How do you replace the low beam headlight for the 2004 Nissan Quest?

Answer 1

Actually, the High and Low beam are separate bulbs. To replace the low beam, first you must disconnect the wiring harness from the bulb. To do this, depress the tab at the bottom of the connector and pull down on the connector. You may need a flashlight and a long flat screwdriver in order to press the tab at first, then you should be able to press down on the tab with your finger and pull down on the connector at the same time. (You may want to practice first on the High beam because it is easier to see and access) Once you have the harness connector released from the bulb, twist the bulb counterclockwise 1/4 turn to remove the bulb from the housing. When installing the replacement bulb, use care so as not to touch the glass with your fingers. (I recommend wearing vinyl or latex gloves) Press firmly toward the housing as you rotate the bulb 1/4 turn clockwise. When you reconnect the harness you should hear a soft click when the locking tab engages the new bulb.
