Ok,,,,,lets dial it in some more,,,,,I see no left brake/stop light,,,,,you say no right side,,,,,you got circuits back there ,,,,,tail--stop/turn---ground,,,,,,,, the tail lights wire,,,,,probably brown, comes all the way from the headlight switch to both rear lights,,,,,,the left turn/brake wire,,,,yellow,,,,comes from the connector under the blower switch,,,,,,,the right turn/brake wire,,,,,,green,,,,comes from that connector too,,,,,,,,the point is,,,,,,check your voltage there,,,,,its hard to tell in back what is on,,,,,,is it the dull tail light or a dull stop light because it has a bad ground,,,,,they look the same,,,,,but like I said,,,,the turn signal switch calls the shots,,,,,so do your tests at the steering column,,,,,lets do that left side ,,,,,find that yellow wire that comes out of the turn signal switch,,,,,see if it lights up when you hit the brakes,,,,see if it blinks when you put the left signal on,,,,,take a jumper wire from the fuse box and power up that wire,,,,,,see if the left rear brake/turn light comes on back there,,,,,,,the idea is,,,,see if you got at signal out of the turn signal and THEN,,,,,,see if it gets back to the light in back of the van AND,,,,see if it lights the bulb correctly,,,,you just got to isolate the problems,,,,one at a time,,,,and what year is this van??? As for the socket,,,thats probably pretty common,,,,,look close at it,,,,,,you need to trace how the base of the bulb gets connected to ground,,,,and its probably pretty flimsy,,,,,like some tabs that rub each other and are bent or broken,,,,,,but start at the column,,,,see that you actually got the 2 brake/turn voltage on each of those 2 wires going to the back of the van ,,,then figure out why the lights are not getting those voltages......
