Customer: I've been building the truck Everything in the truck works except the gauge cluster, took the dash apart to change the hvac blend actuator, and before I plugged it all back in I decided to check to make sure everything works (most of everything was plugged in aside from center console and seats) everything works but the cluster does nothing but light the service engine light very dim
JA: Are you hoping to fix this yourself?
Customer: Yes

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

In order to be able to help you with your cluster concern we are going to need complete information. Need to know the year and model of your Chevy. Post back when you can with this and I will have a look at the wiring diagrams and see if we can help you determine the cause.

Start first with Checking the power and ground feeds to the Instrument Panel Cluster . There have been lots of problems with the ground circuit which is located on the back of the engine on the left side. Power is feed on the pink and orange wires (pins B9 and B11) . There is one other ground as well shown in the wiring diagram enclosed in the link below. Copy and paste the link you your browser to open and view it.

using a power probe, it's telling me that there is ground at the orange wire on the cluster but 11.4v at the fuse in the box under the hood
Expert:  Ron replied 1 year ago.

That may very well be your problem, the Orange wire needs to be hot. What happens if you provide power to it?

Expert:  Ron replied 1 year ago.

Okay go back and recheck your grounds and if the ground check okay then you are likely looking at a failed cluster.

Customer: replied 1 year ago.
The wire is getting ground at the plug that plugs into the cluster without the cluster plugged in, I have 2 clusters both do not work
Expert:  Ron replied 1 year ago.

Well what happens if you cut it at the connector and then add battery voltage to it? The pink wire needs t be hot as well.

Customer: replied 1 year ago.
Nothing happens
Expert:  Ron replied 1 year ago.

Well if both the pink and the orange wire have battery voltage and your ground is okay then the cluster should work dont you think?

Customer: replied 1 year ago.
The black and white has ground, the pink and orange have 11.4 when I put it there wit the power probe and the key turned on nothing happens
Customer: replied 1 year ago.
Why would I be getting a ground signal from the orange wire, I get no signal from the pink wire
Customer: replied 1 year ago.
I agree the cluster should work, do you think it's a voltage issue?
Expert:  Ron replied 1 year ago.

If the orange wire was actually grounded dont you think the fuse would blow? Both the orange and pink wire need battery voltage . It sure sounds like a voltage issue or a bad cluster.

Customer: replied 1 year ago.
I agree
Customer: replied 1 year ago.
Everything else in the truck works great, yesterday I was getting power to the orange wire today I'm getting ground
Expert:  Ron replied 1 year ago.

Are you sure your two cluster are not just bad. Its very common for the clusters to fail. If you cut the orange wire a inch or so back from the connector and recheck the voltage on the wire coming out of the cluster is it still showing a ground?

Customer: replied 1 year ago.
the truck is all apart, it's a 2003 Chevy Avalanche 2500 body, with a 2003 Silverado 6.6l diesel swapped into it, the Harness from the front headlights to the rear taillights is from the Duramax, there is not a stitch of Avalanche wiring harness left in the truck so essentially it is a 2003 Silverado Duramax, the interior is totally disassembled I only plugged some things in radio, cluster hvac 4x4 selector, dimmer, headlight switch, the engine was just put in the starter is not bolted up no fuel plug or transfer case plugged in yet everything is just kinda hanging off, I just plugged some interior things in to make sure we had power to everything before we started to put it all together and everything works EXCEPT the cluster. Would this have anything to do with the cluster?
Customer: replied 1 year ago.
it shows ground right from the pin on the connector without the cluster even plugged in
Expert:  Ron replied 1 year ago.

Well its very likely something to do with the wiring from the change over but at this point I do not think I can fix it from here. Im going to open the post back up for you and hopefully someone else has done this type of change over.
