At one time or another, most drivers honk their horn at someone who might be texting at a stoplight or not paying attention when they're driving. But what happens when you tap on your horn and all of a sudden it won't quit? Everyone's looking at you like you're an angry jerk and all you want to do is turn it off! It helps to know the basics of what's happening when you honk your horn. There's a switch in the steering wheel, of course, and when you press on it, it sends power to a relay which then energizes the horn. Bingo. Sound. When the horn sticks on, one of these parts or the wiring has developed a problem. With the ear-splitting noise inside your cabin, it may be hard to keep your cool, but do your best to stay calm. Try pushing the horn several times; it may un-stick the switch if you're lucky. If not, there are a couple of things you can try. First, if you can, pull your vehicle off the road and into a spot where you're not disrupt ... read more

If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent. But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust. If there's too much, it means there's a problem with the mixture of fuel and air. The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency. It does this constantly. Many vehicles have multiple oxygen sensors. Some have one close to the engine, another close to the muffler. Two measurements are better than one since they allow readings to be more accurate. You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail. One thing that can damage them is contaminat ... read more

When it comes to your vehicle, driving it too much can cause some issues. But what about not driving a vehicle enough? That has consequences as well. Here are a few things that can happen if a vehicle isn't driven enough. When the engine doesn't operate, the oil isn't lubricating. That means some mechanisms that need periodic lubrication aren't getting it. And oil that sits around breaks down over time. In fact, some experts say you should change oil more often if your vehicle sits in the driveway than if you drive it regularly. You've heard that expression, "Take it on the highway and blow out the engine.” Well, carbon buildup used to be a problem in older vehicles. But the real culprit these days is moisture that builds up from combustion if your vehicle never gets hot enough to burn it off. That water vapor can mix with oil and cause sludge to form. There are many vehicle systems (battery, exhaust system, engine seals, etc.) that benefit fro ... read more

Your vehicle may be wearing boots right now and you might not even know it. They're called ball joint boots. They're actually protective, flexible things that protect parts of your suspension (called ball joints) from all the hazards the road can fling at them. If one of those ball joint boots fails and you don't get it replaced, the ball joints themselves could wind up failing, a repair that can be even more expensive. Ball joint boots not only keep things like rocks, salt, water and dirt out of your ball joints, they also help the ball joints keep their lubrication inside and working properly. To do that, the boots have to be made of a flexible material, sometimes rubber, sometimes a synthetic. They do take a beating, exposed to temperature extremes and debris, and eventually they can tear or crack just because of their age. Unless someone is keeping an eye on your ball joint boots, you may never know there's a problem. That's why when ... read more

We usually take our vehicle's easy steering for granted until something goes wrong. Power steering is what makes it almost effortless to turn the steering wheel, aiming your vehicle in the direction you want to go. Without the assistance of power from the engine, steering would be a laborious process, so you want to make sure the system is working well. Power steering systems are usually one of two types, hydraulic and electric. The hydraulic type uses a pump that is driven by either a belt or an electric motor. This system uses hydraulic fluid to create pressure that gives your steering the power assist. Since that pump is always working, time and distance traveled eventually take their toll, and these systems need to be periodically inspected. Also, while that hydraulic fluid can last for years, it should be replaced periodically as it degrades over time. Your vehicle's owner's manual contains the manufacturer's recommendations. A technician can check fo ... read more
