None of my light work in the car and under the doors

If they all quit at once then there is no power getting to them, fuse or loose broken wire or connection.

Check the main fuses if all are ok you burned up a hot wire.

I think there was a headlight switch problem back then, it all go's through there.

check both fuse boxes,, One is under the dash inside the van, the other is under the hood,,

under the hood right near the battery, third fuse slot down from the top in the right column. BUT, it also powers the interior lights, wipers and turn signals, if those work = it's not your fuse. hope this helps direct you.

If none of the door switches trigger the interior light then check your interior light fuse on the fuse assembly located under the dash.
This could have failed usually a 10 A fuse.

You have a brake light switch under the brake pedal arm. When you apply brakes the arm presses a switch and turns them on. The switch may have went bad. Easy to replace. It's works like the push button in a refrig "open the door the lights come on" close it and the lights go off.

the fuse is in the passengers under dash fuse box which is behind the kick pannel ..under the glove box on the door side and you should see a little access door to get at the fuse box...hope this helps

if you can here relays when unlocking/locking check for power at door lock actuators inside doors, if you have power on lock/unlock and good earth from connector actuators are faulty.
if no power on test light when operating check output from central door lock module while operating, none coming out of module then it might need replacing.
check 30Amp power fuse for main relay under bonnet (which goes to pin 8 white/blue on module)and 10Amp gauge fuse in cab(pin 1 blue/red on module),pin 15 is also power when relay is on(red/blue) with test light, and module/ actuators.
check outputs from module pin 3 & 4
blue/red
blue/black
that go to door locks

check if the batteries in key remote are good.
if good
nedd to reset your key by putting in the ignition just turn the dash lights on ...dont start the car and once the ignition lights shows on the dash board just press unlock and lock once ot twice until it locks and unlocks while u in the car. try that it had worked for me before should do for urs.
