Nissan 26705-89942 Headlamp Unit

A failure of headlamp operation in all 240SX models and 1984 through 1988 200SX models requires examination of both the headlight motor fusible link and retract switch. An inspection of the retract control relay is required if the headlamps fail to retract. Begin by opening the headlamp and disconnecting the negative battery cable after unbolting and removing the finisher followed by the headlamp lid. Begin by taking out the bulb retaining ring along with unplugging and extracting the headlamp bulb from its assembly. Install the headlamp by following the removal steps backwards starting with holding the headlamp rubber cap with electrical connector tightly against the headlamp body surface. Follow the illustration to verify the lid joint alignment by modifying the headlamp lid screws while adjusting the manual knob on its motor. Verify that the lid does not contact the protector before evaluating the headlight adjustment. To operate the headlight manually disconnect the car battery negative terminal while turning off light switches then remove the headlight motor shaft cover during gradual counterclockwise motor shaft rotation to open and close the headlight features. The last step includes replacing the motor shaft cap while you reconnect the battery cable.

The positioning of headlights to the external visors should be well done to reduce comprising the sight of the oncoming vehicles and to enhance the vision on the road. Headlights feature two spring-loaded adjusting screws: One of the sockets is used for vertical mobilisation and the other for horizontal mobilisation and as for the auxiliary lights they have one screw for vertical mobilisation. To check the headlights, park it on a level ground, 25m away from a luminous white wall or any light colored wall, the tires are properly inflated the fuel tank is full and the weight of the driver sitting on the seat. First, bring the car in front of the wall and then switch on the car lights. To do this, use the masking tape and make a circle around the car then draw vertical lines passing through the middle of the car to make markings for each of the headlights. Horizontal tape line shall also be placed as the centerline of all headlights as well. First, position the low beam adjustment on the chassis, and set the point of high-intensity zone slightly below the horizontal axis and four inches to the right of the headlight vertical line, then tighten the screws. Finally, when using the high beams, place the region of high illumination four inches below the line of the horizontal respectively bearing in mind that low beams are safer. Auxiliary driving lights can be tilted up and down by means of this top screw.

For side marker lights, remove the lens with the retaining screws. Turn the bulb socket counterclockwise to release it, and pull the bulb straight out. To install, push the bulb straight in and turn the socket clockwise before securing the lens.
