Hi guys,

On the r33 climate control, when you turn the lights on, the display dims.

Thinking about it, this could be due to

1) circuit connected in series so display is experiencing a voltage drop because all the other lights are being powered

2) It deliberately dims, thus it must have a connection which tells it the lights are on

Does anybody know anything about this? Or how it works?

I want to keep it bright, even when the lights are on. If the reason is 2, then that should be an easy fix, if its 1, gonna be difficult

Thanks!

I have done this after I added a blue film to the display.

There is a wire that completes a circuit when the parkers are turned on.

I removed it from the connector block that plugs into the climate control unit.

The unit no longer dims when the lights are turned on.

ah fair enough

I need to do that to mine, I always thought it was brighter with the blue perspex. I guess it depends what tint you get

If you have a test light or multimeter handy should be easy to find the right wire. pull the plug out of the back of the climate control unit and test each wire with the light switch on and off.

If you dont have a multimeter then find one :P

Or maybe someone on here knows the answer/can test for you

Unplug climate control plug, put negative terminal of multimeter to chassis ground, probe the wires in the plug whlie turning the lights on and off

If you find a wire that has no power with lights off and power with lights on then that's your wire

Unplug climate control plug, put negative terminal of multimeter to chassis ground, probe the wires in the plug whlie turning the lights on and off

If you find a wire that has no power with lights off and power with lights on then that's your wire

thanks man

Just a note to anyone that tries this.

Taking the wire out does indeed stop it from dimming, it was a red wire with a blue stripe on mine.

However, this wire also lights up the climate control buttons when you switch the lights on. Taking it out means no lights for your buttons.

Id changed the climate control button lights to blue too so was a bit lame not having them. Rectified this by making my own wiring loom that comes from the wire that i pulled out, and goes directly to the lights for the buttons. It was easy because the lights themselves are easy to access.

So now when i turn the lights on, the buttons light up, and the display doesnt dim :D

    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
    • My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
    • There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
