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.

Shifty Letters PRNDL (Transmission)

You probably figured out those shifty letters.  They're what you see on your automatic transmission shifter and stand for Park, Reverse, Neutral, Drive and Low.  Your automatic transmission is one of the great automotive inventions; here are some ways you can keep yours working well.

Maintain your transmission regularly.  A technician will check your transmission fluid's level and even its appearance and smell.  If it's dark or has an unusual odor, that could be a sign of trouble.

Change from one transmission direction gear into another only when your vehicle is stopped.  So many drivers want to switch from Reverse to Drive quickly or the other way around.  If you do that when the vehicle is moving, you can damage your automatic transmission.

Keep your vehicle's cooling system in top shape.  What does the cooling system have to do with the transmission? It helps keep the transmission fluid from overheating. 

Follow the manufacturer's recommendations for maintaining your transmission.  Some recommend at least an annual checkup by a trained technician. 

Let your powertrain warm up a little before overtaxing it. Especially in cold weather, don't step on the throttle too aggressively before all components are warmed up.  That way both your engine and transmission will last longer.

Transmissions can be costly to fix.  If you treat your powertrain with respect and regularly maintain it, you'll not only avoid expensive repairs, but you’re also much less likely to find yourself stranded because of a transmission problem.

Always on Guard (TMPS)

One of the most important things you can do to keep your vehicle running safely is to make sure your tires are properly inflated.  If one or more is vastly over- or underinflated, that has the potential to cause major handling problems and may result in a dangerous accident.

All vehicles in recent years are equipped with Tire Pressure Monitoring Systems, or TPMS.  One system uses small sensors in the tires that continually check the pressure in each tire.  That sensor sends a signal to computers in your vehicle which turns on an instrument panel light warning of low pressure when at least one is very low. Or it may update a numeric reading on your instrument panel which gives you an approximation of how many PSI (pounds per square inch) of air is in each tire. 

Another system works with your antilock brake system to measure the size of your vehicle’s tires.  When one wheel is going faster than another, it will spin faster. A computer sees that and alerts you that tire’s diameter is smaller than the others and therefore must be underinflated.

No matter what system you have, it’s also helpful for you to know how much pressure each tire is supposed to be inflated to.  You can find that on a label on the driver’s side door sill. In addition, the TPMS system should not be used as a substitute for checking your tires with a tire gauge since the TPMS accuracy usually isn’t quite as precise.  Keep in mind that tire sensors can fail, so each system acts as a backup for the other. 

Since many vehicles these days don’t have spare tires, it’s good to know that your TPMS can warn you if you have a leak in one of your tires.  If you get a low-pressure warning, many systems will tell you which tire is low, so you can do your own visual check.  Often you can see if you’ve picked up a nail or a screw if it’s sticking out of the tread or near the sidewall.

Being able to receive an early warning from your vehicle of abnormal tire pressure may give you a chance to safely drive to a service center before your tire slowly goes completely flat (which can ruin the tire and badly damage the rim). It also may ultimately prevent you from being stranded somewhere with a flat tire or, most importantly, having a sudden blowout on the road.
