Unlock the Secret (Malfunctioning Door Lock Actuator)

What a convenience power door locks are on a vehicle.  The latest don't even require you to push the button on the key fob; all you have to do is have it with you.  But sometimes there's a component of power door locks that can fail, especially when they are used several times each day.  Those are called the door lock actuators. The actuator is an electric part that works with others (like motors and gears) to lock and unlock doors.  You can hear them work, sometimes with the little whirr of the gear or the quiet clunk of the lock finishing its cycle.  And it's good to pay attention to that sound because if it starts to sound different, it could be a signal that your lock is on the brink of failing. Another sign of a failing power door lock actuator is they start working intermittently or quickly and erratically.  The driver's door is often the first to start acting up since it's the one that usually gets the most use. When you start to notice these signs ... read more

No Fueling Around (Fuel Filter Replacement)

A driver called in to the shop the other day saying his European sports sedan had an odd problem.  He was driving when his car started to slow down.  Applying more throttle didn't help.  He pulled over to the side of the road, shut the engine off and waited a few minutes before starting it up again.  It ran fine… for a couple of minutes.  Then the same thing happened.  He was able to finally get home by stopping and restarting, and he was calling to see if we could take a look at it.  Turned out it was one of his car's fuel filters that choked up with debris so badly that enough fuel couldn't get through it.  When he stopped the car, enough fuel could flow through the unpressurized fuel line to supply enough fuel for a couple of minutes when he restarted his car. But then the pressure would cause things to clog again.   There are other symptoms that point to a failing fuel filter. Perhaps your engine misfires, your vehicle is hard to ... read more

Keeping Your Cool (Coolant leak repair)

If there’s one thing you should pay attention to with your vehicle, it’s the temperature gauge. It’s the one that may say C---H (that means “cold---hot”).  Or maybe yours has a picture of a thermometer on it and a blue and red zone.  If you see the needle heading farther to the “H” or red area, that means your vehicle’s engine is running hotter than it normally does. One of the most common causes of an engine running hot is a leak in your cooling system.  Maybe you’ve seen puddles of coolant under your vehicle, or you’ve smelled the coolant, either inside or outside your vehicle (it has a sort of “sweet” or fruity smell). That’s your engine giving you a warning signal that it’s time to head over to your repair facility to find out what’s going on. Your vehicle’s coolant can leak for several reasons.  You may have hoses that are deteriorating (heat and age take their toll) ... read more

Steering You Right (Power Steering Fluid Service)

It’s important for safe driving that two of the most important systems in your vehicle work right.  One is the brakes.  The other is the steering.  Nearly all vehicles on the road have some sort of power steering that allows you to direct a very heavy machine with little effort.  There are two types, hydraulic and electric.  Many newer vehicles have electric power steering that uses an electric motor to make your steering easier.  But there are many vehicles on the road that use a system that has been around for years.  It uses a power steering pump, a cylinder, several valves, and hydraulic fluid to make it easy for you to turn the wheel.  If you have hydraulic power steering in your vehicle, it’s important to change your power steering fluid every once in a while.  Over time, the fluid gets contaminated with dirt and other particles.  You might notice your steering is loose, maybe harder to turn and makes a low, strainin ... read more

Move it or Lose It (Dormant Vehicles)

When it comes to your vehicle, driving it too much can cause some issues.  But what about not driving a vehicle enough? That has consequences as well. Here are a few things that can happen if a vehicle isn't driven enough.  When the engine doesn't operate, the oil isn't lubricating. That means some mechanisms that need periodic lubrication aren't getting it.  And oil that sits around breaks down over time.  In fact, some experts say you should change oil more often if your vehicle sits in the driveway than if you drive it regularly.  You've heard that expression, "Take it on the highway and blow out the engine.” Well, carbon buildup used to be a problem in older vehicles.  But the real culprit these days is moisture that builds up from combustion if your vehicle never gets hot enough to burn it off. That water vapor can mix with oil and cause sludge to form. There are many vehicle systems (battery, exhaust system, engine seals, etc.) that benefit fro ... read more

