No matter what vehicle you drive, when certain things break, you have to make a decision.  Should I get it fixed now, later or never?  Air conditioning is one of those things.  You can certainly live without air conditioning, but it sure is nice to have on a sweltering day. Let's say your air conditioning breaks in the fall and you live in a climate where it gets quite cold in the winter.  Should you get it fixed now, wait until spring since it won't get warm until then or maybe not get it fixed at all? That can be a tough decision.  There are several reasons air conditioning in vehicles break.  One is fairly simple: It could be an electrical problem, perhaps a relay or solenoid is not turning on the system.  It's also a fairly inexpensive repair and doesn't require hours of labor. Or, the problem is that the coolant has leaked out.  Your service facility can find the leak and replace the parts that are leaking.  With a refrigerant recharge ... read more

Can you think of anyone who likes getting a flat tire?  Of course not.  But when one of your tires winds up with a flat or leak, whether it be from things like hitting a curb, running over a nail or picking up a sharp stone, it's time to have someone who knows what they're doing take care of it. If you're thinking you'd like to avoid having to buy a new tire, you wonder if a patch or plug will suffice.  It depends where the puncture is and how big the hole is.  Most tire experts will say if the hole in the tire is less than ¼ of an inch or 6 mm, a patch can work.  But a patch likely won't work if the compromised part of the tire is on its shoulder or sidewall. Here's why.  The shoulder of a tire is the part between the sidewall and tread and it's usually rounded.  It's under a lot of pressure, more than even the sidewalls. And because of that curved shape, it's hard to get a patch or plug to hold. The sidewall is the side of the tire.  Sid ... read more

Air conditioning used to be a real luxury in a vehicle, but now it's standard in most.  Your vehicle's air conditioning system is built to last a pretty long time, but like anything mechanical, sometimes it fails.  It helps to know a little about how the A/C works. There's a compressor that pressurizes the refrigerant (you probably recognize the term Freon).  That makes it hotter, so it then goes through a condenser that cools it off.  Then another component takes out impurities and humidity before the Freon goes to a device that makes it lose pressure before it goes to the evaporator.  That's where it gets colder and takes the humidity out of the air. Then your vehicle's ventilation system blows air over the evaporator, cooling the cabin air that gives you such relief on a hot day. Of all these parts, one that does a lot of work is the compressor.  It has to compress that refrigerant and circulate it through the system.  It turns on and off several t ... read more

There are some dashboard lights you should pay more attention to than others.  One is the air bag light.  If it's on and your vehicle is in an accident, your air bags probably won't do their job. Automakers began installing air bags in the late 1990's since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt in combination with an air bag gives passengers the best chance of surviving a crash and minimizing serious injury. The air bag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated air bag from a side view.  Or there may be a warning light that says something like "Air Bag," "SRS" (for supplemental restraint system), "Airbag Deactivated" or "Air Bag Off." Different things cause the air bag light to come on.  Your vehicle may have been in an accident during which, while the air bags didn't inflate, crash s ... read more

In a perfect world, all wheels and tires would be perfectly round and weigh exactly the same at every point of the wheel.  Unfortunately, they're not, and if they're out of balance, they can reduce the lifespan of your tires, make your vehicle shake like a carnival ride, and maybe even damage a few suspension parts along the way.  You don't want that! Wheel balancing, sometimes known as tire balancing, is a process by which a technician makes sure your tire/wheel assembly has evenly distributed weight.  If it isn't, it can give your ride bad vibrations.  If you feel your vehicle's steering wheel shaking, it can mean unbalanced wheels in the front. If you can feel a vibration in your seats, it could be unbalanced rear wheels. In addition to your vehicle vibrating at higher speeds, there are other signs that your wheels are out of balance. You may see uneven tread wear, or you may notice you aren't getting the kind of fuel economy you used to.  When you experienc ... read more

There's a belt that snakes through your engine.  It's even named for a snake, the serpentine belt.  It'll bite you when it breaks, possibly leaving you stranded.  So, it's good to know a little about this snake-like belt. In early engines, there were lots of belts. They were used to convert the rotating power of the engine to turn a mechanical part.  But engineers had an idea.  Why not consolidate all those belts into one that ran a bunch of different parts simultaneously? Voila!  The serpentine belt. It's found in the front or side of your engine unlike older belts which were often in a V shape, the serpentine belt has ribs on it which more effectively connect with the pulleys that power the other components.  A serpentine belt may power the water pump, power steering pump, alternator, and the air conditioning: all from one crankshaft.  Now, all that's fine when everything is working well and the belt is intact.  But when a serpentine belt ... read more

You are heading down a flat, newly paved street when all of a sudden you feel it.  Your vehicle jumps a little bit when you're accelerating and changing gears.  You know it's not the surface of the road because it's smooth as silk.  So what did you just feel? That kind of jumping—or grinding or slipping—during gear changes could be a sign of trouble in your automatic transmission.  And it's important to get it checked out fairly soon because some transmission problems that aren't fixed early can lead to more involved and expensive repairs. By far most vehicles on the road in North America have automatic transmissions, and they are workhorses.  Unlike early cars with balky, hard-to-shift manual transmissions, the latest automatics allow you to drive without having to even think about gear changes.  But you should know about a few signs of trouble to look for if they ever start showing up. When you first get going and shift your vehicle from Par ... read more

You may remember a song that went, "Objects in the rearview mirror may appear closer than they are." While that was a song about life's lessons, there are a few things we should all know about how important rearview mirrors are to safe driving. While new electronic devices are helping drivers be aware of surrounding traffic in high-tech ways, the good old rearview mirror is still a dependable way of letting you know what's around you.  There are usually 3 on each vehicle, 1 attached to the windshield inside and 2 attached outside on each of the front doors. It's important that they be adjusted properly before you start driving (not while you're driving). Experts say the windshield rearview mirror should cover the area behind the vehicle while the outside mirrors should not simply duplicate that view but extend it to the sides, where blind spots normally are. Your rearview mirrors must be able to hold the positions they're adjusted in; it there's play in them or they move around, y ... read more

Recently, Nissan introduced the latest version of its Leaf, the company's electric car. It has many new features, including something called e-Pedal. It allows the driver to let up on the accelerator and, unlike a gasoline engine car, the Leaf doesn't just slowly lose speed; letting off the throttle pedal brakes the car in a very controlled way, using regenerative and sometimes friction brakes. With practice, a driver can go for a fairly long time without touching the brake pedal. Another system, similar to those found in self-driving vehicles, can steer the car to keep it in the center of the lane using a camera and radar. It literally watches the lane markers and, of course, doesn't work well in snow that obliterates those markers. But the technology is impressive and can greatly reduce fatigue on long trips. In fact, much of this technology has "trickled down" from research on autonomous vehicles, such as adaptive cruise control that slows down your vehicle (even to a stop) if the v ... read more
