It's pretty frustrating when your driver's window won't work. You can't get your food at the drive-thru without opening the door, have a tough time using the ATM from your vehicle, can't have that fresh breeze blowing through your hair as you listen to your favorite road tunes. Plus, there's a safety factor. Your windows provide an escape route in case you need to get out and the doors won't work. Let's take a look at what's going on when your window won't operate. Most vehicles these days have power windows. They have an electric motor in each power window and sometimes those fail. They often give you a warning that they're on their last legs by making a noise or hesitating, so if you get a sign like that, have a technician check it out. Loss of power can also be due to a blown fuse, a bad switch or faulty wiring. All windows have something called a regulator that moves the glass up and down. They have a lot of moving parts in them which can break ... read more

You notice when your smartphone's battery starts to go weak on you. It runs out of juice faster than it did when it was new. Bet you pay attention to that pretty closely. Unfortunately, many of us don't pay the same attention to the battery in our vehicles. If your battery got you through the cold-weather months, you might be thinking you're all set until next winter. But you might be surprised to learn this: Hot weather is harder on a battery than cold weather. (Note: we're talking about a conventional vehicle here, not an all-electric, plug-in one.) The way your vehicle's battery holds a charge is that it has chemicals inside it, and they react with each other to produce electricity. A vehicle battery discharges electricity and then needs to be recharged. Unlike your smartphone that you plug in each night to charge, the way a vehicle's battery gets recharged is by using the mechanical energy of the engine. It's a pretty cool system that's been arou ... read more

Race car drivers have demonstrated the advantages of disc brakes, so most modern vehicles use them. Sometimes just the front wheels have disc brakes, but many vehicles now have them all the way around. A major component of the disc brake is called a caliper. It works by squeezing brake pads against the disc or rotor, kind of like a bicycle hand brake. The brake pads themselves are what contact the rotor, causing friction to build and the wheel to slow down, but it's the calipers that apply the pressure to the pads. Caliper design has evolved over the years, and there are two common types. One is called a floating caliper. It has one or two pistons on one side of the disc. When you push down the brake pedal, the piston or pistons in your caliper put pressure on that one side. A mechanism connected on the other side of the disc applies pressure as well, squeezing your disc so the vehicle stops. Floating calipers are less expensive since the ... read more
