McPherson Automotive Automotive Tips: Diagnostic Service

Imagine waking up one morning with a stomach ache. You pick up the phone, call the doctor’s office and say, “I’ve got a really bad tummy ache. How much will it cost to make me feel better?” Of course you wouldn’t do that. You know that there could be a lot of reasons for your symptoms and that the doctor will have to examine you, ask some questions and probably run some tests before she can tell you what’s wrong and give you treatment options.

This same scenario plays out every day at IL auto repair facilities. When the cause of the concern isn’t obvious, the car will need to undergo a diagnostic examination. The typical car has about 30,000 parts, including several networked computers and miles of wiring. Finding exactly what is wrong can be very complicated and take some time. The most experienced technicians at McPherson Automotive in Du Quoin are the ones who tackle the difficult diagnostic jobs. Once they have determined the cause of the trouble, they can work out the plan for how to fix it and tell you how much it will cost.

When you think about it this way, it makes perfect sense that, 1) the McPherson Automotive service advisor cannot provide an estimate before the diagnosis is done, and 2) there is a charge for auto diagnostic services in Du Quoin. You expect to pay for an office visit to the doctor and for any necessary tests before you can be presented with your treatment options and costs; same goes for your vehicle.

We know it can be frustrating for Du Quoin drivers when something is wrong with your car and you aren’t sure what is going to be involved in getting it fixed. We are passionate about helping you through the process, communicating with you at each step along the way.

Catching Trouble Early

Your vehicle depends on wheel bearings.  Sitting between the wheel’s hub and axle, they allow your wheels to spin smoothly, bear the vehicle’s weight and work in harmony to stay aligned with other parts.  

Wheel bearings can fail in several ways, and they may send the driver some pretty clear clues.  Sometimes they make strange noises, or you may feel vibrations instead of the usual smooth ride. The most common signs are grinding or humming noises, uneven tire wear and steering vibrations.

Wheel bearings can fail when they are contaminated with water, road salt or dirt that slips in through a broken seal that’s designed to keep those things out.  If lubrication gets too old or overheats, it can create friction and heat that will cause the bearing to fail.  If you’ve hit some hard potholes or curbs, that can also damage a wheel bearing.

Unfortunately, wheel bearings can’t be fixed; they have to be replaced.

Once a wheel bearing is worn, replacement is the only fix—bearings cannot be repaired. When you bring your vehicle in, a technician will give it a road test and listen for noises on turns.  If your bearing needs replacing, the technician will use the appropriate part for your vehicle and make sure the axle nut is torqued to factory specifications.

If you can avoid driving in deep water, keep your tires balanced and make sure your suspension and brakes are maintained, you might minimize the chances of damaging a wheel bearing.  

You probably don’t think about your wheel bearings very much, but they are important to good vehicle performance.  When they’re healthy, your wheels will rotate smoothly, handling will be stable and your braking will feel solid and predictable.

A Non-Starter (Alternator Problems in Cold Weather)

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.

In a Fog (Fogged Windows in Cold Weather)

It's bad enough in cold weather when ice and snow block your visibility.  Add to that fog on the inside of your windows and you could be driving blind.  So here are a few tips on how to keep your windows from fogging up when there's a chill in the air.

You probably know fog is really condensation, when moist, warm air meets a cold surface and turns to liquid.  If your windshield fogs up, you probably turn on your windshield defroster. Most defrosters blow heated air on the windshield glass to warm it up so it won't condense the moisture.  Many also turn on the air conditioning to reduce the moisture. 

That same strategy can work on the rest of the windows.  First, turn up your heater's temperature setting.  The hotter the air, the more moisture it will hold.  Also, turn off the "recirculating" setting since you want all outside air to come in. Then switch on the air conditioning.  It will remove the moisture from the outside  air that it's blowing inside the cabin.  Try cracking a couple of windows to make it easier for the air to flow. This should do the trick pretty quickly. 

There's one other thing to try.  Many vehicles have electric heater elements embedded in the rear window glass (the rear window defroster) and in the outside rearview mirror glass. Make sure to turn those on, too; sometimes they're on the same switch.

For all of these things to work, of course, your vehicle's components have to be maintained so they'll do the things they're designed to do.  And you didn't think it was important to have your air conditioning working in the cold weather months! 

One final tip.  Keep the insides of your windows CLEAN.  Oil and dirt on the glass give the water molecules something to latch on to.  That ought to clear up this problem.

Du Quoin Drivers: Get Fresh Air Inside Your Car

Let's talk about air quality in Du Quoin. It's a global issue, but affects us wherever we are. Many decades ago, Du Quoin drivers began to become aware of how air pollution negatively affects health. But what about the air inside your vehicle?

Now, it's only been in the last few years that cabin air filters have become common in Du Quoin. You can look in your owner's manual to see if you have one. If you do, there'll be a recommendation for replacing it when it gets dirty. If you live in an area of IL where there's a lot of dust, pollen or pollution, you may need to change it more often.

You can also ask your friendly and knowledgeable service advisor at McPherson Automotive in Du Quoin. How hard is it to change an air filter on a car? It depends on your vehicle. Some are quite accessible; others take some doing to get to them. They're usually in the engine compartment or under the dashboard.

Because cabin air filters are so new on the scene, some people haven't heard of them – even those who have cabin air filters in their vehicle. McPherson Automotive service advisors have discovered that many Du Quoin customers who complained about an unpleasant odor in their vehicle simply had a dirty cabin air filter.
