i have a 1992 240sx SE. and as of late ive run into a few problems.
1) _The headlights are up and wont go down (i've tried to disconnect the neg. battery cable, wind them down manually, and then try the switch again...they go up and stay up and wont go down (also they dont pop up when i turn on the headlights as they should, only when you press the popup button on the dash)

if anyone has some ideas i'm ready for a bit of help.

- thanks very much to anyone who decides to respond

I ressurected this to prove the usefulness of the search button...


regardless, I have been having the same problem, yet in reverse. The headlamps will come up all nice an quietly, with the headlight switch or the headlight motor switch (you know what i mean) and then their bein real ghey. When you switch the lights off, or hit the motor switch again I get no noise, no movement. Not even a reach around.

Both the H/L RET relays have been replaced and tested as well as the H/L Ret Down and H/L Ret Cont replays. H/L Motor (cant remember name 25A), Light control and all headlamp fuses are in tact. Please dont tell me I have to trace evey fookin wire, to every relay. I know the motor works, I powered both if the "motion prongs" Light one up, she spins 180* and stops, light the second one up she finishes the 360* motion. So it has to be in the wiring. Can I get a few good ideas of where to start, problems you may have had?

I opened the headlight motor switch (this is the switch right about 1990 240SX's cruise control On/Off). I jumped the connecters top two got nothing, no movement. The bottom two send the lights up. Lil help here guy, I have been at this since 11AM and its 5... im no electrician.


edit for the techs out there:

The relay under the air box (you should be familiar with the fastback for this, with power locks, windows and, ****) The H/L Ret. Down relay; Connector five has constant power. Connector between relay and h/l motor; connection 1 has power when h/l motor switch is turned on. But not when the h/l motor switch is turned off

While no other connection ^ has any power ever, whether or not the h/l motor switch is on or off....wtf?

Connection between replay and motor:

1 - 2 - x
3 - 4 - 5

will attach H/L Ret Down relay to repost below
