"Current" Affairs (Blown Fuses)

You may be driving along and find that suddenly your radio stops working.  There are no numbers on the display.  Then when you get home, you notice the garage door opener doesn't do a thing when you press the button. Hmm, this was working just fine this morning.  Are the two problems somehow related?   No, your vehicle doesn't need an exorcism. This has all the signs of an electrical issue, and when you experience symptoms like those, you've probably blown a fuse.  Most vehicles have fuses just like most houses have circuit breakers (some houses still have fuses). They cut the power when it reaches a pre-determined threshold that could cause major damage if it was allowed to continue.  You might say fuses take one for the team.

What Is That? Check Engine Light Service at John's Automotive Care

Okay. You went to your local San Diego car wash, and while your vehicle was under the dryer, the Check Engine light started flashing. Panic! What did you just do? Something is seriously wrong with the vehicle! You head for the nearest San Diego service center, but on the way, the Check Engine light stops flashing and just glows red. Hmm.

You decide the light must be faulty; maybe when it comes on it doesn't mean anything, or maybe it's just in your vehicle as some sort of scam to get you to pay for unnecessary repairs. You're glad you didn't take your car to the San Diego repair shop and resolve to ignore that Check Engine light in the future.Whoa! Let's look at what really happened. Your vehicle was under an air dryer. Your air intake sensor measured too much air running through the engine. It sent its ... read more

Automobile Fluids For Your vehicle

If you've walked through the automotive fluids section of an auto parts store in San Diego, you'll know how overwhelming the sheer number of products available can be. How do you know what's right for your vehicle?As you know, these fluids all serve a function in making your car run as you drive around the San Diego area. Your vehicle manufacturer has specified a particular type of fluid for every system from the motor, to the cooling system, brake fluid and so on. When you realize that not every variation is applicable to your vehicle, the task becomes more manageable.First let's talk about why there are so many varieties. Starting with motor oil, we see that manufacturers match the properties of a particular weight or type of oil with the design needs of the engine. For example, engines with sophisticated valve trains often require a thinner weight of oil.Some vehicles around San Diego come from the factory filled with synthetic oil a ... read more
