Lost My Running Lights except for Over windshield

[Avian]

while driving from the east coast through flagstaff and to pheonix, I noticed that my previously functioning running lights have now failed.

1999 National Tradewinds.

I replaced the two relays for running lighst and DRL and checked all the fuses in the forward left of drivers seat fuse/relay box.

I replace the AC/Delco pull switch for my running light and headlights...still nothing.

My head lights work, my blinkers work, my brake lights work, my back up lights work, but not my running lights.

Lost at this point. If it is a bad ground somewhere, then I dont know what to do at this point.

Also i am overheating up those long runs. The CAC is virtually impossible to clean from the bedroom. I guess I have to have the radiators pulled at some point.

My Dolphin did that last spring. For some reason I flipped off and back on the switch by the front door that kills all of the power to the coach.
Works good now.
Try it.

I hear what you are saying but the running lights etc are all powered off the chassis not the coach. But it may indicat that a wiring harness connection may have to be wiggled somewhere
