Got a 2003 LC. Speedometer stopped working. Replaced the vehicle/transmission sensor...didnt work. Replaced the ABS speed sensor....didnt work. Any other ideas?
Speedometer stopped working

Just an idea, if you have access to techstream or scanguage - you could see if it's actually reading the speed. This would help determine if this is a display issue.
Perhaps re-seat the instrument cluster?

I'm not entirely sure this will be helpful, but...do your reverse lights work? They share a fuse with the speedo. If you've done any work around that, or maybe have an aftermarket trailer harness—whatever would cause that fuse to blow might be worth the 5 minutes to check it out.
The particular fuse is behind the PS kick panel, I believe.

After you've confirmed the fuses and such are good, @planomateo probably has the answer. I had the same problem, did the same 'repair' by swapping the VSS. Nothing. I needed to partially remove and securely re-connect the cluster. Worked great after that.

Just checked. Reverse lights are working.

Looks like thats what i have to do. Is getting to the connector for the cluster difficult?
Probably need to replace the stepper motor. The other gauges likely aren’t far behind. I wrote a thread on the replacement. Search “stepper motors” and I bet you’ll find it.

Any feedback is much appreciated!!
OK, just happened: speedo stopped working during a drive, all other gauges working.
Using OBD2 w. torque, gps speed matches vehicle's ECU speed output. That tells me that all the downstream stuff (sensors, etc.) are working.
Before I mess with the cluster (cluster connector compression screws), is there anything else I should check?
Thanks in advance!

Bump for top secret insights on this......
This just recently solved my Speedo not working on cold mornings. The other conditions I had were no Cruise Control.
I was hoping to avoid this "cluster", but will bite the bullet. Hopefully I won't break anything in this operation.
Bonus: gives me a chance to replace steering wheel extension motor.
Its pretty simple, disconnect battery, pull the trim pieces on the side of the steering wheel, pull airbag (disconnect), remove steering wheel (be sure and mark orientation), then remove the bottom trim piece (pull straight out or pry with trim tool), disconnect dimmer switch dial. Then remove 2 trim screws at the top. then you will have 2 black trim screws at the bottom corners of the cluster and the 2 large screws to disconnect the cluster wiring harness itself. This is a good time to replace any burned out bulbs. Prior to replacing the cluster make sure the harnesses are attached to the plastic. When replacing the cluster the large screws will tighten until they spin freely (they will click), they do not stop spinning. Here is a shot of the harnesses.
back of the cluster
That is way too deep for my pay scale. I just know I would be breaking other things.
There is a video reference in this forum that a) does not require steering wheel removal, b) cluster connector screw tightening while moving (too make sure that is cause).
If that fails, the stepper motor is next. 'Course coudl live with the smart phone/OBD work around.
Issue is you can’t pull the cluster out without removing steering wheel. Here’s a hint though:
There are two nickel-cad looking screws: one on the bottom left and one on the bottom right. These are what secure the cluster into the harness. On my 2000 lx, I could press on the left screw with a phillips screwdriver and get gauges working on right side. By pressing on the right screw I got gauges to work on the left side.
This told me my cluster wasn’t seated correctly. If you have the same issue, you may need to pull the cluster to put something behind the connecting harness so you seat.
The screws mentioned are easily accessed by popping off the trim piece that contains the dimmer switch.
Hope this helps
Everything helps this wannabe wrencher.

LED instrument panel/gauge cluster
After viewing Loud's LED thread, I had the urge to update most of the the bulbs behind my gauges to LEDs. No more dull lookin' gauges at night. Bulbs replaced were the speedometer, tach, fuel, water, oil, and battery. Gear shift indicators, turn signals, and brights were updated as well...

It could work. For my LX, wheel didn’t drop enough out of the way.This just came across showing stearing wheel remaining in place:

Pushing on the screws only requires lifting one trim piece and that can be done without tools.
