Nissan Repair: pasenger head light wont work, daytime running lights, nissan cars

Question
QUESTION: 1987 nizzan 300zx the light on the dash came on intermittently indicating light problems I checked and the passenger headlight was not working. I changed the bulb and know it does not work at all and know my fog lights don't work. The car is a mint condition USA car with 100,000 miles. I changed the bulb and fuse and it will still not work. The plug for the bulb looks brand new no corrosion. I did clean the plug with contact cleaner and also changed bulbs and fuses with drivers side and still no passenger light. Could I have a faulty relay or controler.

ANSWER: Brian,

The headlights are fused independently as a safety precaution.  My bet is the headlight switch is defective and it is in need of replacement.  rockauto.com, courtesyparts.com autopartswarehouse.com or the like and you should be able to get a deal on a headlight switch.  There are individual contacts in the switch and one has failed.  You did pretty good since it is a 1987.  20 years is about normal for failure on older Nissan cars.  The new ones fail in about ten...

QUESTION: I purchased a new light switch from nissan and installed it. I still have the same problem. I also do not think the daytime running lights or the fog lights are working. The park lights do work.

Answer
Brian,

The ground to the headlight is good?  The car has not been in an accident on that side?  The headlight fuse for that side is good?  1987 USA car should not have daytime running lights?  The headlights are on a separate circuit from the parking lights.  Tear the old headlight switch down and you will see the difference.
