I bought my first ford dually yesterday, a 2000 F350 and I took the guys word for it. Both doors are dead, nothing works. He claims they worked then when he was detailing the inside they stopped so said it was a fuse. I looked all the fuses under the hood especially 25 and 26 and they aren't blown. Any ideas on where to go next? Kind of sux when you can't open your windows.
