Why does my Heat/AC only run on one setting?

Why does my Heat/AC only run on one setting?

The blower motor powers the fan that allows hot or cold air to flow from the vents in your vehicle. It is the life of your HVAC system. Without airflow, you won’t have properly working heat or air conditioning. The blower motor is inside your dashboard, usually opposite the steering wheel. So, what does the blower motor have to do with a fixed high airflow? The blower motor works in conjunction with a resistor. The resistor uses voltage to control the output speed of the blower motor. The blower motor resistor is prone to shorts, corrosion, and overheating. When the resistor fails, typically, the highest setting is the only option that still functions. This is because the air from the blower motor is bypassing the resistor, thus gaining the maximum amount of voltage, resulting in full power. In other cases, there could be an issue with your AC module or the fan switch. With the resistor sometimes located in a hard-to-reach location, it’s best to go to a trusted auto shop ... read more

Why does my sway bar link break?

To figure out why your sway bar link breaks, it's first important to understand how sway bars work. The sway bar, also known as an anti-roll bar or stabilizer bar, is a vital part of your vehicle’s suspension system and keeps it level during cornering. Sway bars are usually a long and hollow arched steel bar attached to the chassis, connecting the left and right sides. This stabilizes your vehicle while still allowing the suspension to move on its own. Sway bar links are what connect the outer end of the sway bar to the suspension component. Because the sway bar itself is a torsional swing, the sway bar link smooths the motion transfer between the sway bar and the control arm. The sway bar link maintains the camber angle of the inner wheels to control motion. Like many automotive parts, over time the sway bar links will wear out. Water intrusion that leads to rust, age, and lack of lubrication all contribute to deterioration over time. A knocking noise from your suspension, rattling ... read more

Signs of a bad water pump

Signs of a bad water pump

The engine of your car creates an insane amount of heat. The water pump runs coolant through the engine block, radiator, and hoses to draw heat away from the engine to keep it cool. Running coolant through the engine is vital to keep your engine running smoothly at the optimal temperature. While sturdy, like most parts, over time, the water pump will wear out and need replacement. So what are signs to look for in a bad water pump? The most visible method would be to check the front of your car for a coolant leak. The water pumps made from various seals and gaskets will dry out and crack over time. These cracks and tears will allow coolant to leak from your vehicle. If you notice orange, green, or red fluid under the front center of your vehicle, it may be a sign of a possible leak. It's important to note that a small leak will create rust or a buildup of gunk and minerals leaking to corrosion. This could be another sign that it's time for a replacement. Several things may ca ... read more

What is a brake booster?

What is a brake booster?

The brake booster is a canister that sits between your brake pedal and the master cylinder. Much like power steering helps us steer, brake boosters help us in the braking process. Some breaking systems work at high fluid pressures, this has the ability to make our brake pedals hard to use. Brake boosters make this job easier. When you press your brake pedal, the booster supplements the force put on the master cylinder. Brake boosters contain a diaphragm that separates the inside into two parts that are both in a vacuum. As you press your brake pedal, it causes a valve inside of the brake booster to open, which allows air into one side of the booster. The difference in pressure on one side pushes the piston inside the brake master cylinder forward from the pressure in the pedal. This action is what assists your vehicle in coming to a complete stop. Without brake boosters, we would become exhausted from driving just from having to mash the pedal! Bring your vehicle to Ferber’s Ti ... read more

Why does my catalytic converter overheat?

Why does my catalytic converter overheat?

A combination of air and gasoline is forced into a combustion chamber where they’re burned and let out into the environment. Your vehicle’s exhaust emits toxic chemicals that pollute the atmosphere. This is where the catalytic converter comes in. The converter uses a catalyst that causes a chemical reaction. This reaction converts the harmful compounds into harmless compounds. So, what causes your catalytic converter to overheat? There are a few factors that can be the underlying issue. Leaking fuel injectors can cause unburned fuel to burn inside of the converter instead. The extra fuel melts and overheats the substrate. When there is too much air in the combustion chamber a misfire can occur. This is called lean burn. Misfiring causes extra hydrocarbon buildup in the converter. This build-up will clog your converter and cause it to overheat! A failing oxygen sensor is an oft-overlooked cause of overheating. Your converter links to oxygen sensors in your vehicle. These ... read more
