I'll give you this, Telcoman: you are consistent. Definitely no waffling here. I stumbled across this on the NicoClub from three years ago. It's a reply to a tach light out.

The tach flickering thing has been happening to me this summer too, but yesterday a cold front came through and it was below 90 the whole day and it didn't happen since. Maybe when it's continuously 90-105* it's more prone to having issues?

Perhaps you might just replace the whole darn thing rather than d*cking around with the individual lights.

So I know this is an old thread, but my backlights have been failing for a couple of years... I have been searching everywhere for an answer to this question myself: How do I disassemble the G37 instrument cluster? So I decided to document the entire process myself and produce three videos on the removal, replacement of the backlight LEDs, and the re-installation of the console.

Take a look at my video over on my YouTube Channel:

Hey Dan it is hard to take anything serious from a grown *** man that wears jeans with holes in the knees!

All jokes aside great video!

Haha, yah, those would be my yard-work jeans for sure... Likely be shorts in a month or two.

I did notice that you have to go to the Youtube site directly to get to the LED Rework and Re-installation videos. Just FYI...

Dan, thanks so very much for the video links and production. They are extremely helpful.

You mentioned that you would replace the ballast resistors as well with around 25% more resistance, I presume they're the smd's near the driver IC's in your video. Any info on what package they are? I'm trying to put together an order of components prior to pulling apart my dashboard to minimize downtime. Did you happen to measure the resistance when you had that opened up?

BTW, my 2009 G37 Sedan has lost around four pairs of those led's now. The first to go was the fuel indicator, but now most of the tach is gone too. Very frustrating indeed.

Im in Texas and today it's HOT! I noticed that mine flickered a few times. I hope it's nothing serious. My outside temp was reading 105 when I noticed it...

Mine too....I live in S. Calif and issue started few years back, portions of tach and sped are not lit, not consistent each day, along with fuel and temp are completely off, not at same time, and not consistent.

Anyone know the led type for a 2010’s gauge cluster needles? I’m swapping the old style face and needles to mine and need to put red leds for the red needles, thanks

G3727

Sounds like this might work, please correct me if I’m wrong

Ended up ordering these for anyone who cares, lol

I have a 2009 G37S Journey as well. And just recently, at around 39K miles, one of my backlight LED's in the tach has also started to flicker randomly off. It doesn't do it very often, maybe on average a few times per minute. Sometimes it can go several minutes without flickering, sometimes several in a row. It is quick off then on, at around the 7K position. It also doesn't seem to correspond to hitting a bump or any kind of flexing. It can do it just sitting idle at a light. I am not sure, but occasionally, I think another will go off with it.

I expect it is going to get worse. I kinda wish that one light would stay blown, since the flicker is distracting. It is early in this issue, so I don't know if temperature will affect it. It would amount to a very expensive repair. I am too old and tired now to take on major projects like tearing apart and reassembling the dashboard, so this is more of a "me too" kinda post.

It is sad to see something like this happen in a supposedly higher-end car; especially one that is single-owner, very low mileage and garage-kept.
