Question about 1990 Ford Econoline
Sounds like you have already done the obvious. on old fords they used to run the tail light wiring along the bottom of the floor pan, but on the outside. thus the wiring tended to go bad from corrosion and road damage. i drove an old bronco around for years with no rear lights until someone followed me home and told me.
jack it up a bit and follow the wiring harness from the switch to the rear of the van, will cost you nothing but time. if you see no damage, i would get an ohmeter and make sure there is continuity between the brake light switch wire and one of the two contacts in the socket. if not you have an open somewhere.
