Help 94 Caravan no headlights

I just inhereted a 94 caravan 3.3l the problem is when turning on the headlights I get nothing. The tail Lights come on without the headlights. I checked the bulbs and they are good. Any advice on how to troubleshoot?
Thanks,
Jason

Some vans have a Daytime Running Light module mounted in the engine compartment, on the passenger side firewall. If this unit fails the headlights won't turn on. The module is black and is about 3" x 3". Unplug it and the headlights should turn on. Good Luck.

I looked on passenger side of firewall and I have no Module there just the computer mounted on firewall any other sugestions?

Have you checked all fu8ses??

Is there power to the headlight sockets??

Check for power at head light switch.

Go to the online service manuals thread on top of page and look up the wiring diagram in the chasis electrical section, this will give you a idea where to start checking for power loss.

Possible faulty head lamp switch or relay.

Hope this helps.

Thank you, the wiring diagram is very helpfull, plan on printing it out and testing tomorrow.
Thanks again
