No tailights dashlights - no fuses blown?

Check your Tailight fuse to see if it's blown, if so then start checking for a bad bulb(shorted element) in tailight circuit boards . and also don't forget to check grounds as well, there should be one at rear frame by left (drivers Side) tailight connection/trailer harness connection. hope this helps. do your Brake lights Work ?

GOOD ADVISE--I ALSO LEARNED THAT THERE MAY BE FUSES IN UNDER THE HOOD ALSO. FOUND OUT TODAY THAT IF THE DOME LIGHT DON'T WORK THEN IT'S FUSE COULD BE BLOWN AND HINDER THE CIRCUIT TOO. I'M NOT GOOD ON VOLTAGE READING , BUT DO HAVE A TEST LIGHT. IF NO FIRE AT THE COMMON TAIL LIGT-DASH LIGHT FUSE , THEN THAT MIGHT NARROW IT DOWN. I HAD THE SAME TROUBLE IN MY 1990 FORD XLT LARIAT AND WAS BLOWING THE TAILLIGHT FUSE. IT WAS A SHORT IN THE EXTERNAL TRAILER KIT HARNESS WHICH CAUSED FUSES TO BLOW REGUARLY. WHERE IS RELAY FOR TAILIGHTS AND OTHER FUSES UNDER THE HOOD??

Okay, these are hard to find. I assume you have no problem when you do not have the Tailights on? This would mean problem could run all the way to rear taillights.

But if the problem is not related to putting power through the wires to the taillights it is under the dash area. You would have a short from the power supply to the lightswitch. You have a Relay for the lights in the Powerbox.

Go to Autozone.com Website and register your vehicle for a free wiring diagram and Powerbox layout.

You can then see for yourself about how the dashlights are grouped with the taillights. You could have a bad Relay.

Look at how the taillights get their power and this will show you a color/coded path from the front to rear of your car. As I said earlier, it is important to know if the lights only short when they are turned on by the headlight switch.

If they short out all the time, regardless of the headlight switch being on or off, then the short is more towards the front, between the dash and Relay or the Relay itself.

Use the built-in cutoff points as a way of eliminating the shorted part. The headlight switch is a cutoff point. Power rearward is halted with the except of the Brakelights. If the Brakelights work fine, the bulb sockets are probably grounded properly.

If the fuse pops with the headlamps off, the power is not going rearward and you are okay.

This problem sounds like there is a short, first locate the fuses and replace them if they are blown, most likely they will be.

You will need to do some checking, we know the short is in the tail light dash light area which is considered the park lights,
This may be due to a bad wire or switch, if you have a trailer hitch on this van i would start there,

Locate the connector for the trailer lights, on the rear of the van , follow the wiring and look for bad wiring or wiring rubbing through near metal area,
A good test would be to install new fuses and turn lights on as you have someone keep an eye on them to see when they go out, turn van on and lights also, see if fuse pops , if it does then locate the wiring for rear lights at rear of the van behind rear bumper area you will see a connector that connects the wiring for rear lights, remove the connector , this will stop all power to rear lights and will be a test to see if the short is in the rear tail lights, with connector removed install new fuses and turn lights on, if fuse does not blow then now we know short is in rear from that point back, check wiring and sockets very closely, make sure correct bulbs are installed.

this is where i would start, let me know the results of this test i we will go from there, good day

i assume you forgot to mention the tailights are working and the license bulb is good.the license light works when the tailights are on.so you need to make sure the socket is being powered and it has a good ground if not then you will have to check the wire for the license to see where the power is lost or provide a good ground.it could also be a bad socket.

Sounds as if you may have a short did you check the bulbs? I would check the bulbs and make sure they are good. when you lift the rear hatch lid search around the wires and see if you have a exposed wire or perhaps a loose wire connection. Allot of times wires in a vehicle that year start getting frayed and worn from putting different items in the rear of the vehicle.

the connector that holds the bulb is faulty or an open wire check for wires being exposed by connection. also check the fuse pannel for a blown tailight fuse or brake lights fuse.

it sounds like a short in the park lights.you will have to start by disconnecting headlight switch then install fuse,then check all park light bulbs and there sockets, its gonna be a bad switch or socket, enless theres a wire touching ground ,but start with the switch and checking all sockets. hope this helps.

..check the fuse...and checked also the grounding..also..try checking the switch to make it turn on..sometimes..it may loose contact...
..if things does'nt work out..better a qualified auto-electrician check it...hope this help a little

There is a seprate fuse for the running lights alone. Check the fuse and replace if blown.
