Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: How to Remove a Chevy GM Silverado Instrument Cluster

After pulling off the trim bezel by hand (they have no screws on most models, they just pop off by pulling firmly.) you'll find a few 1/4" screws holding in the instrument cluster. Remove them and you will then be able to angle the instrument cluster out. You may need to tilt the steering wheel down and move the shifter down to make room.

There will be one electrical plug in the back. You remove it by squeezing the tabs together and then pull back firmly while wiggling. It can be seized in place, pull and wiggle firmly and it will break loose.

Step 2: Removing the Clear Plastic Lens

Next up you'll need to remove the clear plastic lens. You'll need to use a small tool to pry out on the tabs while pulling up on the lens assembly to remove it. Work your way around one tab at a time, you can insert a pencil or similar item between the lens and the body to hold them apart while working your way around.

Step 3: Removing the Needles the Right Way

Ok now you'll need a few pieces of masking tape and a pen or marker. Rotate all the needles counter clockwise gently until the come to a stop, they should all stop at or just below the zero marks. Now make a pen mark on the tape just below the top of each needle. This will be important when you put it back together to maintain calibration so don't skip this step.

Step 4: Needle Removal

Now that you've made your calibration marks firmly rotate each needle further counter clockwise a few inches. You'll be rotating the needle around the motor's shaft so there will be some resistance especially at first. Don't worry, you won't break the needle if you keep your fingers near the base of the needle and away from the tip while you do this step.

Now pry upwards with a needle removal tool or even a fork, try to pry straight up and not at an angle, the needle will slide right off the motor shaft. Remove all the needles.

Step 5: Removing the Back Case and Circuit Board

Now pry outwards on the tabs of the back case to remove it, similar to how you removed the front lens.

Now you can simply lift out the circuit board. In the final pic you can see 7 white stepper motors you'll be replacing.

Step 6: Motor De-soldering and Tools You'll Need

Ok you're now ready to remove the old gm stepper motors and replace them with new ones.

Tools you'll need:

  1. Solder iron (not solder gun, they're too hot)
  2. Solder
  3. De-soldering bulb
  4. Pry tools
  5. GM stepper motors (one for each gauge, replace them all while you're in there!)

Use the de-soldering bulb and the solder iron to suck off the old solder on each of the four pins of each motor. Do not get it too hot for too long or you can damage the circuit board. Now you can pop the motors off the front of the board once all the old solder has been removed. If it's they're too difficult to remove you need to suck off more solder.

Step 7: Replacing the Old Stepper Motors With Your New Ones

Now you simply need to pop your new GM stepper motors where the old ones were, they will only install in one direction so you don't have to worry about mixing them up or getting it wrong. Make sure you get the correct part number when you buy your stepper motors (see link above for correct parts). Then you use the solder and iron to solder on a small amount of solder to each motor's pin. The solder should flow on smoothly, quickly and cool to a even shiny finish if done properly.

Place the circuit board back into the white center housing and snap on the black back housing. Now slide each needle back onto the shaft of each new motor being careful to slide it on smoothly and straight down not at an angle, to prevent bending the motor shafts. It doesn't matter what angle the needle is pointed at this step but, to make it easy slide them on pointing roughly at the 12:00 position.

Finally, rotate each needle counter clockwise until the tip of the needle points right to the mark on the masking tape that you made in a previous step. Remove tape and snap clear lens back on making sure to line up the odometer selector stalk. Clean the lens before installing if needed.

You're now ready to re-install the cluster and test our your gm instrument cluster repair job!

Step 8: Frequently Asked Questions

Q. What if I have light bulbs out too?

A. This is the perfect time to replace them, you can get the correct bulbs along with the stepper motors here: GM Instrument Cluster Lights they simply solder onto the board.

Q. What if I'd like blue LED lights, is that hard to do?

Q. Where can I buy the right parts to do this job?

A.You can get the correct fitting factory parts in a convenient DIY kit on Amazon here: GM Stepper Motors

A. Blue LEDs are very easy to install if you have the right ones made for 12V applications, you can get the right ones here: 12v Blue LED bulbs

Q. What if I have problems with the PRNDL shift indicator screen or the odometer screen?

A. Those problems are more advanced than my instructable covers, for options on having your screens re-done by a shop see here: PRNDL and odometer screen repair

Q. What if I replaced a motor and that gauge still doesn't work?

A. Probably what happened is the circuit board got too hot during the old solder removal causing damage to the board. See pic of a damaged board. This can still be fixed but you'll need a shop to do it.

