hey all, I thought iI would pop this up here for all you to ponder. its got me stumped.

I have a 32 gtst, which occasionally the left side headlight wont work. OK sounds like a loose wire or bad earth.

Except when you turn the headlights on and off again it works the second time.

only thing i can think of is maby dirty contacts in the switch?

it has also done it when you turn the high beam off, not very often but it has done it.

any ideas of what to look at and what to try?

cheers jamie :banana:

I had the same problem, exept my right headlight didnt work at all. What i did was meter the voltage without the globe connected. both headlights metered the same but when a globe was plugged in it wouldnt work. The way i fixed it was re-wired both headlights with relays on it. Its about a hour worth of work and will cost about $20 for the relays but it fixed it and havent had a problem since. I have read of people pulling the switch apart and cleaning and bending the connections on the switch,i just cbf pulling the switch apart.

my 2c anyways.

Nissans use a 4 circuit headlamp switch (high low right left)therefore 4 contacts are used.More than likely you will have a dirty connection on one ,easy fix fine wet and dry paper and retension contact

Yep, odds on it's actual headlight switch in the dash. Nissan decided to have the lights draw all the current through this switch, instead of run a relay. So over time the plastic contact lugs melt.

When my car did this, I just got a 2nd hand switch which fixed it. Plan to wire up the relays when i've got some spare time.

Nissan uses multiple ground paths for lights , look near the radiator /headlight you should see a ring terminal on a bolt. on each side, can be rusted or loose from years of abuse.

also the switches fail often, similar issues on my R31 , pulled the switch apart (frosted plastic bit on the back of the switch )and the contacts needed small tweak/filing to contact again(poor man fix)

or switch out the headlight switch fixes it 90% of the time if the grounds , relays are good

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
