Gen. light was on. Called them and dropped off van at 8 AM and by 2 PM they called and said that the Alternator had to be replaced but since it was under warranty there was no charge for the replacement.ant that technician fee was only a hour. this is a 96 Dodge van very close working space to get in and do anything. was really surprised when charges was only $69 and they had also done an oil change.
