HEADLIGHTS

1997 Infiniti J30

Electrical problem
1997 Infiniti J30 6 cyl Two Wheel Drive Automatic 135, 00 miles

I notice that my right side headlights was inop, high beam low beam not working. I checked the lamp by removing the good lamp from the left side and placed it in the right side. Problem followed. I then checked power to the right side/no-light side; I did not have power to the light plug. While playing with the lights my battery drained, not normal for a short time with the lights on. Anyway, I jumped the car and the right side lights started working. However, for a short time. I cleaned the lamp plug and lamp worked for a short time. Also I do not have any high bean to the bad side, normally if the light is bad you will still have a high beam it's two different lamps, right? Anyway, I cleaned the ground on the car battery and checked voltage with car off and car running everything checked out. Relay?

Hi jazdre,

Thank you for the donation.

Is your vehicle equipped with Daytime Running Lights?

Here is a diagram of the healight circuits for your understanding. Since jump starting the vehicle had the headlight working briefly, the most likely cause would be the DRL control unit. Check the control unit wire harness connector and note if there are any contaminations.

No, the DRL Unit is not the same as headlight relays. It is a small control box with 14 terminals.

Sorry the diagrams did not show up well. I am only able to print the diagrams to mdi files and can send it to you via email if you have the program to open it.
