R32 GTR Headlight switch bug solved

[edthemanjp]

This worked for me

The situation: Passenger side headlight low beam doesn't work, tail lights and front marker lights don't work, and dash lights don't work.

After a couple days going through wiring testing the switch. After few blown fuses, busted knuckles, and cramped back looking up at a wiring harness under the dash. After replacing a lost switch spring with a cut down Zippo lighter flint spring (great replacement actually works better than original) I have half of the headlight issues figured out.

The reason the connector is burnt is due to arcing, arcing is caused by absence of contact. The switch doesn't make good contact with the wiring harness, it jumps around inside the contact, it needs to fit tighter. I tried grease that didn't work. Finally I did what I have done in the past I slightly bent the contacts a few degrees (about 15 degrees) then reattached and it fits really snug. The first time I twisted them too much and the switch wouldn't attach to the wiring harness so I had to readjust.

Test: Tail lights, front marker lights, and dash lights work. I have not tested to see if passenger light works attached to original harness as I'm happy with my current status and didn't want a let down, will test later.

Conclusion: This section of the wiring harness needs to be replaced along with a new switch, a better switch. The new wiring harness needs to remain snug while attached to the switch. The wiring harness may need to be taped to the bracket to eliminate bouncing during aggressive driving.

I can imagine the aching muscles from being under the dash. I usually lay the seat as far back as I can and sit in it upside down with my feet dangling off the head rest.

I used to do that but I weighed 170 then, I weight a little more and not so nimble. The other huge difference is the vision.

I feel your pain. I'm trying to lose weight now. I'm a chubby sumbich.

Take ten minutes and just remove the seat.

That ten minutes will save you a WHOLE lot of muscle pain. Used to do it with my Laurel and have done it twice with my R when I added my ETC system and re-wired my boost gauge.

This is true. This situation was over a few days and inside my garage no rush other than I just want to drive. The first go around my seat was out.

Just checked and the passanger side will not work through its harness, will have to leave it jumped off drivers side.

To note: The passanger side problem is in the wiring harness in the cabin between the key ignition and the switch harness. May be the switch, I know I need a new one and short piece of harness. Currently sourcing how to make the switch connector.
