Take Charge! (Battery Testing)

OK, so you probably take your vehicle's battery for granted.  Turn the key or push a button and it starts right up.  During times of warmer weather, you probably think your battery can take it easy.  But it may surprise you to learn that hot weather can be much harder on a vehicle's battery than cold.  So it's wise to know what condition your battery is in BEFORE you find out the hard way—being stranded by a dead battery.

Your vehicle's battery won't last forever; an average battery will last 3-5 years.  When's the last time yours was replaced? You probably have no idea.  Your vehicle will usually give you some hints that it's in need of attention.  See if any of these are familiar:

• your engine doesn't turn over as quickly as it used to
• your headlights are a little dimmer
• your Check Engine or Battery dashboard light is on
• you hear a click when you try to start your vehicle
• some electrical equipment in your vehicle isn't behaving the way it used to
• your engine smells like rotten eggs
• the terminals on your battery are corroded
• your battery was made more than 4 years ago

Even if there are no signs your battery is on its last legs, it's a good idea to have it periodically checked at your vehicle service facility, at least once a year. A technician will check the date it was made (it's on the battery's case). They'll inspect your battery, cables and connections, looking for corrosion, bulges in the battery or any other abnormal signs.

Using special diagnostic equipment, the technician can run some tests on your battery and vehicle's electrical systems. They can measure how fully charged your battery is and how much potential it has to hold a charge.  Then, your service advisor will tell you how much more life to expect from your battery or recommend it be replaced. 

It you need a new one, your service advisor can recommend options for you. Important factors include brand, warranty, where the terminals are on the battery, the ability to handle different cranking loads and temperature ranges.  Bet you didn't know vehicle batteries can be that different!

Such a Little Part (Climate Control Resistor)

You expect your heater/air conditioner to work like it should.  You have a control for temperature and one for fan speed.  You even have a control for what vents the air comes out of. 

Don't be surprised one day if your blower fan develops a mind of its own and starts going crazy.  Most of the time, you may find that it starts blowing at full speed, and nothing you do to try to control it does any good.  This is what may be happening.

Your blower motor has an electronic component called a resistor.  It does what its name says; it offers resistance.  When you want the fan to run more slowly, you turn the fan speed down.  That resistor accomplishes that by turning its resistance up.  When the resistor fails, the power has nothing to slow it and the fan speeds up. 

It's a small part and can fail due to age or corrosion.  It's usually not an expensive part, either, but it's often found in a location that's not that easy for the technician to get to.  That means labor costs will vary depending on the design of your vehicle. 

Occasionally, a faulty resistor can cause the blower motor not to work at all or only partially come on.  But other things can cause that as well, such as a faulty fan switch or vent control. 

This is where a technician's training comes in.  Special equipment can track down precisely where the issue is so you can be assured the correct part is being replaced.

It's just not pleasant when the blower motor isn't following orders.  Have your service facility check it out so you can be the blower's boss, like it should be.

No Fountain of Youth (Aging Tires)

Can you think of anyone who enjoys aging?  Wrinkles where you don't want them, gray hair, eyes that won't focus any more, no stamina. 

Believe it or not, your tires age, too, and they don't get better the older they get.  And here's the important thing to know, even if they can still pass a tread depth test, they may simply be too old to be safe 

Here's the best way to understand this.  Have you ever found an old deck of playing cards with a rubber band wrapped around them?  Try stretching the rubber band.  SNAP! It's all cracked and brittle.  And you haven't stressed that rubber one bit since the time you put them in that drawer.

Now you know what's happening to your tires.  Rubber ages.  Just like us, the day we come into the world, we start to go downhill (no pun intended).  Oh, engineers are able to make a tire last longer than ever before.  But that gas that keeps us alive—oxygen—seems to love to chemically mix with some components in rubber.  Oxidation causes rubber to become hard and brittle.  The rubber band test.

Is there an age test that can tell you when a tire is tool old to roll? Well, not really.  They don't all age the same.  Hot climates can make tires wear out more quickly.  Some experts say a tire can last up to 10 years but should be inspected every year after the age of five.  Others say tires should have an expiration date at six years old.

Since no one would ever ask a tire its age, how do you know how old one is? Believe it or not, tires made after the year 2000 have a date code stamped on either the inside or the outside of the sidewall.  It's a four-digit numbers; the first two tell you the week, the second two tell you the year. So if it has the number 1916, it was made in the 21^st week of 2016. 

Another way to find out if your tires still have enough life in them is to have your vehicle service facility inspect them.  They look for signs of age, such as developing cracks in the rubber, the condition of the sidewalls and, of course, that old standby: tread.  If it's time to "retire" them, discuss options with your service advisor.

Busted! Air Conditioning (Air Conditioning Maintenance)

Your vehicle's air conditioning is something you count on when the weather heats up.  But there's bound to be a day when you turn it on and one of these things happens:

• Only warm air blows out
• Cold air starts blowing out but then it turns warm on its own
• It's not blowing air at all
• It blows smelly air out

Some people are tempted to try to make the diagnosis—and the repair—on their own.  They think it's just run out of refrigerant and they can pick up a can at a local auto parts store and re-charge it.   If only it was that easy.

A vehicle's air conditioning system is complex and made up of many parts.  A compressor, evaporator, condenser, tubing, hoses, sensors, valves… the list goes on and on.

Each of these components could be the reason for the problem.  It could be a leak that's letting the refrigerant escape, but simply re-charging the system hasn't fixed the problem. You have to find the source of the leak and fix it. Service facilities have a device called a "sniffer" which can sniff out refrigerant chemicals. And they can use black light to locate refrigerant that has an ultraviolet dye in it. 

But often other components wear out; blower motors go bad, resistors blow, tubes clog, compressors fail. And diagnosing that takes training and special equipment you'll find at your service facility.

One other thing to keep in mind.  It's always better to catch any problems in the air conditioning system before it fails. Ask your service advisor about having

the A/C checked as part of the vehicle's maintenance.  That's the cool way to go.
