2002 Santa Fe stick shift. Brought it in because all the windows ceased to move up or down and all the doors would not lock automatically. They said the window switch was damaged, so I paid for part and labor just for the window switch and it did not work. They then traced wiring and found the main dash switch chewed by rodents, Now they want to charge me an enormous amount for that, Shouldn't they have checked the wiring first? And what about the doors?
