So you thought you only had two brake lights. Look again and you'll see one in the center at a higher level than the two on either side of the vehicle. They're sometimes in the inside of the vehicle behind the back window, or they could be in the deck lid, on the roof or on the spare wheel carrier, But why is that third brake on your vehicle? Experts say it helps prevent rear end collisions. Tests done by installing the third brake light in taxis and fleet vehicles showed fewer rear end crashes in the ones that had the extra light. The third brake light was mandated in new passenger cars in 1986 in the US and Canada. The requirement was added to new light trucks and vans in 1994. Sometimes it's difficult to know if your third brake light is even working. Many vehicles have bulb warning systems that alert you to non-functional bulbs, but not all do. Your vehicle service facility will often check to see if all your turn signals, taillights and headlights are worki ... read more

You know how heavy your engine and transmission are, so you can imagine how tough the parts that hold them onto your vehicle's sub-frame must be. Not only must they support the weight, they also have to isolate vibrations and noise from the passenger cabin. Pretty tall order, wouldn't you say? The parts that face that task daily are called the motor mounts, or engine mounts. They are usually made of rubber with steel brackets. Others contain a liquid for vibration and sound isolation. Most vehicles have three or four motor mounts, and while rubber or hydraulic liquids do a good job of damping the vibrations from the engine, they also have their limitations. The problem with rubber is that it gets old and brittle. Plus, if there's an oil leak anywhere in your engine and oil gets on the rubber motor mounts, rubber will deteriorate even more quickly. As for the liquid motor mounts, they can develop leaks and stop working. Here are sign ... read more

We've all seen drivers who do things that—let's be frank—really irritate us. They're inconsiderate, can put people in danger and make the road a much less friendly place. They really "T" us off. These are the bad drivers who fit their description to a "T." The Tailgater. You've seen this terrible driver who follows a few inches off the bumper of the vehicle ahead. We all know what's going to happen if the driver ahead of the tailgater has to slam on the brakes. And we've all been that driver followed by the tailgater, whose vehicle fills up your entire rearview mirror. The tailgater is likely not in a great frame of mind and, thanks to his or her stupid driving practices, the "tailgatee" is getting pretty ticked off as well. That's a formula for a big problem. Know anybody who respects or likes a tailgater? Didn't think so The Texter. All sorts of people think they are perfectly capable of texting while driving. I ... read more

The other day, a driver was trying to open his vehicle's hood so he could add some windshield washer fluid. But when he pulled the hood release inside the car, nothing happened. Usually, opening any hood is a 2-step process. You pull the hood release (which is usually a handle under the dashboard to the left of the steering column) and listen for the hood to pop up slightly. (It doesn't open all the way because it has a safety latch to prevent you from accidentally opening it up while you're driving.) Then, you get out and find the latch, usually through the grille near the hood. There's a little handle on it which you push, slide or pull (there are a few different types) at which point the hood can be opened up all the way. But in this driver's case, the hood would not release at all when he pulled the handle inside. Not knowing what to do, he called his service advisor, who told him to bring it over. The reason? A hood with a broken latch cou ... read more

Ever wonder why it costs so much more to fix a similar problem in two different vehicles? Let's say you now own an SUV and before that, you owned a car. Your SUV's air conditioning system needs a new evaporator, but the cost for the new one is way more than you remember it was for your car. How can there be that big of a difference? There are many reasons. For one thing, vehicles aren't all the same. Yes, they have engines and steering wheels and suspensions, but engineering and design can vary widely among different styles and brands. In the case of replacing the evaporator, the one in your former car may have been located in a spot where the technician could get to it easily. Plus, the part may have been less complicated and, therefore, cheaper. Your SUV may require the entire dashboard to be removed with special tools to detach the a/c lines from the evaporator. Plus, since it is supplying cool air to a bigger cabin, it may be more com ... read more

We've all heard that expression, "That's a non starter." When it comes to your vehicle, that's not music to a driver's ears. That sickening sound when you start the ignition and instead of hearing the engine crank, you hear it slowly turn over and your dash lights go dim. There can be many reasons a vehicle won't start, so here's a little history of how the starter came to be an important component of modern vehicles. You have to move the engine's components to start it. The first cars had a crank that the driver would insert into the front, then start turning things over by hand. When the engine started, you had to release that crank immediately or risk a broken arm. Yes, it happened many times. So, they came up with a better idea: an electric starter, which was a big advance in automotive technology. With this system, an electric motor rotated a series of gears that turned the gasoline engine's crankshaft so its pistons and parts moved and the engine drew in a ... read more

When you start up your gasoline engine car, you may not know that it's using the same ignition principles as it has for decades. You have spark plugs that require enough power so a spark can jump across a gap at its tip. Years ago, a vehicle's 12-volt system had to produce 15,000-25,000 volts to do that, so engineers came up with something called an ignition coil that bumps up the voltage. It also has to be done at just the right interval called timing. The first systems had a distributor, a mechanical device with a rotating disc that switched the power to the ignition coil on and off. That higher voltage then was sent to the spark plugs at the correct time interval. But the mechanical "points" had to be replaced and adjusted every 12,000 miles/20,000 kilometers. Engineers later replaced the switching mechanism with solid state ones, but they still needed replacement after 120,000 miles/200,000 kilometers. The next evolution came in the 80's when the distributor ... read more

You may live in a region where roads become pockmarked with craters known better as potholes. They're caused by moisture seeping through a compromised road surface that can freeze, expand and literally punch holes in the road. And when your vehicle hits one of those holes that's big enough, the impact can flatten a tire, bend a wheel or tear apart a suspension component. To minimize pothole damage, leave enough room between you and the vehicle in front of you so you can see the road surface and any upcoming potholes. That way you'll have time to slow down and steer around them. Also, if you see what looks like a puddle of water, it may be hiding a pothole underneath, so treat it as if was a pothole. If you keep your tires inflated to the manufacturer's specifications, they're more likely to withstand hard impacts. And the slower you're going when you hit a pothole, the less likely you are to break something. But if you do find you've hit ... read more

Know anyone who doesn't love a power seat in an SUV, a car, truck or van? They're convenient and precise in their adjustments. But when they break, oh, what a pain. Not only is it inconvenient, it may leave your seat position too close to the steering wheel or too far from the pedals. This is a must-fix problem. There are many things that cause a power seat to fail: Seat controls. These are either at the side of the seat or in the door. Both are places that can be exposed to moisture or other contaminants. When the controls stop working, they usually need to be replaced. Seat motor. Electric motors are what make a power seat move, and sometimes they fail. Sometimes they just get worked to death and die of old age. Replacement is the most common remedy. Fuses. A power seat is, after all, powered by electricity and all vehicle power systems have fuses to protect them. A technician can determine which fuse may have blown and rep ... read more

Vehicle emission testing has become ubiquitous in North America and for a good reason. Clean air quality is important for the environment and all of us. Since vehicle emissions are among the main causes of air pollution, emission testing can alert you to problems in your vehicle than can be fixed so it won't needlessly pollute. Emissions tests are looking for certain toxic gases internal combustion engines produce, such as nitrogen oxide, particulate matter, non-methane organic gases and formaldehyde. Emissions control systems reduce these gases if they are working properly. The best way to minimize pollution is to keep those vehicle systems working properly, and periodic inspection and maintenance is the key. So if you want to make sure your vehicle will pass an emissions test, it helps to know what might go wrong. Let's start on the easy one. Your gas cap could be loose, allowing vapors to escape into the atmosphere. The most common solution ... read more
