starts and idles fine.
No gages work, other than tach, speedometer.
Is this a PCM issue?

 

In the FAQ section here, is a factory service manual in .pdf format. Grab that, and do the cluster test. See what that reveals.

 

do the warning lights in the dash come on?
there are 2 fuses for the cluster fuse 14 and 17 I think

 

all the warning lights come on. Some stay on while driving. I checked the fuses under the hood and on the drivers side if the dash. All had continuity. I have not checked fir fuses in the cluster itself. But I will

 

11 year old thread! Start your own and give details like year. If your truck is a later year you can run the dash gauge test.

 

I did a few weeks ago.

Help!!!
1998 2500 V10 4x4:
I'm in the Wildwood, Florida area. I have a problem with my instrument cluster guages. Dash lights work, but none of the guages work (battery, temperature, tachometer, speedometer, oil or fuel). Throwing codes 920, 921 and 999. The words "no bus" DO NOT appear in the display. The overhead display works and shows compass and temp as it should but no codes. I bought a second (used) instrument cluster, that did not fix the problem. Truck starts runs and drives fine, every time. Truck does not die while running and idles fine. Ive check fuses both under the hood and on the side of the dash, they are all good.. Hope someone here can help figure this out and/or suggest a shop that can fix it without me having to sell the farm to pay for it. I have minimal to no experience in electronic diagnostic to figure this out. If additional info is needed please let me know. Thanks"
