My driver's side headlight is dim. I suspect it probably is a bad ground or poor connection somewhere. Any suggestions about where to start looking? Any chance it's the bulb? I have H-4's and will switch out the bulbs to see if the problem stays on the same side. I suspect it will.
Thanks |

"Check the grounds... Clean the grounds...." The headlight grounds are located by the headlight motors. Pull the nuts off and clean both the ground point and the loop connector. Inspect the wires at the loop connector for any fraying or breakage. |

Check the voltage at the headlight with a DMM. With engine running it should be over 12.8 volts. The usual culprit is a bad ground. If you end up with a lower voltage reading, try stretching a meter lead back to battery ground(with a jumper wire) and take the other lead to the headlight harness and see if the reading is higher. This will verify the condition of your headlight ground.

My car had an odd problem where one headlight would sometimes be dimmer than the other one. Not all the time, mind you. When it was doing that, it would take longer to turn on than the other one.
Turns out the ground for the bad light was intermittent, and it was feeding back through the other light to get to ground... I replaced the ground wire, and all was happy again. --DD |
