Welcome back:
It could be as simple as a fuse, however, it could be more involved. Check the fuse I suggested and all fuses in the box.
What worries me is this. If he says he thinks it is a simple fuse, why did he not already replace it. It would make the vehicle easier to sell and worth more.
Always remember the old saying, "Buyer Beware". Would he allow you to have it checked by a mechanic?
Please feel free to let me know if you have any other questions or concerns.
Take care,
Joe
