No idea why this is happening. All outside lights appear to work except the rear exterior courtesy light on the back part of the cab. Interior courtesy lights don't come on and radio keeps blowing its fuse. I don't know if these are related, but since it happened at the same time, I assume they are. Any help on how to troubleshoot this, or where to start looking would be helpful.

Thank you.
