So I took the cluster apart and did this. Worked as you said. I really appreciate it.

Glad to hear you got it fixed!! Nice work man
Chiming in with my experience here. I have a 2004 LX470 where the speedometer was working maybe 10% of the time. I'd start the car, and it would either work for the entire drive, or not at all.
I swapped the tach and speedo motors, and confirmed that the speedometer now worked 100% and tach 10%.
As others mentioned in this thread, I was unable to find new motors to replace it with.
What I did find, however, was a used cluster (part no. 83800-6D660 from a 2002 MY) for $300. I salvaged one of the motors with it and it works perfectly now!

Man i just want my pressure gauge to work consistently

I'll update my experience on here. I sent my new-to-me cluster back to Tanin for the second time for warranty work. They had it for a few days and sent it back to me. According to them, they replaced all the stepper motors with ones from a new supplier and that seems to have done the trick. I've had it back for a month and it's been perfect ever since.
I guess I had a batch of bad stepper motors or something. Whatever it was, I'm glad it's behind me now.

What happens with most of the stepper motors that "fail" is the bond between that small round magnet on the smallest gear fails, and the coils rotate the magnet but not the gear anymore. You can re-glue it and re-assemble it or replace it (i posted a video elsewhere in this thread of that process). I used a regular lc100 motor as it has the same internals to replace the internals of my lx470 gauge. The only difference is that lighting coil on the top for the needle.
Good morning! Quite the thread- I have read through everything and seen maybe a few issues like I am having but did not see any potential solutions. Driving on long distances, the Fuel, Voltage, Oil Pressure and Coolant temp gauges start to either go all the way up or all the way down, one side might be all the way up and one side all the way down or vice versa/mixed per side/etc. Sometimes an individual gauge will be close to correct but may be a little high when the others are going crazy. No jumping of the gauges, just like a flick of a switch they will change. Seems to reset after the vehicle sits for 15-20 minutes and may happen again during the trip or may not. First thought- Ground issue, but I am not sure. Anyone have this issue that can provide some advice? Photos attached- 1998 HDJ101, appears to have an LX gauge cluster.

My first inclination is the stepper motors. I was having super weird gauge issues too and thought there was no way the stepper motors could cause those problems, but after replacing mine (for the second time) the problems have gone away.
Good evening from Spain.
I don't think the stepper motors are failing, much less randomly and several at once. I also think that if it were the motors, the needles wouldn't stay up, but that's just my opinion.
I've had a lot of problems with my instrument cluster on a 2004 HDJ100 (facelift model). If you want my personal recommendation, I would ask a question on the chatGPT forum. You can't imagine the information they could give you.
I'm going to send you a conversation (in Spanish and also translated into English) with the diagnosis and instructions for repairing my cluster.
I hope they can fix it for you. There are good companies in the USA that repair these types of clusters.
Let us know how it goes...
Cheers!

Thank you, I will check this out!
Thanks!
I’m also having an issue with a recently refurbished cluster from Tanin. One of the gauges isn’t working correctly and they want to charge to “repair” something I just paid almost $1000 to fix. Standing by…..
Not great to hear.

How difficult was this? I'm half handy with an iron and I have zero tach. If it's just a stepper change, I should be able to manage it, as long as it's thru hole.

I had an electronics shop do mine because I didn't want any down time, so I bought a cluster replacement. Nothing went the way I thought it would and I had to send it back twice for warranty work.
If you have an LC vs an LX the parts are way easier to find and you can easily do it yourself.
Knowing what I know now, I'd just have done it myself the first time around.

Sorry that's happening. Pretty much the only nice thing I can say about them from my experience is that they didn't even question it regarding warranty. By the time I sent my cluster in a second time their 90 day warranty had expired but they honored it.
It'd be funny in a cruel way if you have the original cluster I had that I sent in for a core. Which gauge isn't working right?
That's terrible, I expected better from them.
Hi folks,
As shown in my post on page 13, my 2004 cluster had the different stepper motors (Lexus type). I can't afford to send my cluster to Tanin in the states, and in all honestly I'm not super confident in their work/support after reading a few previous posts on this thread regarding them.
Last week, I sent the cluster to a well regarded repairer in the UK, they have in general advised that stepper motor failure on them is very very rare in his experience, and that the issue actually relates to other problems (no further info shared). The issue after I attempted to replace the motors on mine last year (which were the wrong type) was that my calibration of the needles went badly and they've all been way off adding further confusion to the issue.
He has tested the cluster and has been unable to simulate any variance e.g. it doesn't vary in the speed/revs it shows on his test rig vs the speedo reading varying amounts over the actual speed when fitted to the car and driving. It's being returned to me this week with the needles re-calibrated, and I've been asked to record the issue next time it happens so I can provide him with more information on how it behaves so he can try and diagnose the issue better rather than going through the entire cluster without any clear cause.
I'm going to report back on this, as I'm very interested to see how this compares to the issues others have had, specifically with the clusters like mine fitted with the later LX470 type motor. Imagine the stepper motors on these later ones weren't actually the issue at all...
I'm still reserving judgement on the true cause/fix until I get an outcome either way, but it's an interesting twist!
