    Possible Causes of a Headlight Relay Switch Problem

    Last updated 5 days ago

    Are your vehicle’s headlights, bright beams, or dash lights malfunctioning? Oftentimes when the activation, deactivation, or brightness of a vehicle’s headlights or dash lights is not working properly, there is a problem with the headlight relay switch. Usually this is caused by a loose or damaged wire connection, which an auto repair shop can easily tighten or replace. Another possible cause is a burned out solenoid coil, which simply needs to be replaced. A third possibility is that one or several switches can fail due to water damage, excess current, or corrosion. If only one headlight is not functioning, there is a chance that the headlight relay switch is working fine but that the bulb needs to be replaced.

    Understanding How Car Suspensions Work

    Last updated 12 days ago

    Many people do not think twice about their suspension system, until they are at an auto repair shop after a shock absorber failure. If you’re curious about how a car suspension system works, you have to understand the function of each part in the system. Read on for an overview of how the most important suspension components work.

    Chassis

    The frame of a vehicle carries the weight of the engine, transmission, and body. It is connected to the suspension system, which is engineered to support the frame even as it dives, squats, and sways with the motion of the vehicle. The steering system, wheels, and tires are connected to the suspension system, which allows the driver to manipulate the direction of the vehicle.

    Springs

    The coil spring is the most common type of suspension spring. Hooked up to the wheels, these springs compress and expand to absorb the movement of the wheels. Heavy-duty trucks use leaf springs, which are comprised of several layers of sturdy metal. The springs can be loosely sprung for greater comfort, or tightly sprung for greater control around corners.

    Dampers

    In a suspension system, the shock absorbers are one of the two primary dampers. Without shock absorbers, a spring will continually expand and contract until all of the absorbed energy from the road dissipates, causing the car to bounce down the street. Shock absorbers turn the kinetic energy of the springs into heat energy that can be dissipated using hydraulic fluid.

    Anti-Sway Bars

    The other primary dampening device in a suspension system is the anti-sway bar. The anti-sway bar is a metal rod that joins both sides of the suspension together. When the suspension at one wheel moves up, the anti-sway bar transfers the movement to the other wheel. This creates a more level ride and reduces vehicle sway during cornering.

    If your vehicle’s suspension system is experiencing problems, come to Walt’s Danville Service. We perform auto maintenance and repair services from suspension alignment and oil changes to transmission repair.

    The Science Behind Smog

    Last updated 18 days ago

    Smog is much more than just smoke and fog. In fact, it takes three things to create smog: normal city air, a type of vehicle tailpipe smoke called nitrous oxide, and sunlight. Many cities in California experience smog, in large part because of the large number of vehicles in the state and the relatively few days of rain. If you have a vehicle, going to an auto repair shop for routine vehicle maintenance will help reduce the amount of smog in your city. Watch the video to learn more about the science of smog.

    Top Signs Your Transmission Is Failing

    Last updated 24 days ago

    Your car’s transmission is one of its most vital mechanical components. Over the years, the many moving parts of your transmission will experience a great deal of wear and tear. By understanding the symptoms of a transmission problem, you will be able to schedule a repair appointment with your mechanic before it’s too late. To help you diagnose a potential transmission issue, here are some of the top signs that your transmission is failing.

    Trouble Shifting

    When a manual transmission is having difficulties, you may find that it is difficult to shift between gears. If your transmission is refusing to shift, you should schedule a transmission service appointment right away.

    Bad Odors

    If your transmission is in trouble, you may notice bad odors coming from underneath your hood. These burning smells could indicate that you are low on transmission fluid, which can cause your transmission to overheat. Your mechanic will be able to diagnose and repair a transmission fluid leak.

    Unusual Noises

    Your car’s transmission may make some strange or unusual noises when it is having troubles. You may find that your transmission is extremely noisy when you shift into neutral. In addition, you may hear grinding or thudding noises as you are driving down the road.

    Grinding Gears

    Grinding gears are a sign that your transmission may be in serious trouble. Over the miles, grinding gears could cause your transmission to fail altogether. If you are noticing grinding sounds as you are driving, you may want to set up an appointment with your repair shop.

    If your transmission is having problems, do not hesitate to contact Walt’s Danville Service. We serve the Danville and Pleasanton areas with a complete range of auto repairs, including brake repairs and check engine light inspections.

    How Are Smog Tests Conducted in California?

    Last updated 1 month ago

    Smog tests are required for nearly all cars in the state of California. If your car is due for a smog check, you may be wondering about what to expect during the procedure. A California smog check happens in three parts. First, a technician will visually inspect the vehicle to make sure that all of the emission control devices are properly working. Next, the technician will check the function of the gas cap and the check engine light. Finally, the car is placed on a device called a dyne. Once the car is on the dyne, the technician will take an emissions reading.

    If your car is in need of a California smog check, be sure to make an appointment at Walt’s Danville Service. Along with our smog tests, we can also assist you if your car is having trouble meeting emissions standards. To learn more about the great repair procedures that you can expect from our Danville repair shop, call us at (925) 394-7839.
