Rewire the splice in the tire jack compartment, something went wrong at that point, maybe the wire feeding the van brake lights pulled loose, corroded or broke off from the splice joint.

THAT'S no joke, sad but true.

I have found using the hazard lights best way to make these tests for trailer wiring on most vehicles. That way you don't need to rely on clear communication from someone else, especially the untreated kind.

at least you got to know your wiring a little better, and have brand new splices! haha

Could be ruled out... just was thinking they dont work even with trailer unattached

Places like autozone will come out and take a look..?

But, yes, if trailer brake lights work...probably not switch...

could just be the brake light switch

this is a sample video, but I'm sure you could find one for your specific vehicle

did you happen to take it for a drive,? sometimes there is rust in the coupler and a drive around the block makes the ground contact, does the van lights work when the trailer is unplugged?? might just be a ground issue
