Major Power Windows Problem

I've read dozens of threads on here, 350 tech, g35 driver and cant seem to find anyone with the same problem I'm having.

Car is an 03 v35 coupe.

Yesterday my windows were all fine doing everything as they should. My door locks were all ok however the interior switch would lock but not unlock the doors (since I've had it).

I went to get some dinner and the auto "anti pinch" on the drivers side hesitated while the passenger side had dropped but now the door was closed wouldn't raise. I looked at the switch and noticed the illumination wasn't functioning and tried the switches which of course gave me nothing. Then the window switches flickers a quick tap (which I think did nothing) and the dropped 10mm as they should. Open and closed both windows fine, closed the doors and all working as they should.

I drove home (3-4 mins) and now the illumination is out, the main control switch doesn't control either window the passenger window switch operated the window down but not up (even with the lock switch activated) the pinch on both windows wasn't functioning, the door lock illumination is on but the switch does nothing, no tapping or playing about with the door helps.

The windows have worked fine up until this point. I've had no problems other than a lazy passenger side door lock which only plays up on a warm day.

I cant see that it would die instantly in this manor from a dirty motor so I'm thinking its either a BCM or main control switch. I cant drive the car anywhere because I cant get the windows up, nissan cant look at it for a week and the workshop manual I have is for the yank cars and the BCM is different so I cant test the units.

Nissan have quoted $400 for a BCM but it seems from reading I'll need to tune this as well. Is there anyone who can help me diagnose the issue and test the BCM and main switch failing that is there a good auto electrician who is able to sort these cars out quickly?

Any help would be appreciated.

Thanks, I've just tried this but unfortunately it hasn't helped. While on the topic of battery, it is a fairly new 610cc.

I'm thinking its most likely the switch unit as everything else seems to be working fine; its just the windows. I've booked it into a local auto sparky. I find it funny the number of adds in the yellow pages quoting "BCM repair".

I'd still love to get anymore advice that could help me sort this out ASAP.

Thanks.

Just spoken to the auto electrician who's told me that his scan tool is able to access the windows but its coming up with a communication error. Unfortunately without a wiring diagram he is unable to to continue testing. I've also called Nissan FTG (local GTR dealer/biggest nissan dealership) but they said they don't have the wiring diagrams either.

I have the hacked workshop manual for the G35 from "heatsink ninja" would this be the same wiring digram or not? Does anyone have the wiring diagrams that I need? This problem is become more urgent.

Thanks for any help.

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

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

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
