CJ7 headlight issue. PLEASE HELP!!
 
About a week ago with no warning the driver side headlight on my 1984 CJ7 decided to go out, not an unusual thing. Where the problem starts is that I replaced the light and the problem persisted, however, when you turn the high beams on, voila, both lights work just fine. The wiring (that's visible at least) seems A-ok and none of my electrically oriented friends can find an issue with it. Has anyone had an issue like this or have possibly heard of a fix for it??

Any help would be hugely appreciated.

Thanks everyone and HAPPY HOLIDAYS! :chilly:

In a factory configuration, low beam for both headlights are powered by the same wire (daisy chained together).

If the driver side is out but the passenger side works, the problem is either the light itself (swap headlights to test this), or the connector/contact is bad.

Bad contacts in the connector are pretty common. Sometimes just cleaning the corrosion off will help (fold up a piece of emery cloth small enough to fit in the slot). If not, they are pretty easy to replace.

Hope that helps.

I had this same problem with my 84 and I got pissed one day and punched my horn button lol and the light came back on I don't know why but it still works I think the connector on the light was bad

I also had it and thought connector. Jewelry file to contacts and worked for a while then went out again. Out of frustration took both buckets out and removed ground screws to inside of grill sanded and reconnected. No more problems and my yellow lights now look like HID. Get flashed often by oncoming drivers

Try the high beam switch! I found that my foot switch was bad due to a bad connection

A faulty dimmer switch will affect both headlights, not just one.

Good idea cleaning up the ground wires, I've gone the extra step and tied the grounds to the negative battery terminal. Food for thought as they say.

You are correct! Once I fixed the dimmer switch I found that the low beam bulb was burned out on one the headlights
