Stopped at Advanced Auto on S. Locust to use code reader on car to see why the check engine light was on. Went into the store and it was like a ghost town, no customers and no employees visible. After making a lap around the store I had to twice tell an employee sitting on a bucket stocking shelves, "Hello" to get her attention. I asked if she had code reader as I had light on in my car. She handed me the code reader, I advised I had never used one and not sure what to do. She told me there was a plug in under my steering wheel, just plug it in. Went out to car, plugged it in and nothing happened. I went back in telling her that it didn't do anything and asked if there was a button to turn it on, again she said just plug it in. At this point, I was feeling like I was bothering her and I should be able to figure this out. So went back out to car and used YouTube. Well, you are supposed to turn car to accessory, plug in reader and it should read. If not, start the car and then it will read. Nope, reader still didn't turn on. So I went back in and asked if someone was available that could try. Even though no customers were present, some gentleman came from the back grumbling about just plugging it in. Turns out I am not a complete idiot as he thought, because it didn't work for him either. He said to go try O'Reilly's down the street and if theirs didn't work, it was probably something wrong with my plug in. Well, that store was not anymore helpful, so I found myself at Auto Zone ready to take on the world when an employee mentioned that it could be a fuse. So I grabbed the car manuel and figured out what fuse, found the fuse in box under the hood, located and found the burned out fuse. Went into this third store, found the fuse by myself, bought it and replaced. Amazingly enough, the code reader worked!!! The employee at Auto Zone did a great job of answering all my questions about the codes my car threw and gave me printout showing me parts needed and cost of them. With my new found mechanic confidence, I need to decide if I am up to replacing my own O2 sensor..... read more