Q. What if I'd like blue or white needles?

A. Like the lights this is the perfect chance to upgrade your cluster with colored needles, you can get them here: Blue needles or White needles

Q. What if my whole cluster intermittently goes out at the same time, all the gauges and lights go out except the check engine light?

A. If you're having this intermittent power failure you'll need a shop to repair the cluster, info here: Gauges randomly die at same time

Q. What if my odometer says ERROR?

A. Again that's something a shop would need to look into, see my links above.

Q. What if my needles are off a bit after I start up the vehicle?

A. In that case you'll simply need to unplug it, take the clear lens back off and rotate the needle counter clockwise until you get the needle to point right at the zero mark when it's plugged in and the key is ON. Make adjustments to the needle a little bit at a time (while unplugged) until you get it to point right at the zero mark. You may need to go 360 degrees counter clockwise all the way around stopping at the point you need to get it just right.

Question 1 year ago on Step 9

Are the speedo and tach steepers the same


Question 1 year ago on Introduction

Will this work on a 1998 chevy express or does it need different stepper motors. My guage is coolant temptature gauge is broken but the sensor isnt (verified with torque and obd bluetooth dongle).


Question 1 year ago on Step 5

My entire instrument pannel is flat lined, no lights, not even a ding for low gas. Will this solution work for me. 2003 GMC Yukon. Thanks!

Withh cluster plugged un but panels off, Zero needles for those u can, fill gass tank to full adjust needle to full mark, adg your dc gage in 12-13 volts, drive and check and make adj from there.

I put a new stepper motor on my GMC 2004 speedometer and it went to 40 and stuck then up to 80 and stuck. I can hear the motor working and some times the needle will move a little.

What should I do?

I have to comment a HUGE THANK YOU! I am a 47yr old mom of 5. I have done the occassional flat tire, checked oil and have almost always pumped my own gas, but other than that i know nothing about cars. A year ago we bought a used 2003 suburban and of course immediatly all dash instruments began to fail. I looked it up and of course it is very common but not under warrenty. After asking my husband to look into FOREVER I decided I would try. I found you! I have NEVER used a soldering iron or gun but i ordered your kit and got to work on your tutorial.....i now have dash gauges and it took me less then 3 hours. Thank you again so very much.

Last year my temperature gauge was getting stuck after I turned it off. When I would turn it back on it would start from that point. So if it got stuck in the middle it would assume that were it is, is at zero. My water pump went and from that point it hasn't acted up. Now its doing it again but now its also the gas gauge. Any thoughts?


3 years ago

My gauges seem like there's a short in a wire. They come on when I hit a pothole or sometimes if I hit the dashboard. Do you thinks it's possible that it could just be a poor connection from where the electricity connects to the instrument cluster?


3 years ago

Is the bezel connected/one piece with the clear plastic cover piece?


3 years ago

Maybe you can help? I change all 6 motors and it did not fix the issue.

Before i started none of the gages worked. I had power to the lights and checked fuses and they was all good. so i bought the motors and changed them. Which did not fix them! ugh Do you have any ideas?

I have the same problem that all the gauges are out.tachometer, speedometer, fuel level, battery, temperature we are working this morning and now nothing registers. I do have power for the blinkers and cruise control. what did you end up doing? any ideas on what is wrong no, I do not think it is every stepper motor out at samE time.

I fixed mine!! the issue is cold solder joints on the front of the circuit board. look for the black diodes that have a number 513 on them. and where the board looks like it has a yellow tinge in color. that is the area that you will need to really look at all the solder joints
here is my number if you need help 615 624 3847

Hi Rusell,

It sounds like you have a different problem, probably a problem with a component on the circuit board has failed or come disconnected/lost connection. This is fairly common on these GMs also, like the stepper motor problem is. If you can't find the problem we could take a look at it for you, I'm sure we could get it.

This is great! I borrowed my dad's truck while I was moving and the only gauges that work are the oil pressure and fuel level. I will definitely be repaying the favor with this helpful instructable.
