R32 GTR

So after searching around for awhile, I cannot find any other threads that cover the issue I'm having

(At least none that people actually posted fixes in anyway)

So basically, As long as I can remember, my right low beam headlight has always been dicky, turning on and off for no obvious reason. Not that big of a deal, good ol' Lefty will keep me goin'.

My dial switch had failed long ago with the previous owner, who had simply attached the low beams switch to a toggle. This had been working fine for nearly two years until one day, BOTH low beams stopped working.

I still retain parkers (Separate circuit I know) and strangely High Beams. This suggests to me that it could be one of the relays is not making the connection for the low beams. Really want to solve this issue as I don't want to drive around using my high beams for the rest of my days.

I've tested continuity throughout the entire system and seem to have 1/1 connection. which just confuses me more!

Please MTV SAU Fix My Ride!

But seriously, for the good of me and the retinas of other road users, I need to work this out.

Any info people can offer would be really appreciated.

A friend of mine used to have a 32 and we sspent a while one night with an issue with his lights. Think it was similar. Only 1 low beam or both low beams were off but high beams worked. Ended up being something in the indicator stalk (high beam part of it of course)

From what I know they go bad with age because of the way the are designed

Same issue on my 32 GTR. I bought 2 x 2nd hand replacement switches and both were similarily farked.

I was also told it could be stalk related but in my case it wasnt.

If it's already rewired the low beam to another switch I'd take a second look at wiring, fuse or the brown resistor/relay in the main fuse box in the engine bay.

The only thing that fixed it for me was replacing the dial switch on the dash with a new one from RHD.

I read about a mod too keep the low on when switching to high.

Basically join the high and low wires near the plug behind the dash.

Ps my 32 lights are a nightmare, thinking about making a whole new circuit just for them. i just cant work out wtf is going on with the hi-lo wiring.

Sounds like the high/low dipper switch. They give trouble with age and can be repaired if you're keen.

But unless you address the woeful wiring design it will fail again.

These cars switch full amperage at the high/low dipper switch, it's not switched by relays.

When guys fit 100w bulbs or even worse, mod the dip switch to switch low on with high there's not much hope.

To fix the car you need to modify the factory wiring and install relays to do the switching. Then your dip switch will only be switching the trigger load, which is tiny.

Also fit a diode to trigger low to stay on with high.

You'll see a vast improvement in the lights as voltage drop is eliminated.

Fit 4500K max HID's to low beam if you have the projector style and with low + high the highway illumination is excellent.

Retain conventional halogen bulbs for high so they switch on quickly unlike the HID's.

Here's my fuse box showing the extra relays and diode.

Job isn't difficult, probably half a day, you need to source factory relays so it all looks the part.

Thanks Jiffo!! Rare to actually get a detailed response to these kinds of threads so thanks a lot for your info!

I bit the bullet a few days ago and basically just ran new wiring from a switch inside to a separate relay and new wiring for the headlights. I'll be doing this again shortly for the highbeams, just to save myself any hassle in the future.

But again, thanks for the info! Really glad someone still cares about the "HELP ME!!" threads :D

    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
    • 1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
