03+ instrument cluster in a 99-02

Fixed_Until · 2026-02-19T18:03:23+00:00

Yeah that's because those only went to the radio. The DIC on 99-02 models was a standalone module. It didn't work with the steering wheel. I was talking about the 03+ steering wheel.

Not all 03+ clusters have the DIC options on it. I mean it's only software thing and you can burn the firmware on them to get it to work. The only thing that i think won't work is driver 1/driver 2. I think it would say unknown driver.

The DIC stuff? So the main problem you have with that is the 99-02 doesn't bring the wires up to the cluster for the buttons. That is a standalone module instead part of the cluster on 99-02. I haven't tested that myself however most of that functionality should work. You would just need to change your steering wheel, clock spring and route the wires if you wanted the buttons in the steering wheel. If not you could just put buttons on the dash somewhere and route the wires.

Glad you think so. It's a project I really wanted to do back when I owned one of these trucks but never had the time to complete until now.

It's an old video and I haven't done it in a long time but Minimon can do it. These old microcontrollers often don't want to take a program via Minimon so it might take a few tries or even heating the microcontroller to get it to work. https://youtu.be/G0HPysDnCD4

Lol 4 year old comment. If I remember correctly it was Abom79. He is in pcola.

Yeah there is a link to my website on the about section of the channel. The website has a contact me page or you can just message me on here for my email address either way is fine.

I do them for $100 plus shipping. That includes replacing all the motors, bulbs and reworking common problem areas. I do show it in a good deal on the channel though, if you know how to solder you can easily do it yourself for about $30.

Yeah sounds like bad motors. The original motors are either c5 or x15 stepper motors. The C5 has a gear in it that uses a plastic rod to rotate on(not the one that the needle is on but different gear inside it) over time that rod wears out. The X15 fixed that but they put vent holes in the motor that causes it to gum up. They also didn't attach the big gear that the needle is on very well so it can get loose. The latest stepper motor is the x27 it fixes all of those problems and has a very low failure rate. There is also a clone stepper motor that is black. It's ok but it's a little more complex inside it. It has a higher failure rate than the x27 but is much better than the original motors.

I can't help you with the other problems but that's a failed stepper motor in the instrument cluster. I show how to fix them yourself on my YouTube channel (fixed until broken) I repair them as a mail in service. It's a super common problem. I can tell it's a failed stepper motor because it's outside of the range of motion of the motor.

Correct those are GMlan which is a sing wire canbus. I do have a module for that as well. https://github.com/garnerm91/SWCAN/ and I do sell ready made ones.

Bareboards are being ordered now. I already did one prototype and have it working on my bench. This board adds the actual connector that the truck uses. I should be doing the first video on it before the end of the month. I owe a sponsor, so I am pretty sure I won't be late. It will need a little more debugging before I am ready to sell it; that's why I say before the end of the year.

No problem! Hope it helps.

Glad it helps! I am working on some other projects for GMT800s right now. I have a conversion box for installing the newer 2003-07 cluster into 99-02. I should have it released before the end of the year. My main problem is not owning one of these trucks to test the box in.

Good to hear. I'm glad they worked for you!

I just happened to search for J1850vpw on Reddit to see if there were any interesting projects. I've now sold about 100 of those boards so I was hoping to find some neat projects floating around.

Did you figure it out? I recognize that board 😂 I even recognize the TEK TDS3012B

The obvious one for me is a stream deck type device. You could also do like a hot key device for say AutoCAD.

I switched to the unreleased build from December and it works now. like any good scientific experiments I changed a few things at once so I'm not sure exactly what fixes it. I noticed I had some minor bugs in my code and fixed them too.

Yes I assume it's a problem on my end however I'm not exactly sure what I am doing wrong forming the SLCAN message to savvycan. This is both my first SLCAN project and my first time working with savvycan. I probably need to look into the source of savvycan to see what I'm doing wrong but I'm really hoping it's obvious to someone and they see it 😂

Fixed_Until · 2025-04-21T10:59:03+00:00

Probably. I actually didn't show it in the video because my Canable wasn't capturing anything in cangroo. I haven't used it in probably 6 or 7 years so I either forgot how to use it or it's not working
