A Non-Starter (Alternator Problems in Cold Weather)

Posted February 23, 2020 10:22 AM

As the temperatures dip, we all know there could be problems starting our vehicles. After all, batteries can grow old and not hold a charge as well as when they were newer. Or starters can go bad.  But there's one more component to keep an especially sharp eye on during winter: your alternator.

The alternator is sort of like a small generator. It sends power out to various parts in your vehicle that need electricity.  That includes the battery, which needs charging to keep its power topped off.  The alternator creates electricity by taking mechanical energy from the engine and turning it into electricity.  It is connected to the engine by belts and pulleys. 

In cold weather, the material the belt is made from is less flexible than it is in warm weather.  That means it may not be turning the pulleys as effectively since it doesn't have the same grip. Also, when it's colder, lubricants, including the engine oil, are a little stiffer and parts just don't move like they do when the weather's warmer.  With that extra strain, sometimes it takes the alternator longer to recharge the battery. That, in turn, may leave the battery a little less power to start the engine when it's cold.

You may have a warning light on your instrument panel that looks like a battery.  If it lights up or if you notice your headlights flickering or not shining quite as brightly as they usually do, it could mean a weak alternator. But it also could be an aging battery, corroded battery terminals, a loose belt or another charging system part. Yes, it's complicated. 

Pinpointing the cause involves testing the battery and charging system with diagnostic equipment.  If it does turn out to be an alternator, there are options besides replacing it with a brand new, original equipment part.  Ask your service advisor for recommendations. Obviously, you want your vehicle to start reliably, especially in cold weather.  Take care of your charging system and it will take care of you.

Thoughtful Gifts for the Winter Driver

Posted February 16, 2020 11:21 AM

You may be one of those romantics who don't like giving (or getting) practical gifts for special occasions.  Just wait until one of those gifts helps you out of a big predicament in cold weather, and you realize that practical gifts can be life savers.

Here are a few things you may give the cold-weather driver in your life—or suggest to someone else to give you!

  • A portable air compressor.  If you've ever had a flat and you can't imagine trying to change a tire on a snowy, winter day, this may just get your tire pumped up enough to drive over to the repair facility.  Some are fancy and pricey, some are only a few bucks.  They plug into the cigarette lighter/12v outlet and will take a few minutes to pump up your tire. But it could save you a tow.
  • Portable jump starter. These are relatively small power units (they easily fit in a car trunk) that can jump start your vehicle that has a dead battery.  Some even have an air compressor built in.  If you've ever tried to use conventional jumper cables in freezing weather, they can be stiff and hard to manage.  Really handy when there are no other people or vehicles around and you need a jump.
  • Flares.  When bad winter weather reduces visibility to dangerously short distances, flares can make the difference between someone seeing you broken down at the side of the road and them ramming into you. Flares put out far more light than nearly every other warning device; just ask law enforcement officers who carry flares in their patrol vehicles. 
  • A good tire gauge.  Winter is when temperatures plunge.  When the temperature drops, so does your tire pressure, so it's important to check your air pressure properly and accurately so you don't wind up with one or more deflated (and flat) tires.  The proper time to check pressure is in the morning, before you hit the road and your tires heat up.  Properly inflated tires are important for safe traction, especially during winter.
  • Kitty litter.  The lowest-tech gift of all.  Keep a bag in your vehicle and it can provide much needed traction if you get stuck in the snow.

Visibility Disaster! (Windshield Washer Pump Replacement)

Posted February 9, 2020 8:28 AM

Let's say you live in a cold climate where the snowy, icy weather challenges you to clear the salt and debris tossed up on your windshield.  You push your windshield washer switch expecting a good stream of fluid so the blades can wipe the glass clean. Yet nothing comes out.  Nada, zip.  What's going on? You know you filled up the windshield washer reservoir within the last week or so. 

Well, there could be a few things causing your windshield washing system to fail.  One culprit? The hoses that are supposed to carry that fluid from the washer pump to the spray nozzles may be frozen, or maybe they're cracked and leaking. It could be the nozzles themselves are stopped up, either iced up or jammed full of debris.  Your windshield wiper/washer switch could be worn out or the electrical system may not be conducting power to the washer pump. 

It's important that this system work properly, especially on days when the sun may be in front of you and your windshield is covered with a cloudy, icy mess.  Seeing what's going on in front of you may be like trying to peer through frosted glass, and that's not a safe situation for you or the drivers around you. You need to have this checked out by a technician as soon as you can.

Let's say the technician discovers it's not any of those components.  Turns out it's the electric windshield washer pump itself that's failed. After replacing it, everything is working fine, and you can see again.  As so often is the case with today's complex vehicles, figuring out the root cause of a problem can be tricky.  Rely on your vehicle service facility since they have the know how and diagnostic equipment to make sure your view of the road will always be crystal clear.

In the Hot Seat (Repair and Maintenance of Seat Heaters)

Posted February 2, 2020 8:28 AM

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 it any more.  Sometimes those fail.  But if all of these components are healthy, you may need a new heater element. 

Those seat-heating elements are made up of wires that get sat on.  A lot.  That can put significant strain on them.  Putting something heavy on the seat can break them. Or, if you put your knees on the seat cushion as you're getting something in a rear seat, that can also damage the element.  Sometimes they can be repaired but often they have to be replaced.  And here is where the technician's expertise comes into play.  That heater element is attached to the seat's fabric and replacing it can be tricky.  It also can require disassembling a lot of the seat to access it. 

Seat heaters are a wonderful feature and they make your vehicle oh, so much cozier.  So keep them working and enjoy the warmth!
