Nissan Truck Headlights

Nissan 1993 Truck. 4-cylinder, 5-speed standard transmission, w/air conditioning.
No low beam on driver's side. High beams good both sides. Can sometimes get driver's side low beam by rapidly moving low/high beam switch on steering column back and forth. Low beam will sometimes also return when driving. Anyone have any ideas?
Where is the headlight relay located on this vehicle? Have been told it is under the hood near battery on passenger's side, but I'm unable to identify. Help!

Thanks.
Do you

Hello !

Looks to me like the filament of the light is broken and with the vibration "makes" contact and lights.

Check that first!

With the headlights on "light tap" the headlight and see if flickers.

If not let me know and I ll get you the schematic.

(the problem its not the relay because both lights work at the same time with the same contact and the same fuse)

let me know and good luck!

I determined that I had a high resistance between the left headlight and the switch on the steering column. When I removed the connector from the headlight and measured the voltage on the low beam pin with a high impedance volt meter, I had the correct voltage, 12 VDC. However, when I connected small test lamp (low impedance) to that pin the voltage dropped to zero and the lamp would not light. As it appeared from the schematic, that the wire from the headlight connector went straight to the lighting switch on the steering column, I concluded that I probably had a corroded or poor connection on the steering column lighting switch. As I did not have a steering wheel puller to be able to see what was wrong with the steering column lighting switch, I jumpered a wire over from driver's side parking light to the headlight. I now have two functioning headlights, both high and low beam. The only downside to this "klunge" is that if I just want to use my parking lights, I'll have to put up with the driver's side headlight be on also. As I never drive with just my parking lights on, I can live with it. Thanks for every ones help.
