It's no fun when your vehicle just doesn't run the way it used to. You may notice (especially in cold weather) the engine won't start easily or when it does start, it doesn't run smoothly. It may not have much power at all. You also may have had to stop at the gas station more often, a sign your fuel economy isn't what it used to be. There could be a few different things that cause those symptoms, but one culprit could be a bad ignition coil. The coil takes the voltage from your battery and multiplies it before that power is sent over to a spark plug. That allows the plug to fire off a good jolt of electricity that ignites the fuel in your cylinder and powers the engine. There's usually one ignition coil for each cylinder (or sometimes for a pair of cylinders). If only one of them is not pushing out enough electricity, it can cause big trouble with your engine performance. Other signs of a bad ignition coil include engine backfire, an oil leak and your Che ... read more

It's chilly outside. You flip on that switch that looks like a picture of a seat with little heat waves rising from it. You expect soon you'll feel that warmth but… wait! It's not getting warmer. Oh no, what's wrong with my seat heater? There could be lots of reasons it's not working, and it could be as simple as a fuse or as major as the heating element itself. But it's something to leave to a pro to diagnose and repair. Let's say it turns out to be a blown fuse. Simply replacing the fuse may not fix it because there was a reason the fuse blew in the first place. It's possible the on-off switch has worn out or corroded. Perhaps the wiring connection isn't completing the circuit (could be corroded or full of dirt) or the voltage reaching the heating element isn't correct. There's a little sensor that keeps track of the seat heater's temperature called the thermistor. When the seat is hot enough, it will stop the juice from heating ... read more

Alfred Hitchcock once made a mystery thriller film called "Rear Window." It had nothing to do with the rear window of today's cars, SUVs, CUVs and light trucks. But there is one thing that some drivers DO find mysterious. Why don't the rear windows in the second row of many of these vehicles go down all the way? You've probably seen or owned one or two. That rear side window only goes down about a third, a half or three-quarters of the way. Yet there are some similar vehicles where the window goes down all the way. What gives? There was the rumor going around that the restriction on how far those windows could go down was a child safety feature. The thought was that if those windows couldn't open up fully, a child (or pet) would be less likely to fall out. But it turns out the real reason is that the way the rear doors were designed, there was just no room for the window to go down all the way into. Many vehicles are configured so that the rear wheel arch ... read more

In a year marked by unusually heavy flooding in North America, drivers are very aware of the possibility they may find themselves driving where water has come over the road. It can be a daunting and frightening situation. Flooding waters can move quickly and unpredictably, so you have to keep your wits about you when you encounter that situation. Here a sample of one vehicle manufacturer's guidelines on what to do. First, the vehicle is designed to go through some water, but you must be careful. Never attempt to drive through water deeper than the bottom of your tires. You can get out of your vehicle to check the depth of the water, but you can never be sure that you aren't going to drive into a spot where the road has washed away. You can't see below the surface of the water, and suddenly you could find yourself in a place where the road drops off unexpectedly. In swift moving storm runoff, your vehicle could literally be floating away with the curr ... read more

Today's vehicles have some pretty amazing technology in them, including a computerized braking system we all pretty much take for granted these days. Antilock brake systems (ABS) have been around for years but they help drivers stop in much shorter distances reliably than ever before. When you see your ABS warning light come on, it's important to find out what's causing the problem. It's a safety issue. Often the problem when the ABS light comes on is a faulty wheel speed sensor. (In some cases the traction control light will also come on, perhaps because of a non-working wheel speed sensor.) Your vehicle uses the speed sensors to measure the rotational speed at each wheel. That sensor sends the speed data to a computer that can then adjust braking power and prevent your wheels from locking up. If any of the wheel speed sensors isn't working right, the ABS warning light will go on and the vehicle's computer will turn off the antilock brake system. You'll s ... read more

Things we don't expect happen to our vehicles. And let's face, no one really wants to spend money on an unexpected repair. But if you are putting off going to your vehicle repair facility because you're dreading bad news, you might just be putting off some good news. There was one minivan driver who'd had the same van for years and never had a problem with the power sliding doors. Then one day, the electrical switches in the door pillars stopped working. The key fob would still open them, but the door switches wouldn't do a thing. Of course, the van driver feared the worst: an electrical problem, a major computer failure, mice chewing up the wires. So, he put off going into the repair facility for a couple of months. One day, it was time for his regular oil change and the service advisor asked him if there was anything else going on with the van. The owner mentioned the door problem but said he didn't want to spend a fortune on it. He waited for his van, a ... read more

In the hot weather, seeing steam coming from the engine compartment is something we all dread. No one wants that to happen to them. But if you know the signs of overheating and how to deal with it, you may be able to reduce the risk of damage to your vehicle, maybe even prevent getting stranded on the road. Besides the steam coming out of the engine compartment, here are a few signs of overheating. Your vehicle has a heat gauge that may have a needle that can go into a red zone or up to the "H" (for High) position. You may smell odors, perhaps a burning (could be hot oil) or a sweet smell (engine coolant leaking). When you encounter any of those signs, you know you have to do something to keep the engine as cool as possible to avoid potentially catastrophic damage. Turn off the air conditioning and turn up the heat. While that last part may sound odd, it helps draw heat out of the engine. If you can do it safely, pull off the road to a spot awa ... read more

The pungent smell of rotten eggs can send people running for the hills. So when that odor is inside your vehicle, yikes! Yolks! The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another words that begins with S. Sulfur. Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned. You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should. That could be due to age, damage or an abundance of oil that's clogging it up. If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture. That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe. There's another possi ... read more

If you park your vehicle outside, you are exposing it to all sorts of critters that would love to use it for nesting, food storage and shelter. There are plenty of pictures online of people who've discovered there was more than an engine under the hood. In one case, the driver of an SUV started to smell a slight burning odor when she was driving. Turned out to be 200 walnuts and a lot of grass had been stored there by some industrious squirrels preparing for the upcoming cold weather. The SUV owners had their vehicle inspected not long before this happened, but it doesn't take some animals long to set up house in what they think is the ideal spot to make their winter home. Obviously, that can create problems. Squirrels, mice, rats and other small animals can chew through hoses and wires. Plus what they store as food and nesting material may prevent engine parts from moving the way they are supposed to. Imagine a radiator fan that wo ... read more

Synthetic motor oil has been around for a long time, and more and more new vehicles are leaving factories with synthetic in their engines. But a lot of drivers don't really know much about it.Let's start with conventional oil – the kind folks are used to. Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths. Like a pile of pencils, some of them new and some of them used.Synthetic oil is man-made. Its molecules are more uniform and regular in shape – more similar to marbles than pencils. Some synthetic oil starts with a petroleum base that's modified and others are entirely synthesized from other materials.Synthetic motor oil works better in both hot and cold temperatures. It's more chemically stable so it doesn't readily evaporate or break down in the high heat produced inside your vehicle engine. This means it resists turning to sludge, which is a real engine killer.Remember that marbles and ... read more
