It's happened to all of us. We're driving down a highway at night and over a crest appears a car with its high beams blazing. You are momentarily blinded, hoping the other driver will switch them to their low beam setting and restore your vision. Not only do we not appreciate being blinded, face it; we don’t want to be that other driver, either. You know, the one who forgets to turn down their high beams. Why do we want high beams in the first place? They can improve safety when used correctly, giving drivers more reaction time since they can see farther down the road. But research has found many drivers either don't use them or, when they do, they frequently forget to switch to low beams. Enter the automatic high-beam dimmer. The quest for the perfect one began back in the 1950s, General Motors invented something it called the "Autronic Eye." It was a phototube which sat on the dashboard and turned down your beams when it saw other headlights.  ... 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

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

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
