Would that make a difference? It’s not one bulb either, it’s all 8 marker lights and the taillights. All or none work or don’t depending on how long I drive.Coach marker/running lights issueThis one has me stumped. 97 class c Fleetwood jamboree. Ford E super duty van chassis and Fleetwood coach. When I turn the headlights on the chassis lights work, headlights, van front end running and turn signals all work but none of the marker lights or running lights work on the coach until I drive for about 5 minutes. Once they start working everything works perfect until I turn off the RV for a while. Bumps and rattles do not cause any flickering, so if it’s a short it’s the strangest short I’ve ever seen. Any thoughts?