Pacific Highway Auto Repair Automotive Tips: Alternator

Your alternator makes electricity to start and run your engine and all of the vital electrical systems in your vehicle. That’s everything from the on-board computers to the turn signals. And of course there is the entertainment system, seat heaters, power windows and everything you plug into the power outlets. After your alternator makes enough electricity to do all that, it recharges your battery with what’s left over.When San Diego drivers constantly have a low or dead battery, the alternator is usually a prime suspect. However, the alternator is just one vital component of the starting/charging system, and a problem with any of the other components could be the actual cause.In addition to the alternator, the charging/starting system includes the battery, starter, serpentine belt system and all of the electrical cables that connect them. Your Pacific Highway Auto Repair service advisor has a systematic process of testing components and connections to get to the sourc ... read more

Braking Good (Brake Drum Replacement)

Maybe your vehicle feels like Breaking Bad.  In other words, when you brake, things are bad.  You may find it takes you a longer distance to stop, you feel a vibration, or it’s pulsating when you depress the brake pedal, or perhaps your vehicle pulls to one side. Those can be symptoms of failing brake drums.  While a lot more vehicles these days have disc brakes, many vehicles still have brake drums, almost always in the rear wheels. The drum is a cast iron shallow cylinder that surrounds the other parts, including curved brake shoes that press pads against the drum to slow you down or stop the vehicle. Any time you have things going wrong with your brakes, you should get them fixed soon.  Safely operating any vehicle depends on having the brakes be able to slow and stop you dependably.  It can make the difference between avoiding a collision and having one.  When you bring your vehicle in, a technician will inspect your braking system. Depending on ... read more

Pinch Petroleum Pennies! (Fuel Saving Tips)

If you saw a dollar bill on the ground, you'd pick it up, right? Well, whether you find that dollar on the ground or in savings at the gas pump, money is money, and here are some ways to hold on to more of it. Slowing down is the easiest way to save fuel, especially for every speed increase over 50 mph/80 k/hr.  Tone down the speed, turn up the cash savings.  Drive smoothly (not like a race car driver) and you'll also save money in fuel.  Aggressive, fast-start, jerky-stop habits are just pulling the bucks out of your wallet about a third more than if you drove just a little more gently.  Oh, and cruise control can help with that smooth, steady speed, so use it on the highway. Bonus! Are you hauling around a set of dumbbells or a box of books? That extra weight is costing you dough.  Store them somewhere else.  When's the last time you checked to see your tires were inflated properly? That's another money saver and makes your vehicle safer. An idle thought ... read more

No Fueling! (Fuel Filler Location)

If you've ever gotten in an unfamiliar vehicle, maybe a rental car, you may have pulled up to the gas pump and wondered, "Which side is the fuel filler on?" Here's a tip for you.  There is usually a little arrow on the instrument panel near the fuel gauge that points to the side where the fuel filler is.  But why are the fuel fillers not all on the same side, anyway? There are lots of reasons.  At one time, many manufacturers tried putting them in an easy-to-reach spot: in the center of the vehicle's rear end.  Some even hid them behind a hinged license plate door.  Cool place, but it turned out not to be a good idea.  When a vehicle with a fuel filler in the rear was hit by another vehicle from behind, it was much more prone to catch fire and explode. Safety regulations now dictate that the fuel filler doors be placed within crumple zones and away from where they can drip fuel on hot exhaust pipes or near electrical connections.  But why do manufactu ... read more

Visibility Disaster! (Windshield Washer Pump Replacement)

Let's say you live in a cold climate where the snowy, icy weather challenges you to clear the salt and debris tossed up on your windshield.  You push your windshield washer switch expecting a good stream of fluid so the blades can wipe the glass clean. Yet nothing comes out.  Nada, zip.  What's going on? You know you filled up the windshield washer reservoir within the last week or so.  Well, there could be a few things causing your windshield washing system to fail.  One culprit? The hoses that are supposed to carry that fluid from the washer pump to the spray nozzles may be frozen, or maybe they're cracked and leaking. It could be the nozzles themselves are stopped up, either iced up or jammed full of debris.  Your windshield wiper/washer switch could be worn out or the electrical system may not be conducting power to the washer pump.  It's important that this system work properly, especially on days when the sun may be in front of you and your wind ... read more
