Check for 12v going to headlights, if headlight plugs are getting power then both headlights are burned out.
Check the headlight switch for power coming into it. If its getting voltage in, and headlights not working, then its the switch.
If switch isnt getting power, check for a blown fuse in the fusebox.

Trouble shoot heater fan on a 1996 Plymouth Voyager Van

Check for 12 volt power to resistor under dash on passenger side. Follow wires from under glove box (from blower motor) to resistor, which will be where wires are connected on duct work. You should be able to test for 12 volt DC power there.

Running light problem on chevy express 3500 box van

Vehicle electric trouble shooting is the worst. Some of the problems you described the bulbs may have multiple filiments with only some burned out. It may sound silly but change the bulbs. Get a couple of new bulbs and try them in the different spots. Time, road vibrations and spring pressure causes the contacts on the bulbs to wear until they get a poor connection then you get a little arcing that build up a residue and a bulb that test good doesn't work.
Your on the right track with the ground wire. Try a test lamp with a good gound connection and test the different sockets, if your test light works but your bulb doesn't you have a ground fault. If neither work check the switch and fuse before you start tracing the wiring. These are just general trouble shooting tips It's very hard to trouble shoot electrical problems sight unseen.

I have a 1994 chevolet conversion van g20 series. the blinkers stay on in the van but do not work on the outside and when the head lights are on do not work at all anyone have any clue as to why?

you have a burnt bulb, put your 4 wayson(safty flashers)walk around the van, if your signal lights are not flashing get a bulb for it .or even autozones will help find them and help you put them in if you never done this before
