Your Vehicle's Hissy Fit (AC System)

When you hear hissing sounds coming from your vehicle, you might start thinking the worst.   One type of hissing coming from around your air conditioner may be a normal sound, or it could be a sign of serious trouble. First - the normal sound.  When you turn off your vehicle, the refrigerant goes from its high-pressure side to the low-pressure side. Some of those noises are normal.  But when it hisses all the time, that's another story. One cause could be that the refrigerant is leaking.  Air conditioners are fairly complex systems that involve various pumps, hoses, valves and motors.  When your air conditioner is cooling, the refrigerant changes from a gas to a liquid and back.  That refrigerant is under pressure, and there are many places it can leak from.  A hissing sound can also be a failed valve in your air conditioner's compressor.  It is what controls the refrigerant's pressurization.  It's important to have this fixed fairly qu ... read more

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 faci ... read more

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 ... read more

Air Conditioning Maintenance at Walker Automotive in Wilmot

Warm weather or cold, Wilmot drivers still need to think about their vehicle's air conditioning. Most Wilmot people don't service their air conditioning until after it fails. At Walker Automotive, we can advise you on your vehicle manufacturers preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on. Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the vehicle's air conditioning system allow the refrigerant to escape and the system can't cool the air as well. We see that a lot at Walker Automotive in Wilmot.The refrigerant also contains oil that lubricates air conditioning components and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all Wilmot vehicle owners know that air conditioning repairs can be costly.&n ... read more

Differential Service at Walker Automotive

Here at AutoNetTV, we have national viewers, like your neighbors in Wilmot, who write to us with questions or feedback. One common question we're asked is: "What is a differential and what does it do?" You may have been told by your Walker Automotive service advisor that your differential needs serviced, or it's seen it as an option up on the service menu. Differential service at Walker Automotive covers a lot of things, so let's first talk about what a differential does.As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track - the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don't hop or skip while taking corners, or lose traction in dirt or snow on Wilmot area r ... read more

Winter Watch List (Winter Maintenance Items)

Don't love winter weather? Here's a list of four things you need to keep a watch on during the winter months. Let's start with coolant levels.  Coolant is as important in cold weather as it is in hot weather.  Think of the term "anti-freeze." Your coolant needs to be adjusted for climate and temperature so the coolant doesn't freeze when the vehicle isn't running. Your service facility will know the right mixture. Next, windshield wiper fluid. Winter weather can be challenging when it comes to visibility, so it's important to have the correct windshield washer fluid.  Some of it is specially formulated for ice and freezing temperatures. And it won't freeze if your vehicle has to sit out in below-freezing temperatures.  And don't forget you can get winter wiper blades that stay clearer in snowy, icy weather than ordinary blades. Don't forget your tire pressure and tread.  After all, tires are what connect your vehicle and the road.  As temperatures go down ... read more

Prepare Your Windshield for Winter (Wiper Blades and Fluid for Freezing Temperatures)

Winter and freezing temperatures present challenges for different parts of your vehicles.  For example, winter tires give you better traction on snow.  But some parts of your vehicle that may need special attention for winter are your windshield wipers. You may have found yourself in the middle of a snowstorm when your windshield wipers are doing nothing but streaking slush that ices up on contact on the glass.  Now you're more blind than you were before! Obviously being able to see during a snowy or icy winter event is important for the safe operation of any vehicle.  So keeping your windshield and rear window clean can go a long way to guarantee you can see your surroundings. Let's start with the wipers.  Blades that are good for hot weather may not be robust enough for freezing weather. You can buy special winter wiper blades that stay flexible during sub-zero temperatures.  The stiffer frames that hold them have a rubber covering that prevents ice and ... read more

Not So Cool (Air Conditioning Systems)

There's nothing quite like getting in your vehicle on a hot day, switching on the air conditioning and having warm air blow out of the vents.  You may have had no problem for months and then, one day, you are driving around in a sauna. You're hot stuff, but not in a good way! So what goes wrong when the AC isn't working? It could be a lot of things because the system has many different components.  One thing that's a common cause is the vehicle is low on refrigerant (it used to be called Freon).  If that's the case, it's not as simple as simply adding more.  Sure, it may fix it quickly for a short time, but it's more likely than not that the refrigerant will just leak out again. The original Freon used in air conditioners was destroying the Earth's ozone layer, so that's not used much any more.  But the one that's currently used also contributes to global warming, so it's important that as little of that escapes as possible.  So a technician will determine ... read more

Give it the Boot (Ball Joint Boot Replacement)

Your vehicle may be wearing boots right now and you might not even know it.  They're called ball joint boots.  They're actually protective, flexible things that protect parts of your suspension (called ball joints) from all the hazards the road can fling at them.  If one of those ball joint boots fails and you don't get it replaced, the ball joints themselves could wind up failing, a repair that can be even more expensive.  Ball joint boots not only keep things like rocks, salt, water and dirt out of your ball joints, they also help the ball joints keep their lubrication inside and working properly.  To do that, the boots have to be made of a flexible material, sometimes rubber, sometimes a synthetic.  They do take a beating, exposed to temperature extremes and debris, and eventually they can tear or crack just because of their age.  Unless someone is keeping an eye on your ball joint boots, you may never know there's a problem.  That's why when ... read more
