If your car horn is not working, take a few minutes to go over these common problems and what you can do to fix it yourself.
The most common problems that will cause your car horn not to work are either the horn itself is bad or the clock spring mounted behind the steering wheel is bad. When the clock spring is bad it is very likely that your airbag or SRS warning light comes on at the same time.
Why your car horn is not working:
Do you hear a hissing noise coming from the brake pedal? The noise may be there constantly, or you may only hear it when you press the gas pedal.
If you hear a hissing noise from under the dashboard that changes when you press or release the brake pedal area, it most likely is a brake booster that is failing.
In this article, we go over the procedure on how to change the engine oil in a car. We drain the oil from the oil pan and change the filer as recommended by most car manufacturers.

Wheel bearings can make various noises when they are failing, but one of the more common ones is an unnerving whirring/grinding noise as you accelerate. The sound may be there all the time or only when you are making a turn.
One of the most common problems with CV joints is when the protective boot gets broken or cracks which leads to CV joint failure. As grease leaks, dirt and moisture will enter the CV joint. This will cause the CV joint to wear faster and fail due to lack of lubrication and corrosion.
One of the most common symptoms of a bad CV joint is the click, click , click sound when turning. The same sound will be noticed under heavy acceleration as well.
In this article, you will learn how to check the charging system on a vehicle. This procedure allows you to test the car battery and alternator.

There are many components that can cause vibrations in your car. In this article, we will look at some of the most common problems that will make your car shake or vibrate.
Causes of vibration can be anything from steering system, driveline, engine or the suspension system.
The suspension system which can contribute to vibrations consists of a series of arms, rods, ball joints, bushings, wheel bearings, steering knuckle, and strut.
All of these components together amplify vibration when one or more components start to fail.
In this article and video, we explain the signs of bad engine mount (may also be referred to as motor mount). An Engine Mount is a rubber and steel component that prevents excessive engine movement during driving or reversing.
The purpose of the engine mount is to absorb engine vibration, engine torque and also support the engine.
Also, it allows the engine to flex to a certain degree but not so much to the point it put stress on the transmission and drivetrain. In this guide, you will learn how to check if your engine mounts are bad.
Is your car making a strange noise when driving, braking, turning or at high speed?

The check engine light can come on for a number of reasons ranging from a loose gas cap to bad spark plugs or even due to a serious engine or transmission problem.

Oxygen sensors are very easy to replace as long as they are not rusted and are easy to access. Once rust sets in, an oxygen sensor can be difficult to get loose and remove. In this article, you will find a few tips on how to remove an oxygen sensor.
How to remove/loosen an oxygen sensor
It is very important to use the proper oxygen sensor socket for your particular vehicle. Some cars require special oxygen sensor tool to remove them.
A sway bar (also known as a stabilizer bar, anti-roll bar, anti-sway bar) is used to keep the car body from leaning excessively to the side. Stabilizer bar bushing and links can be easily checked.
If you notice that they are loose or have any play they need to be replaced. The sway bar itself almost never gets damaged, it is the sway bar bushings and sway bar links that wear quite often, sometimes as early as 60,000 miles.
