell Its ID Electric Cars Online

Volkswagen Will Only Sell Its ID Electric Cars Online Volkswagen  is switching up the way it sells its electric vehicles. The company’s dealerships will no longer be the primary point of sale for the ID family of EVs. Instead, they will assume the role of an “agent” that facilitates the sale. If you’re in the market for a  VW EV , you can now place an order directly with Volkswagen and choose your preferred dealer. Instead of giving you the hard sell when you walk into the dealership, the dealer will now be focused on organizing test drives, facilitating the transaction and making sure you get the keys to your new wheels without a hitch. The price of the vehicle, plus the dealership’s commission, is fixed, which will bring some financial relief to dealers, too.

Windshield wipers on connected vehicles produce high-accuracy rainfall maps

Image
Connected vehicles are poised to transform the field of environmental sensing by enabling acquisition of scientific data at unprecedented scales. Drawing on a real-world dataset collected from almost 70 connected vehicles, this study generates improved rainfall estimates by combining weather radar with windshield wiper observations. Existing methods for measuring precipitation are subject to spatial and temporal uncertainties that compromise high-precision applications like flash flood forecasting. Windshield wiper measurements from connected vehicles correct these uncertainties by providing precise information about the timing and location of rainfall. Using co-located vehicle dashboard camera footage, we find that wiper measurements are a stronger predictor of binary rainfall state than traditional stationary gages or radar-based measurements. We introduce a Bayesian filtering framework that generates improved rainfall estimates by updating radar rainfall fields with windshield wiper
