I'm hoping someone can shed some 'light' on this for me.
On one, not both, but one of my 2006 International School Buses is having the weirdest issues. I can only get the clearence light to come on when started. They will then flash and turn off. Here is a video showing you exactly what I mean

I replaced the switch, console, and have checked for grounds. Since it does have the 'flashing' going on, I'm pretty sure that it isn't a ground issues since it does flash, but I can't figure out what else it can be. I want to flash the Electronic Control System, but even the dealer doesn't know how to do that.
Any thoughts would be appreciated.
