A Honking Big Jam (Stuck Horn)

At one time or another, most drivers honk their horn at someone who might be texting at a stoplight or not paying attention when they're driving.  But what happens when you tap on your horn and all of a sudden it won't quit? Everyone's looking at you like you're an angry jerk and all you want to do is turn it off!

It helps to know the basics of what's happening when you honk your horn.  There's a switch in the steering wheel, of course, and when you press on it, it sends power to a relay which then energizes the horn.  Bingo.  Sound.  When the horn sticks on, one of these parts or the wiring has developed a problem. 

With the ear-splitting noise inside your cabin, it may be hard to keep your cool, but do your best to stay calm.  Try pushing the horn several times; it may un-stick the switch if you're lucky.  If not, there are a couple of things you can try.

First, if you can, pull your vehicle off the road and into a spot where you're not disrupting traffic.  If you feel comfortable rummaging around in your vehicle's fuse box, you might be able to pull the fuse that manages the circuit for your horn system.  A hint: the fuse boxes sometimes have a label inside showing which fuse goes to which part of the vehicle. Find the fuse that goes to the horn and pull it out (sometimes there's a fuse-pulling tool inside the fuse box).

But many people don't feel like tackling that.  Yes, you can drive over to a service facility with the horn blaring (not the best idea).  Or call your service facility and see if they might be able to send someone over to where you are so they can shut off the horn.

At the shop, a technician can check wiring, switches, relays and other components to find out what's wrong.  This is something that should be left to a professional for a couple of reasons.  First, repairs around the steering wheel can involve airbags.  Second, some horn components may be part of a vehicle's alarm system. 

The bad news is that your horn may not give you any warning before it starts blaring uncontrollably.  But the good news is that a horn doesn't malfunction all that often, and now you have a plan if it does.

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.

When Metal Meets Metal (Wheel Bearings)

What part of your vehicle has little metal balls inside that are lubricated and allow you to cruise on down the road?  They are wheel bearings, and automotive designers might argue they are human beings' second greatest invention of all time (the first is, of course, the wheel!).

You have a wheel bearing at each wheel.  They allow your wheels to turn freely, minimizing friction that would ordinarily slow you down when metal meets metal.  When one of your wheel bearings starts to go bad, it lets you know. A wheel bearing does its work quietly when it's in good health but starts getting noisy when it isn't.  People describe the noise differently.  Sometimes it sounds like road noise, a pulsating, rhythmic, sound.  That pulse speeds up when your vehicle speeds up. 

Here's what's happening when you hear that sound.  As mentioned, the bearing has these little metal balls inside a ring.  They have a lubricant inside to reduce friction between the balls; modern wheel bearings are sealed and they're intended to do their job without any maintenance. 

Wheel bearings take a beating; you hit some rough potholes or go over some uneven railroad tracks. Sometimes water can get into a bearing and reduce the ability of the lubricant to do its job.  Time starts to take its toll, too. When the lubricant isn't reducing friction like it should, the bearing can heat up. One of those little balls can start shedding pieces of metal and soon those shards start grinding up the other balls.  Friction takes over and soon your wheel isn't turning smoothly. That's what's causing the sound.  If a wheel bearing is not fixed, it could eventually seize up completely, and you can be stranded.

It's a lot easier if you heed the early warning signals, that pulsating noise.  Now, sometimes a similar noise can be caused by a bad tire, but in either case, it's important to have it checked out. Our Joe D'Auria's Auto technicians will be able to tell you fairly quickly what the problem is and offer a solution.

Wheel bearings generally don't fail often and usually last from 85,000-100,000 miles/140,000km to 160,000km. But consider them a long-term maintenance item that, once fixed, will keep you heading smoothly to the next destination.

Beware of Potholes! (Avoiding Pothole Damage)

You may live in a region where roads become pockmarked with craters known better as potholes.  They're caused by moisture seeping through a compromised road surface that can freeze, expand and literally punch holes in the road.  And when your vehicle hits one of those holes that's big enough, the impact can flatten a tire, bend a wheel or tear apart a suspension component. 

To minimize pothole damage, leave enough room between you and the vehicle in front of you so you can see the road surface and any upcoming potholes.  That way you'll have time to slow down and steer around them.  Also, if you see what looks like a puddle of water, it may be hiding a pothole underneath, so treat it as if was a pothole.

If you keep your tires inflated to the manufacturer's specifications, they're more likely to withstand hard impacts.  And the slower you're going when you hit a pothole, the less likely you are to break something.   But if you do find you've hit a pothole pretty hard, here are some signs to watch out that could signal damage.

• Your vehicle pulls to one side
• The steering wheel shakes
• You hear noises or clunks coming from your suspension
• Your steering wheel is not centered when you are going straight

These are all symptoms you should have checked at your vehicle repair facility as soon as you can. The longer you wait, the more damage you may be doing.

You also may find after hitting a pothole hard that the tire on that wheel is flat. Try not to drive any more on that tire since you could do a lot more damage to the tire and/or wheel. A call to roadside assistance may save you money in the long run by limiting the damage to what's already done.

Bad Vibes

Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something.

There are a few things that can cause your steering wheel to vibrate as you drive down the road.  One of the most common is out-of-balance tires.  You may not only feel that wobble in your steering wheel, you might also feel it in the tires.  Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds. 

So what is tire balance anyway?  Well, you have a rubber tire that fits around a metal wheel.  It should have the same weight all the way around.  If it doesn't, it will start getting the shakes.  Ever load your washing machine so that all the clothes are at one side of that drum that spins?  When it hits the spin cycle, it can throw that washer against the wall. 

That's the same thing that's happening with an out-of-balance tire/wheel combination.  A technician has special equipment to figure out where to put small weights on the wheel to get things back in balance again.  But it could be that you hit a pothole some time ago and bent the rim.  Or your tire isn't as round and even as it once was.  That could be due to age, damage or wear and tear. The technician will know and offer you options.

Another possibility for that vibrating wheel is a faulty brake, such as warped rotors or a sticky caliper.  All of these issues can be evaluated as part of regular, routine maintenance with us.  There are many things that cause vibrations in your wheels.  But you don't want any bad vibes when it comes to your vehicle.
