There's nothing quite like getting in your vehicle on a hot day, switching on the air conditioning and having warm air blow out of the vents. You may have had no problem for months and then, one day, you are driving around in a sauna. You're hot stuff, but not in a good way! So what goes wrong when the AC isn't working? It could be a lot of things because the system has many different components. One thing that's a common cause is the vehicle is low on refrigerant (it used to be called Freon). If that's the case, it's not as simple as simply adding more. Sure, it may fix it quickly for a short time, but it's more likely than not that the refrigerant will just leak out again. The original Freon used in air conditioners was destroying the Earth's ozone layer, so that's not used much any more. But the one that's currently used also contributes to global warming, so it's important that as little of that escapes as possible. So a technician will determine ... read more

You've probably noticed how much easier it is to see when you're driving in the daytime as opposed to at night. It's one of the main reasons about half of all fatal vehicle accidents happen when it's dark. That's why it's important that your vehicle's headlights are in top condition and working the way they should. That means that they're aimed correctly and producing the amount of light they are intended to produce. For many years, headlights were a standardized size and shape. They were what is called a "sealed beam," and when you needed to replace one, it was pretty simple. You just took the old one out and plugged a new one in. But now there are hundreds of different types of lighting systems on vehicles, producing light with such illuminating technology as light-emitting diodes (LEDs), halogen bulbs, high-intensity discharge (HID) bulbs and more. Some vehicles have systems that turn your lights in the direction you turn your steering wheel so you can ... read more

So your vehicle won't start. What's the first thing that comes to mind? Battery dead? Starter motor worn out? Out of gas? Well, those are all reasons that make sense. But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it. Here's how that works. You have lots of computers in your vehicle. They need to know the status of things so there are several sensors monitoring various things going on. These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel. They know when things aren't quite right and prevent you from starting your engine if that's going to damage it. Other sensors make sure the coolant is the right temperature, check to see you are not polluting the air and make sure other electronic components are performing their tasks correctly. Here's an example of a sensor doing its job. Your engine needs oil to lubric ... read more
