1988 1989 1990 1991 1992 1993 1994 Chevy GMC Speedometer / Odometer Gear not working

[@tillwurfel7878]

Thank you for the clean, straight forward presentation. Good work.

[@jkemmerer1993]

Thanks for the video! I’m 17 and just bought my second OBS, an 88 5 speed 4x4. The odometer is broken so I’m going to give this a try. I should probably get an old cluster from the junkyard and familiarise myself with it before I tear into mine lol.

[@chrismorales9440]

Great to hear from the new generation of car people! I worked Pontiac, GMC, Buick dealer from 1991 - 2003. Then Honda from 2004 - 2016. I have worked on all makes and models. I have a degree in mechanical engineering. The opportunities in this field are endless. Never lose sight of why you do what you do. Never focus on the money. It will come easily when you’re having fun.

I got a cluster from the junk yard accidently broke the PRNDL cable is there anywhere I can purchase one?

[@joniportwood1974]

Watching you do this helped me. I replaced my speedometer gear too.

Great video,,very informative! Your truck is Super Clean

[@jimskenadore1791]

Thanks for the info. Now I know how to turn back the miles😜

[@christianrivera7948]

Thank you for step by step tutorial. Helped alot. 👍

[@lilphilosophy481]

I got the same year as you, rear differential is clicking, starts good runs good, but recently started turning off in reverse more often, now turns off either in reverse, drive while idle, or in park. Battery recharged, mechanic said everything else was fine, alternator, starter, but the negative terminal had burnt corrosion, driving it back it turned off at the stop light after a minute and a half.

[@chrismorales9440]

Is the steering column loose?

[@chrismorales9440]

I’ve seen the movement of the steering column move the ignition switch enough to turn it off. Tilt only

[@chrismorales9440]

Other intermittent engine killers: Ignition module Ignition timing pickup coil Fuel pump And last and probably less likely ecm and or PROM

[@rods.3245]

Disconnect the negative terminal when disconnecting a battery.

[@chrismorales9440]

And never set a battery on the concrete or it will drain.

[@rods.3245]

@@chrismorales9440That's a myth, but the ground removal first is for safety.

[@chrismorales9440]

Safety?

[@rods.3245]

@@chrismorales9440 Yes, if you remove the ground first, then the positive, you can't short through the tool by grounding it touching something metal.

[@chrismorales9440]

@@rods.3245 My opinion is: The potential to complete the circuit is exactly the same. But I know the arguments either way. In my experience it doesn’t matter. I say whichever is easier.

Great video, i have a 1990 Chevy 2500 and the speedometer does not work, ive replaced the speed sensor and the gauge cluster, still no speedo, any ideas what the problem may be ? Thanks in advance

[@chrismorales9440]

I would use a scanner to monitor the speed input. If the computer sees the speed then the problem is in the cluster. I think the wires for the speed sensor are bare and touching. I have cut the wires back several feet and spliced new wire. Make sure to twist them up like factory. I fixed these trucks at the dealer for many years. That is the most common problem.

[@Enderboss262]

if the MPH doesnt move is that the odometer gear? and is the gear supposed to move freely or is it supposed to be stiff took mine apart and its still.

[@chrismorales9440]

The speedometer is a different operation. You will have to find a repair facility for that, as far as I am knowing. We used to use Jimmy’s Radio back in the day. Who knows now if anybody repairs those. If I do i will do a video

[@z71_luis29]

Is this the fix to the loud gear my cluster has on my 93? The gear sound changes with the rpms, its loud behind the cluster

[@chrismorales9440]

Not sure about that. This gear fixes an odometer that doesn’t change when you drive it.

[@oclaude6389]

Hi, I have a problem with my Speedometer, sometimes he is workinf and sometimes not, so when I wrap at the cluster, he turn and than sometimes he stop again. The Gears are not broken . Thy

[@chrismorales9440]

Not sure. You would need a scanner to monitor the vehicle speed input. Then you can determine if it is the sensor or the cluster

[@gamalielrocha9896]

hello, what a gentleman, very good video, thanks for sharing, excuse me, could you help me recommend where to buy the indicators or replacements for the temperature on the same board that you have, I have a saw 89 pick up, best regards

LMC truck is a good one.

[@STEVEOMEMES]

Hello what was the TAPE for ? and thanks great video

[@chrismorales9440]

The tape was to hold the tumblers in the correct position. The plastic lock that held them in place broke into pieces because it was old and brittle.

[@STEVEOMEMES]

@@chrismorales9440 OK Chris THANKS.. so i wont need the tape if the plastic lock is OK ? My tuck has i think 400'000 mi on it runs like a top. the odomar went out at 100'000 mi and i have been told it was that little gear. DAMM i am gonna fix it ..some day. 😁

[@420BLUNTLEY]

What about 1995?

[@chrismorales9440]

They are different. Pretty sure.

[@420BLUNTLEY]

@@chrismorales9440 do you think I could just replace the instrument panel? H

[@chrismorales9440]

@@420BLUNTLEY yes. Replacing the cluster is usually the fix for most cluster problems. But you can fix them with help from yt

[@chrisluellen]

Very misleading putting speedometer in the title. This has nothing to do with the speedo.

[@chrismorales9440]

Calm down it’s a 7 minute video.

[@clinteast7476]

Tried it, Plastic broke that holds speedometer numbers..oh well i tried.Very brittle.
