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

This may have happened to you. You drive somewhere and get out of your vehicle only to try closing the door and it just won't stay closed! What a helpless feeling. You can't lock it; you can't leave it like it is. Or, let's say you head down to your vehicle to head out to work in the morning and you can't open the door. What are you going to do now? Vehicle doors take a lot of abuse. They are opened and closed hundreds of times and we expect them to just keep working perfectly all the time. They do require a bit of tender loving care. Let's take a look at two different scenarios of stuck doors. First: the door that won't close. It's a security issue. It's also a safety issue. You can't really safely drive a vehicle with a door that won't close. What if you or a passenger is tossed out? Sure, some people try to tie a stuck-open door closed or bungee it, but that's dangerous. It's best to get that vehicle to the serv ... read more

Your vehicle is like you in a way. When it gets hot, it needs to be cooled down. And one of the key parts to keeping it cool is the water pump. Now, that's a bit of a misnomer. It IS a pump, but it's pumping coolant, not pure water. Cooling off your engine is vital since it builds up heat when it creates power by burning fuel. Your water pump acts as a way to recirculate that coolant. It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat. Cooled off, the coolant is recycled through the water pump to start the journey again. The water pump works by taking mechanical power from the engine, usually from a belt. Obviously, that belt has to be in good condition and adjusted properly or else the water pump won't be able to do its job. Here are some things to look for that will signal problems with your water pump. If your heat gauge is erratic or sho ... read more

In many places, license plates have to be renewed every year or else you can't drive your vehicle legally. Usually, you'll get a reminder from the agency that issues the plates. That kind of regular attention needs to be paid to your vehicle as well. Its manufacturer has determined a schedule of service items that need to be done regularly, just like renewing your plates. Some depend on time, others depend on distance. A perfect example is oil changes. It's the most important scheduled maintenance you can have done to give your engine its longest life possible. The manufacturer recommends the oil filter be changed at the same time. Here are some more items. Your engine air filter gets dirty and needs adequate air to run most efficiently. The manufacturer recommends an interval for replacing that. Also tires, brake pads, timing belt, oxygen sensor and other items require regular replacement. This is one of the reasons to find a servi ... read more

If every road was straight and smooth, we wouldn't have to worry much about wheel alignment. But they're not, so we do. Hitting potholes or driving on rough pavement can knock your vehicle out of alignment and you'll notice it in one of several ways. Your steering wheel may not be centered when you're driving straight ahead, or your vehicle may pull to one side. You may find your tires wearing on one side or they may squeal. All are signs that could point to you needing an alignment. Your wheels should be perpendicular to the road and parallel with each other. If not, your tires will wear out faster and your vehicle won't go straight on a level straightaway. In alignment, there are several factors that must be checked. One is camber. Your wheels should be straight up and down if you look at them from the front. If not, you'll wear your tires unevenly on one side. Another factor is caster, the angle of the steering pivot. Most vehicles have what ... read more

When someone mentions driving like a maniac, they're not talking about you, surely? Besides the safety issues of aggressive driving, you should know that your vehicle will last a lot longer if you'll just mellow out a little. Here are four traits good drivers follow if they want their vehicles to go the extra distance. Cool—The driver who can't wait to get to the next stoplight is just shortening the life of his or her vehicle. Jackrabbit starts and uneven acceleration hurts your engine because the valves and cylinder heads are stressed more. All of those moving parts will wear out faster as well as other components that are connected. That means things like the air conditioner, power steering pump… just about anything that attaches by a belt or a pulley. Oh, and you'll be generating more heat. Heat is one of a vehicle's worst enemies. Warm—If you get in your cold vehicle which has been sitting overnight, start it up and rev the en ... read more

Ever wonder why it costs so much more to fix a similar problem in two different vehicles? Let's say you now own an SUV and before that, you owned a car. Your SUV's air conditioning system needs a new evaporator, but the cost for the new one is way more than you remember it was for your car. How can there be that big of a difference? There are many reasons. For one thing, vehicles aren't all the same. Yes, they have engines and steering wheels and suspensions, but engineering and design can vary widely among different styles and brands. In the case of replacing the evaporator, the one in your former car may have been located in a spot where the technician could get to it easily. Plus, the part may have been less complicated and, therefore, cheaper. Your SUV may require the entire dashboard to be removed with special tools to detach the a/c lines from the evaporator. Plus, since it is supplying cool air to a bigger cabin, it may be more com ... read more

As the weather changes over from hot to colder, drivers will have to deal with more slippery streets. And it's important to know how to drive with the brakes you have on your vehicle. In the 1970s, anti-lock braking systems (ABS) started to be installed on vehicles and they've been a game changer for drivers. Most modern vehicles have ABS and it's important to know how to drive with them. In older vehicles without ABS, the driver applies the brakes by pushing down the pedal. That, in turn, sends braking pressure to all four wheels at once. But all four tires don't have the same traction because the road surface they're each on isn't exactly the same. ABS allows sensors to determine when particular wheels are slowing down more quickly. The ABS then reduces braking pressure to the wheels that are about to lock up. That way the wheel turns and the tires keep some grip. (You have to have grip to stop.) It's kind of what drivers try to achieve when ... read more

There's nothing like that sinking feeling when you turn the key and nothing happens in your vehicle. A lot of us are quick to blame the battery. But it may instead be your alternator that's failing. Your battery supplies power to start your vehicle, but the alternator is what sends power when your engine is running. The good news is alternators last a fairly long time, and it's not unusual to get seven years out of one. But they can give up the ghost thanks to the harsh conditions in the engine compartment. Alternators have bearings inside them that keep things turning smoothly. Debris, liquid, dirt and more can team up with the high temperatures your engine generates to cause those bearings to seize up. That's not good, and if that happens, you may even be able to hear the bearings grind. Other symptoms of a dying alternator are a squealing noise in the engine compartment or your headlights may go dim and bright, dim and bright. You might even notic ... read more

You probably never thought about it, but your vehicle is like a rolling weather station. It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool. First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in. Some of those sensors can control computerized systems in your vehicle to react to the weather. It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle how those sensors will respond. Let's start with temperature. Most vehicles now have a thermometer that measures the temperature outside. It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures. But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning. If your ambient tem ... read more
