This may have happened to you.  You drive somewhere and get out of your vehicle only to try closing the door and it just won't stay closed!  What a helpless feeling.  You can't lock it; you can't leave it like it is. Or, let's say you head down to your vehicle to head out to work in the morning and you can't open the door.  What are you going to do now? Vehicle doors take a lot of abuse.  They are opened and closed hundreds of times and we expect them to just keep working perfectly all the time.  They do require a bit of tender loving care.  Let's take a look at two different scenarios of stuck doors. First: the door that won't close.  It's a security issue.  It's also a safety issue.  You can't really safely drive a vehicle with a door that won't close. What if you or a passenger is tossed out?  Sure, some people try to tie a stuck-open door closed or bungee it, but that's dangerous.  It's best to get that vehicle to the serv ... read more

Even in the months where temperatures are cooler, heat is still an enemy of your vehicle.  When your engine runs, it creates heat, so there are numerous heat shields that protect other parts from those higher temperatures. Heat shields are installed around several areas of the exhaust system.  Others prevent heat from reaching parts of the vehicle.  Still others prevent heat from reaching the ground (or maybe grass underneath) and starting a fire.  If you remember your space travel history, you'll know how important a heat shield can be. John Glenn was the first American to orbit the earth, but during that maiden orbital flight, a sensor on board was indicating the heat shield on his capsule, Friendship 7, was loose.  If it had come off, his spacecraft could have burned up upon re-entry.  Fortunately, the heat shield stayed on, and Glenn made history. Unfortunately, the heat shields on your vehicle don't have warning systems like the space vehicles did.&nb ... read more

Rust.  It's worse if you drive in places that use salt on the roads in winter, or if you spend time driving near a body of salt water.  But any vehicle has to deal with rust after years on the road.  And it's not just that rust can eat away your vehicle's body and fenders.  It can be a real problem around your suspension, drivetrain or any place where there's metal. Rust takes its time.  You don't see it until it's already done its dirty work.  It can wreak havoc with your electrical system.  Sure, vehicle manufacturers do their best to keep it to a minimum, but especially with road treatments like brine around, their task is a difficult one. The one spot everyone notices is in the paint.  You see a little bubbling under the once-smooth surface.  By the time it bubbles, it's well involved in rotting away that spot of your vehicle.  You wouldn't believe how just a little thing can start the process on its way.  A stone chips the pai ... 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

Most light vehicles (under 10,000 pounds/4,500 kg) in North America sold from 2008 model year on have a feature that many people are confused about.  It's the tire pressure monitoring system (TPMS).  You may have some experience with it yourself if you own a newer vehicle.  Vehicles with TPMS have sensors in each tire that are supposed to warn the driver when tire pressure gets dangerously low.  That's important because tires that are significantly under-inflated can cause very serious accidents. Unfortunately, many drivers think the TPMS does all the work keeping track of tire pressure. To them, as long as the warning light or gauge isn’t giving a warning, the tires must have the proper amount of air pressure in them.  That's not the case. Tire pressure monitoring systems aren't all created equal.   Some give you a digital readout of the pressures in each individual tire.  But many simply have a warning light that looks like the cross sect ... read more

If you've ever noticed your vehicle's lights are dim or not working at all, the problem could be many things.  But one possibility is your battery cables aren't doing their job.  A power outage in your vehicle is similar to one in your house and needs to be repaired to get things back to normal. Battery cables connect your vehicle's battery to the vehicle itself.  There is a positive cable when provides the power and a negative cable that connects to the vehicle chassis and provides a ground for electrical components.  A failing battery cable may cause your vehicle not to start.  Your starter may turn over very slowly.  Or you may just hear a series of clicks.  One other clue is on your dash—the battery warning light.  There are many things that can cause power issues in a vehicle, but it's important to keep battery cables clean and maintained.  Salt and corrosion are enemies to any power system.  A technician can keep things in t ... read more

Heat isn't easy on vehicle tires, and as the seasons change, make sure yours are ready to take the heat.  Let's talk first about inflation.  Heat causes air to expand, so heat alone can raise the pressure in your tires.  If you are driving on overinflated tires, they won't have as much contact with the road surface.  In that case, it will take you a longer distance to stop. On the other hand, you don't want your tires to be underinflated during hot weather, either.  That can cause your sidewalls to flex.  Friction will then hike up the temperature and your tire can be in danger of blowing from the added heat. Other things can cause problems, such as uneven wearing.  Your service advisor knows the signs to look for and can diagnose where the wear is and what is likely causing it.  Another thing a technician will look for on tires is tread depth and the condition of the sidewalls.  Any cuts, cracks or bulges could be indications that your tire ... read more

There's nothing like that sinking feeling when you turn the key and nothing happens in your vehicle.  A lot of us are quick to blame the battery.  But it may instead be your alternator that's failing. Your battery supplies power to start your vehicle, but the alternator is what sends power when your engine is running.  The good news is alternators last a fairly long time, and it's not unusual to get seven years out of one. But they can give up the ghost thanks to the harsh conditions in the engine compartment. Alternators have bearings inside them that keep things turning smoothly.  Debris, liquid, dirt and more can team up with the high temperatures your engine generates to cause those bearings to seize up.  That's not good, and if that happens, you may even be able to hear the bearings grind. Other symptoms of a dying alternator are a squealing noise in the engine compartment or your headlights may go dim and bright, dim and bright.  You might even notic ... read more

The heat is on, and your vehicle takes a beating when it is.  Several of your vehicle's systems are under extra stress in hot weather, so here are a few to make sure are getting the care and maintenance they need. It makes sense that the cooling system is one to make sure is in top shape.  Vehicle breakdowns in summer are often due to a problem with one of the cooling system's components.  Coolant levels have to be up to specs, the ratio of coolant to water must be correct and the hoses, pumps, belts and radiator must all be working properly in order to prevent vehicle overheating. Summer is also hard on your air conditioning system.  You might find that no air is blowing out of the vents or maybe only hot air is coming out.  Air conditioning equipment is best diagnosed and repaired by a trained and experienced technician.  The problem could be in any number of components, including the condenser, compressor or blower motor. You may think the battery gets ... read more

Quick question.  Which is tougher on a vehicle's battery, the heat or the cold? Believe it or not, it's the heat.  Think about it.  The battery often sits in the engine compartment next to that motor generating lots of heat.  That can accelerate corrosion in the battery and may even cause water in it to evaporate.  That will weaken the cranking power of your battery and shorten its life span. To take care of your battery, here are a few suggestions.  It's a good idea to have it checked out to see what shape it's in.  At your vehicle service facility, they have diagnostic equipment that can evaluate its condition.  That can help you know how long you can expect it to last before having to replace it.  At the same time, you should have your charging system evaluated.  If your battery is not getting charged properly, it can be in great shape but not very useful when it comes to starting your vehicle.  A technician will also check the ... read more
