Cold here in Port Pirie, but cold and dark is worse. LED roof lights have gone inside on my 2015 Jayco Swift van and I've checked the fuses. Online I can see that some Jayco fans have a kill switch on pop ups that sometimes sticks and this could be the problem but I can't see any on my van. Any electrical wizards out there with a suggestion??
The kill switch is usually on the rooftop edge , on the outside of the canvas,it makes contact with the edge of the van when it is lowered,it is near a corner post.
It turns off the interior light to stop them burning a hole in the canvas,when the bed end is push in and the roof is lowered and the light switch is left on.
Which happened to us years ago when we had a Jayco Dove,them days the lights were incandescent and had a fair bit of heat.
Hopefully it just a sticky switch,
