What Ashman said is so true!!! Last summer I took my car to Sears because I thought that something was wrong with the battery when the light kept coming on. Come to find out that it was the alternator. Sears tried to tell me that I need a new alternator and that it would cost me about $340. I said there was no way they were touching my car to do anything but rotate the tires or to swap out a battery. So I drove the car to my mechanic where he rewound the alternator brushes for a total of $50. I have learned the hard way over the short few years that I have had to deal with car repair shops that they will try and get as much money out of you as they can (except my mechanic, of course!!).
