If someone asked you what gas made up the largest portion of the atmosphere, what would you guess? Well, it's not oxygen; it only makes up 20.9 percent.  But since we're talking about oxygen, you should know that your vehicle uses oxygen sensors to make sure your engine is running the way it should. The oxygen sensors measure how much oxygen is in your exhaust.  If there's too much, it means there's a problem with the mixture of fuel and air.  The sensor sends signals to computers in your engine and adjusts the mixture so it maximizes performance and efficiency.  It does this constantly.  Many vehicles have multiple oxygen sensors.  Some have one close to the engine, another close to the muffler.  Two measurements are better than one since they allow readings to be more accurate.  You may have a vehicle with a dual exhaust, so you'd have twice as many oxygen sensors. Your oxygen sensors can fail.  One thing that can damage them is contaminat ... read more

The other day, a driver was trying to open his vehicle's hood so he could add some windshield washer fluid.  But when he pulled the hood release inside the car, nothing happened.  Usually, opening any hood is a 2-step process.  You pull the hood release (which is usually a handle under the dashboard to the left of the steering column) and listen for the hood to pop up slightly. (It doesn't open all the way because it has a safety latch to prevent you from accidentally opening it up while you're driving.) Then, you get out and find the latch, usually through the grille near the hood.  There's a little handle on it which you push, slide or pull (there are a few different types) at which point the hood can be opened up all the way.  But in this driver's case, the hood would not release at all when he pulled the handle inside.  Not knowing what to do, he called his service advisor, who told him to bring it over.  The reason? A hood with a broken latch cou ... read more

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 technic ... read more

You might remember a hit TV sitcom that was set in a bar, a place where "everybody knows your name."  The idea, of course, is people feel more comfortable where they aren't just another customer among many; they're special because their relationship goes back a few years.   That comfortable relationship can extend to professionals you deal with, too.  Think of your accountant, your dentist, your doctor.  Most people try to stick with the same person or firm in those businesses.  They have grown to know their work over the years and they've learned to trust their professionalism, the quality of their work and their track record.    Ideally, you should have that same relationship with your automotive service facility, like your friends here at Gordie's Garage Inc. You may have tried several facilities over the years until you found one that did good work at a reasonable price.  The longer your relationship with your service facility, the better the ... read more

It's pretty frustrating when your driver's window won't work.  You can't get your food at the drive-thru without opening the door, have a tough time using the ATM from your vehicle, can't have that fresh breeze blowing through your hair as you listen to your favorite road tunes. Plus, there's a safety factor.  Your windows provide an escape route in case you need to get out and the doors won't work.  Let's take a look at what's going on when your window won't operate. Most vehicles these days have power windows.  They have an electric motor in each power window and sometimes those fail.  They often give you a warning that they're on their last legs by making a noise or hesitating, so if you get a sign like that, have a technician check it out. Loss of power can also be due to a blown fuse, a bad switch or faulty wiring. All windows have something called a regulator that moves the glass up and down.  They have a lot of moving parts in them which can break ... read more

If you park your vehicle outside, you are exposing it to all sorts of critters that would love to use it for nesting, food storage and shelter.  There are plenty of pictures online of people who've discovered there was more than an engine under the hood.  In one case, the driver of an SUV started to smell a slight burning odor when she was driving.  Turned out to be 200 walnuts and a lot of grass had been stored there by some industrious squirrels preparing for the upcoming cold weather.  The SUV owners had their vehicle inspected not long before this happened, but it doesn't take some animals long to set up house in what they think is the ideal spot to make their winter home.   Obviously, that can create problems.  Squirrels, mice, rats and other small animals can chew through hoses and wires.  Plus what they store as food and nesting material may prevent engine parts from moving the way they are supposed to.  Imagine a radiator fan that wo ... read more

Engines required a lot more maintenance in earlier times.  You'd have to have your spark plugs, wires, rotors, caps, distributor points, fuel and air filters changed periodically.  There were mechanical adjustments of a vehicle's timing, dwell, spark gap and idle mixture, too. Unless you like to tinker with old cars, a lot of those terms won't mean much to you.  That service was called a "tune up" back then, and you can see why.  But now, computers have reduced the number of maintenance items, and a tune up is a whole lot different than it used to be.  In fact, in some vehicle service facilities, that term is also a thing of the past.  A tune up of today would more accurately be called simply periodic maintenance. Now, most vehicles still have spark plugs and wires, fuel filters, air filters and PCV valves, and they should be inspected tested and/or replaced at regular intervals.  Your vehicle's manufacturer has made recommendations on how often that ... read more

Most people don't love going to get their vehicle serviced, but it's one of those things you just have to do. So you might as well get the most of out of it. There are some steps you can take that will likely help you get the best results possible. For one thing, it's important to describe your problem (or problems) to the service advisor accurately and clearly. If your vehicle is making a noise, for example, take time to really listen to it and think of the best way to describe it. Does it increase in speed when you go faster? If you feel a vibration somewhere, where in the vehicle does it seem to originate? Some service advisors recommend writing things down. That way the driver won't forget any important clues that could lead to a successful resolution of the problem. Another thing is to make sure your vehicle is cleaned out and free of junk. That way the technician can access those nooks and crannies where some vital components may be. If your vehicle is full of strollers, boxes or ... read more

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another words that begins with S.  Sulfur. Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should.  That could be due to age, damage or an abundance of oil that's clogging it up.  If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe. There's another possi ... read more

You know you have an accelerator pedal; step on it and your vehicle is supposed to go.  But did you know there is a part in your vehicle that keeps track of where the throttle is? It's called the Throttle Position Sensor, or TPS. The TPS is a sensor that helps your vehicle figure out the right mix of air and fuel is reaching your engine.  It does that by keeping track of the throttle and sending that information to your vehicle's computer.  Other factors play a role in how well your engine is performing, including air temperature, how fast the engine is turning over and air flow.  When the TPS isn't working right, you may find your vehicle won't accelerate or doesn't have the power you're expecting when you press on the accelerator.  In some cases, it may accelerate on its own.  Sometimes your vehicle won't go over a certain speed.  Your Check Engine light may go on. Any of these symptoms should be checked out soon.  If your TPS stops working rig ... read more
