VIN number Invalid
When I contact Ford Motor Co. for answers to my question about cranking my car and submit my question, the website sends me a message that my vin number is not valid. I have vefified that it is correct and I am not usinm ang o's or l's. Those letters are replaces with 0' and 1's per FMC instructions. I have tried it all ways possible and it still tells me my vin number is invalid. Why?
