Hey all.

I searched the forum and found plenty of references to worn switches, but I'm not sure this is my issue because when I unplugged the connector from the brake pedal switch the lights remain on, the only way to get them to switch off was to remove the fuse.

 

Can someone tell me if the lights will come on/remain on if the brake light switch is disconnected, like as some sort of safety thing?

 

Otherwise, any ideas where to start looking for the problem?

 

Cheers,

Mike

The brake switch pushes on a little rubber piece on the pedal itself; if that brakes or falls out, the lights stay on. Have a look at the clutch pedal in comparison and you'll see where the switch pushes

Whilst true....

Opening the circuit should kill the lights.

This suggests a short. Which suggests that you should break out the multimeter and start fault finding.

I don't have a car handy to swing around under, but definitely if the stop is missing/damaged or the switch is mis adjusted, the brake lights stay on rather than off. I've had to replace the rubber piece in 2 cars now for this reason (our old navara worked the same way)

Thanks GTSBoy and all. I figured that disconnecting the switch should kill the lights, but wanted to 100% sure before I start looking for obvious shorts. Trust this weird random crap to happen to me! At least I know what i'll be doing for some of the weekend. Think i'll start by pulling off the interior panels in the boot, looking for shorts and also removing the globes one at a time to see if its a dodgy globe. Probably then disconnect the boot lid stop light.

Managed to take a good look today, and found the remains of a 15mm round piece and a "mushroom" shaped piece of plastic. Really strange considering I had disconnected the plug from the switch and could see there was still one of these visible.

Turns out I should have looked harder. There are TWO switches, and the one I didn't see (its close to the steering wheel column) was missing that stopper. I haven't yet pulled that plug out, it's hard to get to, but i'd say thats the issue.

Why two switches though, redundancy? Some other function?

Could be for Cruise control or gear shifter if auto

It is an auto, but no cruise control. Was looking at some pics of someone's blog on the topic, and noticed that the second switch isn't installed in his, and that's a manual. On his car they put the switch in the hole furthest away, man I wish that was the one that broke on mine, if you reckon that ones hard to get at, when its closest to the steering column its a nightmare. Anyway, ordered the part from JustJap for about 1/3 what Nissan quoted and it'll be here in a couple of days. So that's a few hours of next weekend accounted for!

In the meantime, if you need to drive, the wiring plug is probably identical (r32 clutch and brake switch are), so just move the wiring across to the working switch

Just be careful, its an auto you might not be able to release it from park if you swap the wiring

That small mushroom stopper is $10-$15 from Nissan now. I tried using a round top bolt and securing with a nut instead, it worked but made a metal clunking noise every time the pedal hit stopper, so I paid up.

Nissan Berwick quoted me about $30. JustJap have them for around $10ea

Ended up ordering from JustJap, price was decent at around $10ea and shipping was $25. Seeing as I was going to pay that much for the shipping, I figured I should get my moneys worth and bought the Nismo smoked side indicators lol

Anyway, glad I ordered two because the one that was left also disintegrated too 🤦‍♂️

I wasn't looking forward to replacing them because just to see what was going on I had to twist my body in a way no human being is meant to, and I knew it would be worse trying to get hands up there, and might also need a bracket to be removed from the steering wheel. 

Pro Tip: Forget about removing brackets and having to shove hands up in to spaces they don't fit very well. Get a long flat blade screwdriver, like the longest one you find in sets (the ones that are so massive you always wonder WTF is that even used for) some blu-tac and a really decent bright light.

Start the engine, this will allow you to easily push the brake pedal down. Put a decent amount of blu-tac on the flat surface of your new rubber stopper and put that on the end of your flat blade screwdriver. Put the screwdriver and light in the footwell. If you are working on a concrete driveway, get one of those kneeling pads Bunnings sell in the gardening area, your knee's will thank you...

Open driver door as far as it'll go, kneel down, turn on your light and push the brake pedal down far enough to give enough clearance between the tab that holds the stopper and the brake switch(es).

Carefully pick up the screw driver (so the rubber stopper doesn't fall off) and, using the kind of hand eye coordination you normally reserve for a game of championship darts at the pub, push the screwdriver with the stopper on the end up inside the dash and past the inconveniently placed steering column bracket, aiming the mushroom shaped end for the hole in the brake pedal tab. 

Once you think you've got it there, push the screwdriver hard so that mushroom shaped end is completely through that hole. 

Remove the screwdriver and if the stopper isn't on the end, or sitting back on the floor of the footwell, slowly let the brake pedal return to its normal position (I pulled it forwarded a little and held it for 10 sec).

Push the pedal back down and slide a finger to where the switches are and pull away the blu-tac and if you can, give each stopper a reassuring push.

And you're done. Grab a <insert drink of your choice>, make your mate press the brake pedal while you marvel at the awesomeness of your work at the rear of the car. 

Oh, and if you're wondering, the side indicators are removed by sliding it towards the front of the car and when its moved as far forward as it will go, slip a fingernail under the edge that's closest to the door and pull it out towards you. No tool needed. Twist the globe holder to remove from the old indicator body. Replace the clear bulb with the orange bulb in the Nismo package, put bulb holder in new clear indicator and twist to lock in and push the indicator gently back in to the panel. Easy.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
