Three Questions... Regarding R33

I have three questions regarding a R33 Line.

- Firstly, i owned a NA r33 and whenever i turned the car of completly, then back on 20mins later, the climate control would come back on to the same settings as it had when i turned the car off.

(i.e. the fan was on two, the temp was on 22oC, the AC was on and it was going both feet and face. But when the car is turned off, for about 10mins or so, it would revert back to, not AC, 25oC and the fan is on one. It does it everytime.)

I have an idea that its not getting power when the car is off, the climate control is not getting direct power from the battery.

- Second question is the clock is giving the same symptons, it reverts back to 1:00, whenever the car is off for more than 20min as well as its is nearly impossible to view in the day time and only just viewable at night time. Has anyone had any simular experiences. (as per my last car, it worked fine day and night and never reverted back to 1:00.)

- Third thing is last night when driving home, my HICAS light came on and just stayed yellow/orange until when i turned the car off. It hasnt done it today but i am kinda wanting to know what happened.

If anyone has experienced any of these things, could i have your advice and/or what the outcome was.

Cheers,

Well... the clock should dim when you put headlights on... see if it goes dimmer.

It almost sounds like everything is wired up to accessories or something weird like that. I've never thought about whether the A/C has an EEPROM or whether it has a small amount of power when the car is off.

Perhaps check the wiring of the clock and/or AC with a multimeter when the car is off?

I'm sure someone on here will have an answer for you though!

Im not sure about the accessories, but i think your correct. I havnt taken the dash out to have a look, i just purchased the car from an SAU member 3 weeks ago. All i know is, no matter if the lights are on or off, or the dimmer is up or down, you still cant see it in the day, you can only just see it at night.

It would have a small amount of power, you would think, thats how it remembers.

I will check the wiring when i have some more time.

It is obvious that you have lost the circuit that provides battery backup to the A/C and the clock. Happy hunting.

The problem with the visibility of the clock is that they are back-lit - you have blown the globe (like a panel globe) that lights the clock.

Mitch its definately a clash with the assories and +12 perm line.

Seems like your AC and clock's +12 perm volts line is not connected or is wired incorrectly with the assories.... So when its off the +12volt goes away...

I wired my HU the wrong way around and when I turn off the car the AC and clock would reset. Then I rewired it and it worked fine.

ALso check fuses if they have somehow blown? but then again u wouldnt get any power if they were.

This is all well and good and i think you are all on the money, today is going to be spent messing around with it. But one weird thing about the way the precious owner wired the headunit is, the 12V +, comes directly from the battery... i think that qualifys for "what the" because there is a power in the dash to be used. (well there was in my NA R33.)

UPDATE:

i pulled the dash out today, None of the wires in the plug going to the clock or the Climate control have been cut or pulled out.

I am totally stumped. I left the clock out and now im trying to find someone whos r33 i can use to put my clock in and see if it does the same thing. Anyone in the western sydney/st clair/erskine park area wanna give me a hand?

Cheers,

Yeah i got an aftermarket nismo steering wheel.

It has a boss, but after reading another thread, when you travell on the highway and dont turn the steering wheel much the yellow/orange light comes on, i noticed that work the other night when i was on a straight for ages and it came on.

Thanks for the advice.

      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.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.

      My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
