O6 U320
My guru buddy is working on a a 06 U320 production number 6304 and asked me if anyone knows what purpose a small clear plastic line might have he found in the overhead front cabinet above the drivers and passengers cabinet?
Hooked up to nothing. Was behind a removed covering panel. Long enough to reach the passenger side.
I think the coach has overhead wipers. He wondered if it was windshield washing. Did not want to spray inside the coach to see.
Any ideas?
