Low Beams dead, Hi Beam Fine?

Geez man learn to troubleshoot and stop wasting time parts and money "throwing them" at a problem. Buy yourself a test lamp, a cheap multimeter, and get/ make some alligator clip jumper leads, and go over to MyMopar and download yourself a free service manual

WHY AM I SUCH AN *****LE about this? Simple. In my younger days I had to BUY a service manual if I wanted one. There WERE NO easily obtainable cheap RUGGED multimeters. They were analog meters, and if you wanted a small cheap one you had to order them from an electronics supply house. This was before RadioSh*t, and hardware and parts stores carried and sold them.

SIMPLE

Get a test lamp

Access dimmer switch. Turn on headlights and look at the cluster, and cycle dimmer so that high beams are OFF. Now probe the dimmer switch. There are three terminals, and with light switch "on" there should be power on 2 of them. One is power TO the switch from the headlight switch. One is power TO the high beams, and the 3rd is power TO the low beams

If you have power there, look up in the diagram/ manual, and find the low beam power feeding through the bulkhead connector. Don't have it? Simple. It's right there in the bulkhead connector

Try wiggling the connector, watch the lights. They come on? Flash or flicker? You have found it.
