My check engine light came on so I stopped in Advance Auto Parts, an associate come out with their computer and plugged it into my car, he give me the computer codes of the problems with my car. I searched Google with these codes and got plenty of information from Blogs and Car sites of what my problems were and how was the best way to fix these problems. While there and feeling like their employee really cared, I asked about a inexpensive par of windshield wipers, he hooked me up and even gave me a quick tutorial on how to install them, even offered to come out and put them on for me. Thanks AAP, keep your employees happy and your customers will be happy too.
